DS40038 FAQ
Can DS40038 drive my existing LCD panel safely?
Listed source inputs include VGA. Listed panel outputs include RGB. Check both ends independently against the source and LCD documentation. Send the complete LCD part number and connector photos. Check the panel supply and pinout, backlight power and enable or dimming signals before applying power.
Will DS40038 give me the resolution and refresh my source needs?
Treat 800 × 480 as the listed maximum supported resolution. Check that the board firmware actually offers your panel’s exact timing and refresh. Check whether the source mode is accepted and whether the LCD will be driven at its native mode. Include the exact source and target mode in your request.
Should I choose DS40038 or a controller already configured for my panel?
Use the full controller part number and revision from the unit label and the corresponding drawing. Compare firmware availability, cable and backlight changes, mounting space and time to validate your panel. A matched board and cable can be easier to reproduce when the same LCD revision will be used in production.
What should pass on a sample of DS40038 with my panel?
Use your actual LCD, source and cable to check startup, a full-screen test image, brightness control and repeated wake. Check cable and regulator temperature during a sustained run.
What should I specify so a repeat order of DS40038 works with the same LCD?
Ask us to record the board revision, programmed firmware, panel part number, cable pinout and power setup on the quote. Keep those references and the approved sample test together when ordering another batch.
