2. Description of 320*480 tft lcd panel
ChengHao Display model CH350HV16A is a color active matrix TFT
(thin film transistor) LCD (liquid crystal display) that uses
amorphous silicon TFT as a switching devic, mainly including a Tn
TFT Lcd Panel, driver IC, backlight (BL) and FPC several part.
The Tft Lcd Panel has a color display area with a diagonal
measurement of 3.5 inch, which can display 320*480 resolution
images.
The driver IC used is ST7796, which is mounted on glass and
interconnected with other components through FPC. Support
SPI/MCU/RGB/MIPI Multi-interface.
The FPC and BL can be customized according to customer needs,
including the brightness of BL, the shape and structure of FPC,
etc.
In addition, CH350HV16A supports the installation and removal of
touch functions, such as capacitive touch panel and Resistive touch
panel.
Comply with CE and ROSH standards.
