TFT LCD display module YX13015A

IPScolor240 x 240

Overview
The Yousee YX13015A is a 1.28-inch round TFT LCD module with 240×240 RGB resolution and a 4-wire SPI interface. Designed for wearable electronics, smart home devices, portable medical instruments and embedded control systems, the module uses the GC9A01 driver IC and an IPS panel to provide All O'Clock viewing direction, consistent color reproduction and wide viewing angles. Its compact outline and 1.64 mm module thickness suit space-constrained applications while ensuring low power consumption and reliable optical performance.
