As we know, the display screen is easy to broken, if we meet this problem in our daily life, what should we do? How to repair cell phone display screen?
Before we repair the screen, it is significant for us to have a comprehensive understanding about the principle of the mobile phone display screen.
Mobile phone display module is a high integrated product. Parallel port type LCD of the D0 ~~ D7 (D8 to D15), the R / W (/ the RD / WR), C5, and A0 is serial type in the SCL, the SDA replaced, these are used to achieve control drive controller chip on the motherboard CPU such as opening screen, turn off screen, display characters all display operation control and data. VLCD is used to adjust the display contrast of the screen, according to the specific module control voltage; VCC (V DD), GND (VSS) supplies power to the drive control chip. Of course, now, mobile phone display module has a wide range of backlight components and drive components, common light-emitting diodes, flat light-emitting block, are low-voltage drive, but there are also the AC110V driven EL backlight.
Display controller receives display instructions and data through analysis and judgment from LCD. sent over by the, storage, and the scan will be displayed in a certain clock speed dot-matrix information output to the row and column drive to ≥ 75Hz frame rate update screen, when the human eye is in the reflection of outside light, you feel the display screen appears on the display content.
Now, after we have a comprehensive understanding of display screen, next, we will talk something about common faults and how to repair it.
1. Mechanical damage (large area of the black block, cracked, scratched, etc.), such phenomena can not be repaired, only to change the screen.
2. No appearance of injury phenomenon, but there is no display. Class phenomenon should first make sure that the host portion of the normal working of the phone to start (host normally only need to press the power button can dial “112″ can be). First check whether all pins good contact, with a multimeter (multimeter through the conductive properties of the conductive rubber conductive rubber need to check off block the conductive measuring tape at both ends).Above to ensure that the normal can re-boot test, if it does not show, can be checked by measuring voltage and waveform.
3. There, but the lack of pen less program. Parallel port type liquid crystal may be due to the individual data lines D0 ~ D7 (D8 ~ D15) pin connection is bad, but exclude some fault can only say that the LCD module is broken, gently shake the module a few times and try not you can not do anything
4. Display is too dark or too light, the backlight of the original does not shine. Such failures only solve its for VLCD and backlight voltage is not normal can be.

The principle of capacitive touch screen
Now most of us have cell phones, and the majority of the touch screen is capacitive, and this article we will share something about the principle of capacitive touch screen.
The sensitive screen of capacitive touch screen is a four-layer composite glass screen; the glass screen of the inner surface of the sandwich coated with a conductive layer, the outermost layer is a thin layer of silica glass protective layer. When our fingers touch the surface of the sensitive screen, the electric field of the human body form a coupling capacitor. For high frequency current, capacitance is the direct conductor, so fingers absorb a very small current from contact point. The current points outflow, and flows through to the four corners of the four electrodes and the finger is proportional to the distance from the electrodes on the four corners of the touch screen. Controller gets the location of the touch points through the accurate calculation of the four current ratio.
Compared to traditional resistive touch screen, capacitive touch screen have these advantages as the following aspects:
1. Novel. The capacitive touch screen supports multi-touch operation, so the operation is more intuitive and more fun.
2. It is not easy to inadvertently. The capacitive touch screen need to induce body’s current, only the human body can operate, there will be no reaction when other objects touch it, so basically, avoid the possibility of inadvertently.
3. Durability. Compared to the resistive touch screen, capacitive touch screen in a dust-proof, waterproof, wear better performance.
As a legitimate touch-screen technology, the capacitive touch screen with a gorgeous interface, multi-touch, only the human body sensors and other advantages, but at the same time, it also has the following disadvantages:
1. The accuracy is not enough. For technical reasons, compared to the capacitive touch screen, resistive touch screen is not accurate, which had been lacking. And only use your finger to input, it is difficult to recognize complex locus on small screen handwriting.
2. Vulnerable to environmental impacts. Environmental factors like temperature and humidity changes can also lead to instability of the capacitive touch screen and even drift. Such as a user use the screen and close to the body, the screen may cause drift, even a crowded can also cause drift. This is mainly due to the capacitive touch screen technology works, although the distance from the screen of the user’s finger is closer, but around the screen, there are a lot of volume is much larger than the electric field of the fingers simultaneously, which would affect the judgment of the touch location.
3. Expensive. In addition, there are some technical difficulties of the capacitive touch-screen touch pad attached to the LCD panel, the yield is not high, so virtually, this has also increased the cost of capacitive touch screen.
In the past, due to cost and technical factors, the use of the resistance control panel is far more than the capacitive touch screen technology. But within the last stage, with technological advances and mass, the price of capacitive touch screens are falling, and the price gap with resistive touch screen is getting smaller and smaller. So, the majority of the cell phone manufactures all use the capacitive touch screen.

The Infrared Light Source of Touch Screen Technology
Last article, we have a rough introduction about multi-point touch screen technology, there are three points that we have to talk. The first aspect is infrared.
In the multi-touch technology, the main role of the infrared light source is the difference between the touch surfaces of the visual interface and a finger or object traces. Many systems use a projector or monitor as a display of equipment, how to make the camera only to read the finger or an object feedback is that we need to focus, and modified the camera so that it only reads what we touch in the surface and feedback the touch point which we need.
The majority of acrylic (Acrylic) manufacturer in the production of acrylic has strengthened the ability to undermine the infrared above 900nm, this can help to reduce the absorption of solar heat when used as the window. Many cameras amend to reduce the interference of 940nm infrared sensitivity and reduce sunlight.
The infrared light is through the infrared light-emitting diodes. Based on the optical principle of multi-touch technology (especially the LED-LP as well as by FTIR), infrared light-emitting diodes can be used as an effective infrared light source to improve the infrared light that we need. Scattered light multi-point touch technology (DI) is not necessarily to the infrared light emitting diode, but also can install the infrared light-emitting diode infrared light source group. The multi-touch technology of the Laser Plane (LLP) uses the infrared laser as an infrared light source.
Under normal circumstances, you can purchase a single infrared light emitting diode, or buy infrared light-emitting diodes.
Single infrared light emitting diode: the price of a single infrared light emitting diode is relative inexpensive, can make use of FTIR, DSI easily, as well as LED-LP technology, equipment, production of light-emitting diode box, but we need to understand how to welding circuit. The most commonly used model is the Osram SFH 485P, if you want to use the LCD panel as the display devices, then you need greater brightness infrared light – emitting diodes.
Infrared light emitting diodes with: This is the bands of infrared light-emitting patch production, combined with flexible flat cable, which is very convenient. It has been assembled after we purchase, we need only attached to the acrylic four sides. The best infrared light-emitting diodes fromUnited Statesare recognized as the best quality.
Infrared transmitter: for the scattering of light multi-touch device, the device of this approach is simpler, we only need to illuminate the box through infrared transmitter, but we need to note is how to eliminate the problem of area is too bright.
Before we purchase the infrared light-emitting diodes, we need to pay great attention to the parameter list of the light-emitting diode, wavelength, angle, power, etc., these are the focus. After we have a comprehensive understanding about infrared infrared light source, we will have a full use of our touch screen.

What is Mobile Phone Screen Resolution?
Nowadays, almost everyone has a cell phone, but what is mobile phone screen resolution? I think you may know a little about your touch screen resolution, so let’s look at the details.
The Concept of Resolution
The concept of resolution is particular simple. We mentioned a concept called pixels, the screen image is made by a small box combination, and each grid is a pixel. If the screen resolution is 240×320 that means this high screen of 320 small squares wide and 240 small squares. – As for this little box, determined by the screen size. For the same 240×320 resolution screen, the screen size is smaller which means the display is fine, because a volume accommodate an equal number of small squares, squares smaller, the higher degree of display.
Imagine a 3.5-inch screen and a 4.7-inch screen, screen resolution are 480×800, then certainly a 3.5-inch screen sophistication, and for 4.7 inches, using naked eye distinguish the small grid caused by the particles better.
VGA
VGA refers to a resolution of 480×640. Early QQVGA after long-term widely used is a QVGA screen at 240×320 resolution screen. QVGA used by Nokia widely. People nicknamed QVGA resolution screen for the Q screen. Quarter (because the resolution is quarter of VGA, so called QVGA)
In the course of development of the VGA resolution, there are a number of different resolutions, such as HVGA, HVGA resolution of 320 × 480 (half the resolution of the VGA, so called Half-VGA). HVGA resolution has also been widely adopted, the most famous is iPhone in 2007, the iPhone’s 3 are used HVGA resolution 3.5 ‘ phone screen. – Earlier HTC models of this resolution, such as the HTC G1/G2/G3.
With the development of touch screen technology, the high score screen is becoming popular this year, various brand mobile phones began to use qHD resolution screen, 540×960. Famous brand flagship already have qHD touch screen resolution, such as the HTC G14, (Sensation), moto Droid The Droid the Razr.
The promotion of qHD and the release of the iPhone 4 is related, in 2010, Apple released the iPhone 4, the touch screen resolution upgrade to an unprecedented height (640×960, 3.5 ‘screen), which make the naked eye can not distinguish between pixels particles is indeed the innovations on the screen display.
Recent years, Batch of Samsung’s cell phone use the phone screen more than 4.7 ‘, the screen resolution has been used 720×1280. Now with such a high resolution which less than 5 ‘on the screen is indeed satisfy people’s increasing demand for mobile phones display screen.

Touch Screen is Good or Not?
The touch screen has
been widely used, and touch gestures will replace the mouse and the
physical keys like the input gradually, taking the new experience for
the popularization of electronic products such as mobile phones and
computers.
Natural and intuition. Everyone knows how to click with fingers, it easier to operate if it sames like the objects in our daily life, which is one of the characteristics of the natural user interface (NUI-Natural User Interface).
Less intrusive. Typing and mouse clicks with sound, but the touch screen is silent and convenient, you just need use your finger, no need to find a pen.
Portable. Using the touch screen is able to complete most tasks and it is more flexible. Don’t require any working platform and an external device such as a mouse and keyboard.
Direct and integrate. By contrast with the mouse pointer move, use finger and object on the touch screen interaction allows users to integrate into the operation.
Touch provides the real interaction, the dynamic effects of the move, sliding and rotation of elements in the interface is also consistent with the laws of the movement of objects. But new technology is not perfect, there are some problems:
Hard to operate. Fingers can not click the smaller control but the mouse pointer is accurate to 1 pixel, fingertip or the finger belly determines the accuracy of touch.
Difficult to enter. Limited space to touch, it is difficult to change the cursor position and the virtual keyboard call to the large section.
Difficult to click on the edge of the screen area. With one hand hold the touch-screen phone, the thumb, thumb long as the radius of the phone screen about a quarter of the ring area most easily to click on the farther from this area, the more difficult to click.
The so-called design, is to solve the problems listed above, the design is going to meet the finger touch interface, and play to the advantages of touch screen’s operation, mining the update operation on the existing basis. By increasing the height and spacing between controls, you can increase the clickable area to enhance the accuracy of touch, at the same time also need to pay attention to the following question:
Reduce the number of clicks. Finger lift and press laborious than a mouse click.
Reduce the finger displacement. Finger movement is not like a pointer to adjust the speed of the pan.
In this article, we talk something about the merits and demerit about touch screen technology, if you want to get more information, click the following link: http://www.protect-scrren.com/

How to Choose a Best Touch Screen?
In recent years, with the tremendous development of touch screen technology, more and more people choose the touch screen , but few people know how to choose a best touch screen, what should be noticed when they decede to buy it. Here are some advices for you to solve it.
Touch screen as a new part in today’s product design, within the past three years have there are many touch-screen factory, the users may can not distinguish the quality of touch-screen is good bad from the exterior, we put forward some simple methods can identify the quality of products.
In addition, there are 4-wire, 5 wire, 6 wire and 8 wire manufacturers in the market; in the end what kind of design is consistent with our needs? Around look at a touch screen when to get a touch screen that printed with a green border, if any, probably we guess it is insulating ink, but the insulation ink may also be translucent color.
In any case, the quality of the insulating ink design is worse than the substrate double-sided adhesive. Also take a look at the outlet end of the design, if the power of outlet tail connection with the touch screen is not sticky enough, this touch screen is easy to broken, if it is broken and to be repaired is unlikely. Furthermore, take the touch screen to hands with the 60 ° angle to look at the surface, if it is a Newton ring, if Newton rings generated by touch screen, that this factory is not enough experience in the handling of the Newton ring problem. With your fingers touch the touch screen feel if it is not a touch screen up and down the second floor, felt, illustrate this factory is still some way to provide a good quality touch screen products.
Furthermore, depending on the touch screen designed we provide a few comments. 4-wire design is the most basic approach, but also is the mainstream of today’s 90% touch screen plant design, because the XY axis line of the touch screen to directly pull out conversion through the touch screen controller can read the user touch position. 4-wire design is best used in the products of the small size, small size is under the size of 10.4”, because the touch screen switch and calculate the touch location is relay on the surface resistive which connect voltage. Surface resistance may aging because the sake of the environment or other causes, it is not easy to be felt by the user on the small size of the touch screen, 4-wire touch screen is a good choice. 8-wire touch screen can make up the occurrence of the phenomenon of large size on 4-wire touch screen, so the 8-wire type touch screen design a “sensing line” on each side of if meet the occurrence of aging in surface resistance that can immediately adjust back to normal by induction line, so the 8-wire design is a design on the size of more than 10.4 “.
There are some technical indicators about the touch screen, if you can have a comprehensive understand of it, you can choose a best touch screen easily.

How to choose iPhone4/4s protective cases
Although Steve Jobs has died, the iPhone is still very popular, while the iPhone protective case,
iPhone protector, iPhone shells are selling hot. But the products on
the market varies, due to the original authentic is general valuable, so
the market imitation brand imitate the original accessories. Now I will
teach you how to choose the iPhone4s protective cases or iPhone4s
shells. There are several aspects we can think out after we intend to
purchase one.
First, The Brand
(1) Brand and non brand
In iPhone4/4s popular era, the accessories also developed for a long time. But many IPhone users almost are no understanding about the brand of phone shells or cases. When they choose it and miss the most suitable product. In this age, brand is the most powerful intangible assets, since the brand has formed a brand, there must be superior to similar products in place, the quality is also elegant. So in the process of selection, we are all determined to observe, and more elegant, select the appropriate brand, the appropriate product.
(2) The brand of professional degrees
Between the brands, we have to compare. The best choice is high professional brand, which is concentrated products in the field is mobile phone shell or further concentrated in the female / male phone cases field. There kinds of brands are often better to explore the psychological needs of consumers, and produce the specialized products for specific consumers, higher satisfaction and reputation. For example, the majority of mobile phone cases manufacturers are mixture, it means the men and women both can choose, but there are specifically for young women’s fashion phone cases brand, the market positioning is very clear, high professionalism, wide optional.
Second, the material
The material of IPhone4/4s protective cases are varieties. Probably silicone, TPU, PC, ABS, leather, metal material are the most frequent material we have heard. Silicone is popular relatively a few years ago. Due to more materials and process development in recent years, the user dissatisfac many of the shortcomings of the silicone, and lost the advantage gradually. Silicone is difficult to radiating, and the process is poor and appears to the low-end, modeling is also single.
Now the more popular mobile iPhone4 protective cases made of PC and ABS material, PC generic polycarbonate, and thermoplastic engineering plastics. The impact resistance of PC material is good, and it is also good toughness, high transparency, non-toxic, processing convenience. Generally, PC cases plating pattern or touch rubber coating of oil in the process, you can also transfer some of the patterns, so that the mobile phone protective shell looks more upscale and refined, very pretty.
ABS material is a little hard relatively, protective cover of the mobile phone of pure ABS material rarely, in the heat resistance and impact resistance is worse than PC material, but the ABS material mobility, coloring and surface coating and plating performance is pretty good. Now have a new process called in-mold injection molding, basic ABS plastic material, the surface of the material is PET. The advantage of this process is the surface of cases can be richer patterns, and similar transfer process than the transfer pattern is more refined, more perfect detail, strong texture, look tasteful.
The brand and the materials are the very important aspects for iPone4/4s user to purchase a phone cases. If you want to get more information about touch screen or phone protective cases, please visit our homepage.

The Introduction of Nokia Touch Screen Phones
In the cell phone market, more and more manufactures decide to enter ,
Nokia who is a former mobile phone giant will never fall behind in touch screen phone market. So let’s look at the Nokia touch screen phones.
When the Nokia boss Stephen Elop said to media that Nokia decide to enter the touch screen market with the new Windows OS. I estimate that all the people aware of the dominance in the phone market. When they suffered the impact from other touch screen manufactures, such as Apple, Samsung, HTC and so forth. So, they cooperate with Microsoft and hope they can regain the previous dominance when they release the Windows OS.
After Nokia released the Windows phone, Nokia technology announced to the public that the new Windows phone will be ornate in the appearance, but when you hold it, you will also have a good feeling. Now android touch screen phone is a mainstream, but Nokia want to rival with other mature manufactures, Nokia have to geared up to have a better design and also have to get the better user experience. For this, according to the released Nokia Windows phone which have a hot market feedback, and Nokia has a good customer support, such as when the user meet the problem of display screen, they update the software with the fastest speed to solve the problem. If we just consider this aspect, Nokia Windows touch screen phone is reliable. But this is just a little competition with the mature android phone manufactures who also get the good reputation, especially, when the Nokia Windows phones is still a baby in the phone market. So, now, it’s hard to judge if Nokia can get more cake in touch screen technology market.
The display screen of Nokia’s first smartphone on Windows OS is larger (3.5-4.0 inches) than the regular touch screen devices which are running on Symbian. Another aspect in the category to consider is Nokia’s top notch image quality which has been persistent all throughout each and every model that Nokia launched in the market. The again with existing models like Nokia N8 we are kind of spoil for choice in terms of contrast and clarity that an AMOLED screen has to offer in all high end smartphone models. It is only a matter of time when Nokia’s clear black display screen technology will be put to test. It means that we are going to have the better visual experience if we get one.
In addition, there are more telecommunications giant are entering this fierce market, such as Huawei technology. So, for the Nokia touch screen phone, what I can say is the competition is strong and the hope is still exit.
When the Nokia boss Stephen Elop said to media that Nokia decide to enter the touch screen market with the new Windows OS. I estimate that all the people aware of the dominance in the phone market. When they suffered the impact from other touch screen manufactures, such as Apple, Samsung, HTC and so forth. So, they cooperate with Microsoft and hope they can regain the previous dominance when they release the Windows OS.
After Nokia released the Windows phone, Nokia technology announced to the public that the new Windows phone will be ornate in the appearance, but when you hold it, you will also have a good feeling. Now android touch screen phone is a mainstream, but Nokia want to rival with other mature manufactures, Nokia have to geared up to have a better design and also have to get the better user experience. For this, according to the released Nokia Windows phone which have a hot market feedback, and Nokia has a good customer support, such as when the user meet the problem of display screen, they update the software with the fastest speed to solve the problem. If we just consider this aspect, Nokia Windows touch screen phone is reliable. But this is just a little competition with the mature android phone manufactures who also get the good reputation, especially, when the Nokia Windows phones is still a baby in the phone market. So, now, it’s hard to judge if Nokia can get more cake in touch screen technology market.

How to distinguish resistive touch screen and capacitive touch screen?
The development of touch screen technology
grows more and more fierce, but for the ordinary people, we may also
heard that resistive touch screen and capacitive touch screen, do you
want to learn more about there two most common touch screen? In our
daily life, do you know how to distinguish resistive touch screen and capacitive touch screen?
Resistive screen: the body of resistive touch screen is a multi-layer composite films, which made of glass or plexiglass as a grass-roots and coated with a transparent conductive layer (ITO, film) in the surface. And covered with a surface-hardened smooth and scratch-resistant plastic layer.The capacitive screen: the principle of capacitive touch-screen depends on the current sense of the human body, touch screen composited with a four-layer glass screen. In last article we have shared” introduction of Capacitive Touch Screen and Resistive Touch Screen”, if you don’t know the basic information of them, please read that article first.
I have summarized four simplest ways to distinguish resistive touch screen and capacitive touch screen, here we go.
1. Look
Indoors, regardless of the resistive touch screen or a capacitive screen, the visual effects of both are very good. But if in the sun, the effect may differ materially. Resistance screen performance will be unsatisfactory; because of the additional screen level reflected a lot of sun. Such as the classic cell phone Motorola “Ming” series, the visual effects is terrible if we just use our naked eyes in the sun.
2. Touch
Resistive touch screen required pressure to the screen of all layers come into contact, you can use a finger, stylus, etc. to operate. The capacitive touch screen capacitive sensor system can be active with the most subtle touch of the finger surface Non-living, nails and others is invalid.
3. Experience
The fundamental characteristic of the resistance screen on top is soft, need to be press down, which makes the screen very prone to scratches. However, due to the resistive screen can be operated with a stylus or fingernail, so the cleanliness of the screen is quite good. The capacitive screen outer layer can use glass, so that it’s not indestructible, but there may be a serious impact on fragmentation, and the glass is easier to handle in the daily grazing and stains.
4. Purchase Cost
Resistive screen is cheep relatively, capacitive screen is more expensive.
If you read these four tips, I am sure that you can distinguish the resistive touch screen and capacitive touch screen, and there is also another simple way for you to know the difference between them, you can go to a professional store and pretend want to buy a screen, so you can get the specialized explain about them from the salesman.

The introduction of Capacitive Touch Screen and Resistive Touch Screen
With the development of the touch screen
technology of cell phones, there are a variety of touch screens full of
our life, today we introduce something about the capacitive touch
screen and resistive touch screen.
Capacitive touch screen
The principle of capacitive touch screen is relatively simple. Each electrode is the same potential, if there is no one touches the screen. But if someone touches the capacitive touch screen with the fingers, the body, the fingers and the conductor layer to form a coupling capacitor, electrodes of the four sides issue the current and the flow to contacts. Theoretically, the distance flow through the four electrodes and the finger to the four corners is proportional. The controller calculated the four current ratios and can get the position of the contacts.
The capacitive screen phone can operate only with your fingers, and we can’t operate with ordinary stylus, but you can use a dedicated capacitive screen stylus, which is not necessary for the capacitive screen; resistance screen phone can operate with your fingers or the stylus. More and more people concerned about the capacitive screen phone which can operate with a finger.
And now so many manufactures use capacitive touch screens that capacitive touch screen become the mainstream of the touch screen technology market.
Resistive touch screen
Resistive touch screen (Touch panel of resistance), also named resistive touch panel which is a LCD display device that can receive the input signal. When the graphic button is touched, according to the pre-programmed, haptic feedback system can drive a variety of connected devices, which can replace the mechanical button panel, and create vivid video effect by the LCD screen.
① They are a complete isolation of the working environment, not afraid of dust, water vapor and oil.
② They can touch by anything and can be used draw and write, which is their comparative advantage.
③ The accuracy of resistive touch screen depends only on the accuracy of the A / D converter, so it can easily reach 4096 * 4096. By contrast, in guarantee resolution accuracy, five-wire resistive is better than four-wire resistance, but the cost is to high, Therefore, the price is very expensive.
In this article, we share some details about the capacitive touch screen and resistive touch screen technology, if you are interested in this kind of articles, our blog will be your excellent choice.
