Your company plans to install a 55-inch panel that will display the company logo on a lobby wall 24 hours a day. The purchasing manager is considering an OLED screen because of its excellent black levels. As the IT technician, you are asked to point out any technology-specific drawbacks. Which factor could make OLED a poor choice for this application?
Permanent image retention (burn-in) is more likely when the same content stays on the screen continuously.
Their contrast ratio is lower than that of traditional TN LCDs, so dark scenes look washed out.
OLED panels require a high-voltage inverter to power a cold-cathode backlight, adding failure points.
The viewing angle is narrower than VA LCDs, so colors shift significantly off-center.
OLED pixels generate their own light, so a static image can unevenly age sub-pixels and leave a permanent ghost image (burn-in). LCDs use a separate backlight, so while image persistence can occur it is usually temporary and far less severe. OLEDs do not need a high-voltage inverter, have a much higher contrast ratio than TN LCD panels, and maintain very wide viewing angles-so those statements are incorrect.
