GC9A01 Round TFT LCD Display 1.28-Inch 240x240 Module - RFA401280B-AYW-DNF1 - Raystar

1.28-Inch GC9A01 Round TFT LCD Display Module 240x240 SPI (GC9A01 IC)

Model No. RFA401280B-AYW-DNF1

The RFA401280B-AYW-DNF1 is a 1.28-inch round TFT LCD module featuring a 240×240 resolution, designed as a high-performance GC9A01 display with a built-in GC9A01 driver IC. This GC9A01 round display supports the SPI interface, simplifying connection to microcontrollers and making it well-suited for compact, circular display designs. As a 240x240 round LCD GC9A01 solution, it utilizes IPS technology to deliver wide viewing angles of 80° in all directions with consistent color performance.

The RFA401280B-AYW-DNF1 GC9A01 240x240 display operates with a 2.65–3.3 V power supply and supports a wide operating temperature range from -20°C to +70°C. It also integrates a projected capacitive touch panel (PCAP) with the CST816D controller, enabling single-finger touch and gesture recognition via an I²C interface. The LED backlight offers a typical lifetime of 20,000 hours, ensuring long-term reliability for industrial and portable devices.
