QLED
Quantum-dot LED — an LCD panel whose backlight passes through a quantum-dot film that converts blue light into pure red and green, widening color gamut. QLED is still LCD; not to be confused with OLED.
QLED panels use quantum dots — nanoscale semiconductor crystals that emit a precise wavelength when excited — to convert blue backlight into saturated reds and greens. The result is wider color volume than a vanilla LCD.
QLED vs OLED
- Brightness. QLED wins on sustained full-screen brightness; useful in bright rooms.
- Black levels. OLED wins; QLED relies on backlight dimming, which causes blooming.
- Burn-in. QLED has none; OLED has some residual risk.
- Viewing angle. OLED much better; QLED loses contrast off-axis.
QLED vs QD-OLED
QD-OLED uses quantum dots on top of an OLED stack — combining QLED's color volume with OLED's per-pixel contrast. It's the current premium-segment winner where price isn't a constraint.
