round lcd display
Because the circular display area of a circular lcd display is different from the traditional square, this makes the circular display more attractive to consumers. However, circular displays are also difficult to make because of their round shape.
Because of the rapid development of smart wearable and smart home market, people have higher requirements for products. They are no longer limited to the function, but also the appearance. Like round dial and round knob, these have been deeply recorded in our minds. Color round display brings incomparable display effect to end users. After adding multi-touch screen to the round lcd display, users can touch the round screen and rotate and press the traditional knob. Bring more man-machine interaction functions, which can replace the original complex panel to make your products more concise and more advanced.

round lcd display
Compared with square displays, it is more difficult to make round display. For example, the cutting of round lcd display requires CNC or laser cutting due to its circular shape, and the backlight should also be made into a circle to match the round display. Therefore, the size of round screen is relatively small. We have the world’s most complete round screen, ranging from 0.9 “to 5”. The following is the product information:
