A035QN05 V4 AUO TFT Display 3.5 inch 320x240 Sunlight Readable

Use A035QN05 V4 as the listed panel reference, then compare the full part number and revision on the label. Send us photos of the old label and connector side. Compare the mounting holes, thickness, connector location and visible opening on both drawings before ordering.

Send us your host model so we can check the required interface, pinout and electrical limits against the exact product documentation. Check the existing backlight supply and enable/dim signals as well. Two connectors that look identical can carry different signals.

Get the native pixel layout first, then try your service menus and startup graphics at that layout before approving the replacement. Compare the actual native timing and display orientation with the old module. Price any cable, firmware and mounting changes before committing to a substitute.

Use the listed 500 cd/m² to shortlist the display, then judge the assembled product with its final cover and ambient lighting. Test cold boot, restart, brightness control and a full diagnostic image. Use the listed −20 °C to +70 °C operating range to plan cold starts and hot running tests, with temperature measured at the panel. Check that the cable clears the frame with the equipment closed.

The listed configuration has no touch. If your design needs it, confirm the overlay, controller and cable as separate items in the quote. Give us the equipment model, approved panel and touch revisions where applicable, quantity and required date. Ask for the quoted revision and how a substitution would be handled.
