WF0128-240240BD#0P19B-FC

TFT 1.28" 240x240, Round with KNOB, LCD + IC Controller, Interface MCU (SPI) IC GC9A01, Wide View Angle (IPS), 320cd/m², Capacitive touch panel

 

DESCRIPTION

 

WF0128-240240BD#0P19B-FC is a diameter 1.28-inch round IPS TFT-LCD module with KNOB with capacitive touch panel made of resolution of 240x240 pixels. This round TFT display with KNOB comprises an IPS TFT-LCD panel built with a GC9A01 driver IC that can communicate via SPI interface and is equipped with a capacitive touch panel that supports I2C interface.

WF0128-240240BD#0P19B-FC 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 320 nits (typical value), glare surface panel.

The power supply voltage for analog(VCI)is from 2.65 to 3.3 V, the typical value of 2.8V. It can operate temperatures from -20℃ to+ 70℃ and storage temperatures from -30℃ to +80℃. The round TFT display modules are suited for compact devices like wearable devices, and smart home applications.
