According to CompTIA A+ Core 1 220-1201 objectives under Hardware and Display Technologies:
Mini-LED displays use an array of tiny LEDs as a backlight for LCD panels.
Unlike OLED displays , which are susceptible to burn-in (permanent image retention when static content is displayed for long periods), mini-LEDs reduce the risk because the pixels themselves do not emit light individually and are less prone to permanent image retention.
Why the other options are incorrect:
A. Increased contrast: OLED typically provides better contrast because it can turn off individual pixels completely.
B. No backlight: Mini-LEDs still use a backlight, whereas OLEDs do not.
C. Improved viewing angle: OLEDs generally offer wider viewing angles than mini-LED LCDs.
