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.
