OLED vs Mini-LED comes down to where the light comes from. OLED pixels make their own light and can switch fully off for deep black. Mini-LED is an LCD with a backlight split into many dimming zones. It can get very bright, but light can bloom around bright objects on dark backgrounds.
OLED and Mini-LED are the two premium screen types you will see on monitors, laptops and TVs. They get to good contrast in opposite ways.
Here is how each works, and what our OLED and LCD screens list. Specs are from each maker’s official page, as of November 2026.
How OLED works
Short answer: each OLED pixel makes its own light. LG calls this self-emissive. A pixel showing black simply turns off, so black areas stay truly dark, even next to something bright.
That per-pixel control is why OLED contrast numbers are so large. LG lists 1,500,000:1 for the LG UltraGear 27GS95QE. Dell lists 1,500:1 for the IPS Dell S2725QC. That is a 1,000x gap on paper.
How Mini-LED works
Short answer: Mini-LED is still an LCD. LG describes it as a backlighting technology: many tiny LEDs sit behind the panel in groups called dimming zones. Smaller LEDs mean more zones, and more zones mean finer control.
Apple gives real numbers for its iPad Pro display. It uses over 10,000 mini-LEDs, grouped into over 2,500 local dimming zones. Apple also notes a slight blooming effect, because each zone is larger than an LCD pixel.
Our zone math: if a 1440p screen had 2,500 zones, each zone would light about 1,475 pixels at once. An OLED at 1440p controls all 3,686,400 pixels one by one.
Mini-LED wins on brightness. OLED wins on black. Pick the one that matches your room.
Which one should you pick?
Short answer: choose OLED for dark rooms, games and movies with deep shadows. Choose Mini-LED for bright rooms and HDR highlights, where Samsung points to brightness as its strength. Standard LCD is the lower-contrast option of the three.
Our catalog has no product that names Mini-LED in its official specs yet. Here is how our OLED and standard LCD screens compare on the numbers their makers list:

Makers measure listed brightness in different ways, so treat that column as a rough guide. For the badges, read DisplayHDR explained. For picks, see best monitors for PS5 and PC.

FAQ
Is Mini-LED a type of OLED?
No, LG describes Mini-LED as a backlighting technology for LCD panels, while OLED is self-emissive.
What is blooming?
It is a faint halo around bright objects on a dark background, which Apple says can happen because LED zones are larger than the LCD pixels.
Which is better for a bright room?
Samsung points to Mini-LED's brightness as its strength, so it tends to suit bright rooms better than OLED.
Do any of your products use Mini-LED?
None of the products in our catalog name Mini-LED in their official specs as of November 2026, so we compare OLED with standard LCD screens here.
