WF0128BTYAA4DNN0 is a round IPS TFT-LCD screen with a 1.28-inch diameter display with resolution 240x240 pixels. This round TFT display comprises an IPS TFT-LCD panel built with a GC9A01 driver IC that can communicate via SPI interface.
WF0128BTYAA4DNN0 is adopted IPS panel, which has the advantage of higher contrast, true black background when the display or pixel is off and wider viewing angle of Left:80 / Right:80 / Up:80 / Down:80 degree (typical), contrast ratio 1,000:1 (typical value), brightness 400 nits (typical value), anti-glare surface panel. If customers require Capacitive Touch Panel, please choose model No. WF0128BTYAA4DNF10.
The power supply voltage of LCM is from 2.7V to 3.3V, the typical value of 2.8V. It can be operating at temperatures from -20℃ to+ 70℃ and storage temperatures from -30℃ to +80℃. The display modules are suited for compact devices like smart gauges, wearable devices, and meter applications. They are also ideal for home automation products, white products, and video systems.
