WF0128BTYAA4DNN0 is a 1.28 inch round TFT LCD featuring a 240x240 pixel resolution. This compact 1.28 TFT display integrates an IPS TFT-LCD panel and is driven by the GC9A01 IC, supporting SPI interface communication. With its round shape and vibrant image quality, it is ideal for modern compact applications.
This 1.28 inch TFT LCD module adopts IPS technology, offering high contrast and wide viewing angles of 80° from all directions (Left/Right/Up/Down). It delivers a contrast ratio of 1,000:1 (typical) and a brightness of 400 nits (typical) on an anti-glare surface. When the display or individual pixels are turned off, the IPS panel provides a deep, true-black background for superior visual performance.
If a capacitive touch interface is required, please refer to model number WF0128BTYAA4DNF10.
The module operates with a power supply voltage ranging from 2.7V to 3.3V (typical 2.8V). It functions reliably in temperatures between -20℃ to +70℃, with storage conditions from -30℃ to +80℃. This 1.28 inch round LCD is especially well-suited for wearable devices, smart gauges, and meter displays. It is also a great choice for integration into home automation systems, white appliances, and video-based applications.
