    DS20049 FAQ

    Will DS20049 fit my enclosure and show the whole interface?

    Use the 3.92-inch diagonal to shortlist display modules, then check the exact drawing for fit. Overlay the visible area, module outline and flex exit on your enclosure drawing. Try your menus and text on a 320 × 320 canvas before committing to the enclosure.

    What do I need to check before connecting DS20049 to my controller?

    For the listed MCU interface, match the exact bus mode, pin assignments, logic levels and display controller commands. Before connecting it, check the power rails and reset sequence in the module documentation.

    How should I compare DS20049 with a similar screen for my device?

    For the listed LCD, compare viewing-angle shifts and dark-screen appearance through the front cover. Use the listed 400 cd/m² to shortlist the display, then judge the assembled product with its final cover and ambient lighting. Compare the cost and space of any changes to the cable, host board or front cover.

    What should pass before I approve a sample of DS20049?

    Start with repeated power cycles, then test the intended UI through the finished cover. Use the listed −20 °C to +70 °C operating range to plan cold starts and hot running tests, with temperature measured at the panel. If touch is required, confirm the controller, host driver and cover stack for the exact configuration and test edge taps on the sample.

    What should I specify so a repeat order of DS20049 matches my approved sample?

    Use the full display part number and revision from the unit label and the corresponding drawing. Include the drawing revision, flex or connector version and any touch or cover option in the quote. Give us the sample quantity, production quantity and required date so we can confirm the configuration and lead time.
