The 4.3-inch LCD Touch Display  (Model No. WTY043734A01LMT) is of a color TFT LCD display panel with 480×272 resolution and standard 50pin RGB interface, which support sunlight-readable, TN Technology, optical bonding/tape bonding.

The touch panel is of a G+G structure capacitive touch panel, which is composed of a cover glass, sensor glass, driver IC and FPC. It is driven by IC Chip N8110, which utilizes an I2C interface and supports 5 points of touch.

The capacitive touch screen is made up of a glass panel that is coated with a material.
The property of this material is that it can store electrical charge. So the capacitive touchscreens basically stores electrical charge.
But for good, Human body can also store charge. So, when you touch this screen with your finger, some of these charges on the screen gets transferred to your finger. The oscillator circuits located at the corner of your system will then sense this decrease in the charge on screen and the spot the exact location where touch occurred, and then transfers this specified information to the touchscreen driver software.
