A 1.75 inch round AMOLED display built around a rotary encoder. Turn the knob to move through a menu, press it to confirm. The AMOLED panel gives 450 cd/m2 typical of brightness and true blacks, so the screen stays readable in daylight and keeps its contrast at wide viewing angles.

The module suits handset and wall-panel products: climate controls, audio systems, home automation and industrial HMI. Resolution is 466 x 466 and the panel is capacitive touch, so the screen also works as a touch key.
