With the development of science and technology, the LCD industry is also constantly moving forward, our mobile phones from buttons, strokes to finger touch, and touch screen is added on the surface of the LCD screen, to play the function of touch display. Touch screen is the use of human body current induction to work. This article focuses on introducing the meaning of touch screen, touch screen types and characteristics of what, I hope to help you.
What are the types of touch screens?
There are two types of touch screen: capacitive touch screen
and resistive touch screen. Capacitive touch screen
is used with finger contact directly, such as mobile phone; The resistive touch screen must be directly touched with a stylus and only under certain pressure, because it works by current induction of ITO in the upper and lower layers through pressure.
What are the features of capacitive touch screens
1, capacitive touch screen only needs to touch, and does not need pressure to generate signals.
2. Capacitive touch screen
requires only one or no correction after production, while resistance technology requires regular correction.
3. The capacitive touch screens
takes a long time to use, because the components in the capacitor touch screen do not need any movement; In a resistive touch screen, the ITO film on the top layer needs to be thin enough to be flexible enough to bend down and reach the ITO film below.
4. Capacitor technology is superior to resistor technology in light loss and system power consumption.
5. Capacitive technology wear resistance, long life, low maintenance cost when users use.
