The YX35023A is a 3.5-inch high-resolution TFT LCD display module featuring 480×800 RGB resolution with a SPI + RGB dual interface, designed for industrial HMI, medical equipment, smart terminals, and embedded systems.
With its high pixel density and All-O’Clock wide viewing angle, the display delivers sharp text, detailed graphics, and consistent color performance from every direction. Powered by the ST7701S driver IC, it supports both MCU-based SPI control and high-speed RGB video input, providing flexible integration for a wide range of system architectures.
The 800-pixel vertical resolution makes YX35023A ideal for Android-style UI layouts, Linux systems, and professional embedded interfaces that require more information on a compact 3.5-inch screen.
