TFT LCD display module YX16901A

IPScolor240 x 280

Product Overview
The YX16901A is a 1.69-inch a-Si TFT LCD module with 240 × 280 RGB resolution and IPS full viewing angle. It uses a positive transmissive panel and integrates the ST7789V driver IC. The module supports a 4-wire SPI interface and is optimized for compact, low-voltage embedded systems and MCU-based designs requiring wide viewing angles and simplified integration.
