AT070TN92 Pin Information
The AT070TN92 uses a standard RGB parallel interface. Its pins are mainly grouped into power, backlight, voltage control, and data signals. The panel has separate LED backlight power pins (LED+ / LED−) for the anode and cathode. It also includes digital power (DVDD), analog power (AVDD), and several GND pins. In addition, pins such as VCOM, VGH, and VGL provide the key voltages needed for LCD driving.
For signal control, the AT070TN92 supports 24-bit RGB data, with 8 bits each for Red, Green, and Blue. Some bits can also work in 6-bit mode. It supports HS, VS, and DE sync signals, and works with both DE mode and Sync mode. The panel also provides U/D and L/R pins for up/down and left/right display direction control, making installation more flexible. DCLK is used as the sampling clock, RESET is for global reset, and the DITHB pin supports dithering to improve image quality at lower color depth. The pin layout is clear and easy to connect to the main control board.
