3.99” Bar LCD Display 400*960 Industrial Grade Screen

Use the 3.99-inch diagonal to shortlist bar displays, then check the exact drawing for fit. Compare the active width and height, bezel overlap and flex-cable exit with your drawing. Start with the listed 400 × 960 pixel layout. If you mount the long edge horizontally, try a 960 × 400 content layout and verify rotation on the intended host. Keep the panel’s native timing separate from the artwork orientation.

The catalog mentions MIPI and RGB. Send us your host model and ask us to confirm the role and wiring of each connection on the configuration you plan to order. Confirm that the graphics pipeline can render the native mode and map rotation correctly. Test boot graphics and your application with the panel in its installed orientation.

Pick the bar format when the opening and the layout can use its long axis without cropping essential content. Compare the controller and mounting changes against a standard screen, then mock up text at the actual viewing distance. Use the listed 300 cd/m² to shortlist the display, then judge the assembled product with its final cover and ambient lighting.

Check for uneven illumination and cable strain after mounting. Use the listed −20 °C to +70 °C operating range to plan cold starts and hot running tests, with temperature measured at the panel. Test any intended rotation and dimming with the application running.

Send us the panel drawing or label, installed orientation, connector exit and controller model. Include the approved revision, any cover or touch requirement, forecast quantity and required date on the purchase specification.
