A graphic‐design client is upgrading from a conventional LED-backlit IPS monitor because HDR images look washed out in dark scenes. They reject OLED panels due to burn-in concerns, so you recommend a Mini-LED display instead. Which characteristic of Mini-LED technology most directly improves HDR performance compared with the client's current monitor?
Thousands of tiny backlight LEDs provide fine local dimming zones, creating much higher contrast for bright and dark areas.
The technology lowers the refresh-rate demands on the panel, nearly eliminating motion blur.
Each pixel generates its own light, eliminating the need for any backlight.
The LCD layer is replaced with an organic material that yields perfect color reproduction.
Mini-LED panels still use an LCD layer, but the backlight is composed of thousands of very small LEDs divided into many local-dimming zones. Because each zone can be brightened or dimmed independently, the screen can display very bright highlights next to deep blacks, dramatically increasing the effective contrast ratio required for convincing HDR content. Standard LED backlights use far fewer and larger LEDs, so their dimming zones are coarse and cause lower contrast. Mini-LEDs are not self-emissive like OLED, do not change the LCD layer itself, and do not inherently affect motion blur or refresh-rate requirements.
