2. Description
ChengHao Display model CH400WV17A 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 TFT LCD panel, a driving IC, a back-light, and FPC.
This TFT LCD has a 4.0 ( Square screen ) inch diagonally measured active display area with 480*480 pixel .
The driver used for this project is the ST7701S and can display 16.7M colors by signal input. The driver is mounted on the glass and the interconnection via FPC including components to drive the display module. Support SPI+RGB interface.
In addition, FPC can also be customized according to customer requirements, such as modifying back-light and FPC structure, interface definition, etc.
RoHS Compliance & Halogen Free.
