TFT LCD display module YX28076A

IPScolorhigh-resolution

Product overview
The YX28076A is a 2.76-inch high-resolution round TFT-LCD display module with 480×480 RGB resolution and a 3SPI + 18-bit RGB interface. It is driven by the ST7701S controller and uses IPS (All O'Clock) technology to provide wide viewing angles and consistent color reproduction. The module is intended for smart home products, industrial control systems, medical devices, wearable electronics and embedded HMI applications.
