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?
The viewing angle is narrower than VA LCDs, so colors shift significantly off-center.
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.
Permanent image retention (burn-in) is more likely when the same content stays on the screen continuously.
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.
