4 inch Circular TFT LCD Display 720*720 MIPI

Use the 4-inch diagonal to shortlist round displays, then check the exact drawing for fit. Make a mask from the active circle and bezel drawing. Try your dial, long labels and controls with the mask applied on a 720 × 720 canvas before committing to the enclosure.

For the listed MIPI interface, match the display lane count, lane mapping, operating mode and panel initialization sequence. Check orientation and any address-window offsets in the initialization code, then show a marked test grid to verify the center and edge alignment.

Compare the visible arc, text clipping, module clearance and flex routing for both approaches. Use the listed 250 cd/m² to shortlist the display, then judge the assembled product with its final cover and ambient lighting. A mock-up with your longest labels will show how much of the nominal screen you can actually use.

Check that the artwork and bezel remain concentric, the outer text stays visible and the flex is clear of the mount. If touch is required, confirm the controller, host driver and cover stack for the exact configuration and test edge taps on the sample.

Send us the approved module and bezel drawings, flex position and any touch or cover version. Save the orientation and initialization settings alongside the sample revision and quote reference.
