More Details about this 1.4” Circular Screen

This 1.4-inch OLED display has a circular shape with a 400×400 resolution.

This AMOLED screen emits light from its own organic materials. This is why it has a high contrast ratio of 100,000:1, and a 160 degrees wide viewing angle.

It can also show all 16.7 million colours in the NTSC colour gamut. With 350 cd/m2 brightness, users can see bright and sharp images.

It has a MIPI interface and a built-in RM69330 driver IC. So, it is easy to use it as a display replacement for your existing products. It can also be easier to use if you add a capacitive touch panel.

Even when the temperature is under 0°C or above 40°C, it can still work well.
