OLED vs QD-OLED: which premium display technology is right for you?
LG's white subpixel vs Samsung's quantum dot layer.
Traditional WOLED panels from LG Display use a white OLED emitter with color filters to produce RGB. QD-OLED from Samsung Display uses blue OLED emitters with a quantum dot conversion layer for red and green, skipping the color filter entirely. The result: QD-OLED delivers wider color volume at high brightness and cleaner whites, while WOLED has deeper blacks in bright rooms and a longer track record for burn-in resistance.

Side-by-side specs
| Spec | OLED (WOLED) | QD-OLED |
|---|---|---|
| Emitter type | White OLED + color filter | Blue OLED + quantum dots |
| Color volume (BT.2020) | ~75% | ~90% (better on this spec) |
| Peak brightness (2% window) | 800-1,200 nits | 1,000-1,500 nits (better on this spec) |
| Black level in ambient light | Deeper (polarizer) (better on this spec) | Slightly raised |
| Burn-in maturity | 10+ years refined (better on this spec) | 2nd-gen improving |
| Best environment | Mixed use, bright room | Dark room, HDR content |
How they differ
Both are self-emissive with per-pixel lighting and true blacks. The key differences: QD-OLED achieves roughly 90% BT.2020 color coverage vs WOLED's ~75%. Peak brightness on QD-OLED hits 1,000-1,500 nits in a 2-3% window vs 800-1,200 nits on WOLED. But WOLED maintains deeper blacks in ambient light because QD-OLED's lack of a polarizer means ambient light can raise black levels slightly, giving blacks a greyish tint in bright rooms. Burn-in: WOLED has 10+ years of refinement and pixel-shift algorithms. QD-OLED is newer but Samsung's 2nd-gen panels show dramatically improved longevity in accelerated tests. For PC desktop use with static UI elements, WOLED is the safer choice. For movies and gaming in a dark room, QD-OLED wins on color and brightness.
Verdict
QD-OLED for cinephiles and HDR gamers who watch in dark rooms and want the widest color gamut. WOLED for mixed-use setups with desktop work and bright-room viewing where deeper blacks in ambient light matter more than peak color volume.
Check your contrast ratiosWhich should you pick?
Choose OLED (WOLED)
Mixed-use PC setups with static desktop elements. Bright rooms where polarizer-backed blacks matter. Proven burn-in mitigation with 10+ years of panel refinement.
Choose QD-OLED
Dedicated gaming and movie setups in light-controlled rooms. HDR content where color volume and peak brightness are the priority. You want the widest color gamut available in a consumer display.
