7 Inch industrial capacitive touch screen
In the capacitive system, a layer that stores electrical charge is placed on the glass panel of the monitor. When a user touches the monitor with his or her finger, some of the charge is transferred to the user, so the charge on the capacitive layer decreases. This decrease is measured in circuits located at each corner of the monitor. The computer calculates, from the relative differences in charge at each corner, exactly where the touch event took place and then relays that information to the touch-screen driver software. One advantage that the capacitive system has over the resistive system is that it transmits almost 90 percent of the light from the monitor, whereas the resistive system only transmits about 75 percent. This gives the capacitive system a much clearer picture than the resistive system.
Cover Glass Dimension
Cover Lens VA
Interface of CTP
IC of Touch Screen
The controllers of chips like CYPRESS, Atmel, ILITEK,EETI, Goodix and FocalTech are popular used in our touchscreen panels. The size less than 7"(including 7") mostly works with GOODIX AND FOCALTECH IC chips. And the interface is I2C(IIC). The size over than 10.1", we choose ILITEK. If the clients have requirements for very thick cover glass, we use EETI IC chips.
