TFT LCD display module YX39501B

TNcolor320 x 480

Product overview
The Yousee YX39501B is a 3.95-inch SPI TFT LCD module with 320×480 resolution and ST7796S driver IC. Intended for industrial control panels, handheld devices and embedded HMI, the module uses an a-Si TN positive transmissive panel optimized for 12 O'Clock viewing to ensure clear front-view readability and stable luminance in fixed-orientation applications. The SPI interface facilitates MCU-based integration for cost-effective embedded systems.
