This display module features a 4.3-inch TN panel with a 480×272 resolution, 350 cd/m² luminance, and an ST7282 driver IC connected through an 8-bit RGB 40-pin interface.
Yes, touch functionality is optional. The module can be customized with either a resistive touch screen (RTP) or a capacitive touch screen (CTP) based on project needs.
The display operates reliably within a temperature range of -20℃ to +70℃, and can be safely stored between -30℃ and +80℃, suitable for challenging environments.
It is widely utilized in industrial automation (HMI interfaces, PLC control panels), medical devices (diagnostic equipment, monitors), smart energy meters, and IoT terminal systems.
It uses a standard 40-pin connection supporting an 8-bit RGB interface, complete with clock, sync, data enable, and dedicated touch panel signal pins.
