The YX35031A is a 3.5-inch high-resolution TFT LCD display module featuring 480×640 RGB resolution with RGB + SPI dual interface, designed for industrial HMI, medical devices, smart terminals, and embedded platforms.
With its high pixel density and All-O’Clock wide viewing angle, the display provides sharp text, detailed graphics, and consistent color performance from every direction. Powered by the HX8363A driver IC, it supports high-speed RGB video input together with SPI control, offering excellent flexibility for system designers.
The 640-pixel vertical resolution makes YX35031A especially suitable for Android-style UI layouts, Linux systems, and professional embedded user interfaces that require higher clarity and more display area than standard QVGA or WQVGA panels.
