Catalog
Round LCD and AMOLED Displays
Round displays put the interface at the center of a dial, controller, clock, or compact instrument. This collection includes the catalog’s circular TFT LCD, touch LCD, and AMOLED modules; compare the technology and specifications of each model separately.

What to check before choosing a module
Start with the visible circle and the enclosure opening, then check the full module outline and FPC exit. A matching nominal screen size does not establish mechanical or electrical compatibility.
- Check which parts of the interface remain visible inside the circular opening.
- Match the listed interface, driver requirements, and resolution to the host processor.
- For touch designs, confirm the cover lens, sensor outline, and usable touch area together.
