2. Description of 3.95 inch touch screen module
chenghao is an LCD display supplier, providing OEM/ODM services for global display users. CH400WV17B-CTBA is an All Black Effect Touch Screen Display customized by chenghao for customers. It is a color active matrix thin film transistor (TFT) liquid crystal display (LCD) that uses amorphous silicon TFT as a switching device. It mainly includes a All Black Effect glass cover, a tft lcd panel, a driver IC, a backlight and FPC, etc.
(1) The glass cover is All Black Effect. Even when the screen is off, the display surface still looks pure black, and the components of the touch screen module cannot be seen through the glass cover.
(2) The Tft Lcd Panel has a 3.95” ( square screen ) diagonally measured active display area with 480(RGB)x480 dot resolution.
(3) The ST7701S mounted on the glass is used as the driver IC of the Touch Screen Module, and is interconnected with other components through the FPC. By inputting RGB signals to the driver IC, this Touch Screen Module can display 16M colors.
(4) The Back Light has 16 parallel white LEDs. By inputting IF=40mA and VF=25.6V to BL, the display screen can generate a Luminance of 300 cd/m2.
(5) FPC can also be customized according to customer requirements, such as modifying back-light and FPC structure, interface definition, etc.
