2. Description of 480x480 Round touch display
ChengHao Display model CH210WV01A-CT is a color active matrix thin film transistor (TFT) liquid crystal display (LCD) that uses amorphous silicon TFT as a switching device. This model is composed of a capacitive touch panel, a TFT LCD panel, a driving IC, a high brightness back-light, a capacitive touch panel and FPC.
This TFT LCD has a 2.1 (Round screen) inch diagonally measured active display area with 480*480 resolution.
This circular touch panel is capacitive (CTP), using CST830 as a driver IC to communicate with other components via I2C interface. Support multi-touch.
The driving IC is the ST7701S and can display 65K colors by 3line SPI or R.G.B. signal input. The driver is mounted on the glass and the interconnection via FPC including components to drive the display module. Support RGB interface.
In addition, FPC can also be customized according to customer requirements, such as modifying back-light and CTP structure, interface definition, etc.
RoHS Compliance & Halogen Free.
