TFT LCD display module YX19002A

IPScolor170 x 320

Product overview
The YX19002A is a 1.9-inch IPS TFT-LCD module with 170×320 RGB resolution and a combined 3SPI + RGB interface. Driven by the ST7789V driver IC, it provides consistent color reproduction, All O'Clock IPS viewing angle and is optimized for compact embedded and portable systems used in industrial control, handheld terminals, smart home, medical and IoT equipment. The module's slim outline and lightweight construction suit space-constrained designs (outline: 25.80 × 49.72 × 1.40 mm).
