A menu board needs deep black and a panel that makes its own light per pixel, with no separate backlight. The image changes often. Which panel fits?
Select an answer to reveal the explanation.
Short Explanation
Each pixel should be its own little lamp, so black is a pixel that is off, and there is no backlight behind the panel. You want OLED. A fluorescent lamp, a fast narrow panel, and an analog cable are not that design.
Full Explanation
OLED pixels emit their own light, so the panel needs no separate backlight and can show a deep black by turning pixels off. The menu board asks for that, and the image changes often, which avoids a static picture sitting long enough to burn in. A fluorescent panel uses a backlight and an inverter. It does not make light per pixel, and it does have a separate backlight. Twisted nematic is chosen for response time, not for the deepest black. VGA is an analog connector, not a panel technology. Exam caveat: OLED can still burn in if a logo sits in one place for months. This board's image changes often, which is why OLED fits. Operational check: confirm the panel has no backlight inverter to replace, and confirm black areas stay black from the side the customers will stand. Confirm black areas stay black from where the customers will stand. Note the result on the ticket. Keep logos from sitting in one corner for months so the panel does not ghost.
