Circular LCD Screen, Circular LCD Display Module 128x128

Model No. RX128128A

We are now producing circular displays with different technologies for a variety of applications and markets. Compared to traditional rectangular displays, many needs for beautiful round circular displays have been increasing in the market. They are a good fit for many applications such as home appliances, consumer products, industrial products, etc. The resolution of this circular LCD display is 128x128. This display communicates over 8080, 6800/4-line/ 3-line SPI or I2C interface.
