2.8 Inch Industrial Round TFT LCD Display Module (480x480, 350 Nits, ST7701S, HDMI Board)
This 2.8-inch round TFT LCD display module features a high-density 480x480 circular resolution powered by the ST7701S driver IC. Rated at 350 nits brightness, it provides bright, crisp visuals for custom smart controllers, automotive gauges, and industrial meters.
Engineered for high environmental durability, this display operates smoothly across a wide temperature range of -20°C to 70°C and tolerates storage temperatures from -30°C to 80°C. Utilizing a Normally Black a-Si TFT panel, it guarantees wide viewing angles and vivid color reproduction
The module comes equipped with a plug-and-play HDMI driver board, bridging the display's native 3SPI+18RGB interface to standard HDMI output. This enables fast setup with Raspberry Pi, Windows PCs, and Linux single-board computers without complex low-level panel driver programming.
