7 inch capacitive touch screen replacement
When a capacitive panel is touched, a small amount of charge is drawn to the point of contact, which becomes a functional capacitor. The change in the electrostatic field is measured to find the location. In some designs, circuits located at each corner of the panel measure the charge and send the information to the controller for processing. In multi-touchscreens, sensors are arranged in a grid to enable more complex input.

How do the touch screen work?
1.Virtually infinite options for user interface design and flexibility compared to physical buttons/switches.
2.Easy-to-use interface for any industry. (e.g., automotive and retail touch screens)
3.Requires less space – integrated design eliminates the need for external keyboards and other components.
4.Sealing options can make touch screens highly resistant to environmental conditions.
