TFT 1.28" 240x240, Round LCD Panel, Interface MCU (RGB/Parallel/SPI) IC GC9A01, Wide View Angle (IPS), 500cd/m², No touch

DESCRIPTION

The WFN0128DA2#0P0-FC is a compact 1.28-inch round TFT LCD module featuring a wide-view IPS panel and 240x240 high resolution. It is ideal for end products requiring round UI design, such as smart home controllers, wearable devices, and industrial control knobs.

This module integrates the GC9A01 driver IC and supports multiple display interfaces, including 8/9/16/18-bit MCU, 3/4-wire SPI serial interface, and 16/18-bit RGB, enabling flexible integration with various host platforms. The panel brightness reaches 500 cd/m², with a contrast ratio of 700:1, operating temperature range from -20°C to +70°C, and an LED lifetime of 50,000 hours, providing excellent display performance and long-term reliability.

Recommended Application Areas:

  • Smart Home: smart switches, voice assistant displays, lighting control panels
  • HVAC and Appliance Control: home thermostats, air conditioning controllers
  • Industrial Equipment: round control panels, rotary control modules
  • Medical and Wearable Devices: handheld diagnostic tools, health monitoring bands, sports watches
  • Automotive and Instrument Interfaces: electronic dials, auxiliary instrument clusters, rotary displays
  • Audio and Consumer Devices: digital tuners, audio rotary displays, Hi-Fi audio control interfaces
