| Parameter | OLED (WOLED, QD-OLED, MLA-WOLED 2023+) | Mini-LED LCD (Neo-QLED, QNED, Liquid Retina XDR, etc.) |
|---|---|---|
| Native contrast | →∞ (0 nits black) | 3 000-8 000 : 1 panel + local dimming; effective 100 000-1 000 000 : 1 but not per-pixel |
| Peak brightness (10 % window, 2023 panels) | 1 000-2 000 nits (QD-OLED S95C ≈1 500 nits, MLA-OLED G3 ≈2 100 nits) | 1 800-4 000 nits (Samsung QN95C ≈2 000 nits, TCL X11 ≈3 000 nits, Pro Display XDR 1 600 nits sustained) |
| Full-screen brightness | 150-250 nits (ABL limits) | 600-1 000 nits typical |
| Black level uniformity | Perfect; no blooming | Minor to noticeable halo/blooming around high-contrast edges |
| Response time (GtG) | <0.2 ms | 1–5 ms for IPS/VA + scanning backlight |
| Viewing angle | ≈±80 ° with minimal color/luminance shift | ±50 – 70 °; VA panels suffer contrast drop |
| Burn-in / image retention | Possible (cumulative usage × luminance × duty cycle); mitigated by compensation cycles, logo dimming, pixel shift | None (same as conventional LCD) |
| Panel life | Blue sub-pixel decay dominates; 30 000–100 000 h depending on luminance | 60 000–100 000 h backlight; LC cell not wear-limited |
| Thickness / flexibility | 1–3 mm glass or even rollable | 8–25 mm (backlight + light guide) |
| Power (mixed SDR) | 80-200 W for 65″, proportional to Average Picture Level (APL) | 120-300 W for 65″; higher at HDR white |
| Manufacturing cost (65″ 4 K) | ~$600 panel BOM (2023) | ~$350 panel BOM |
| Environmental factors | Fewer layers, but organic materials, NMP solvent use | More optical sheets, higher plastics/aluminium usage |
Typical performance observations
• Blooming: Stars on a night sky exhibit halos on Mini-LED unless dimming-zone density approaches pixel pitch; OLED shows none.
• HDR specular highlights: Mini-LED’s 2-4 k nits produce “pop” in sun reflections, fireworks. OLED’s highlight may clip earlier but retains shadow detail simultaneously.
• Motion: OLED’s near-instant response eliminates sample-and-hold blur; Mini-LED LCD relies on black-frame insertion or 240 Hz to approach the same clarity.
• Uniformity: OLED sometimes shows slight pink/green tint on near-black; Mini-LED can show dirty-screen effect or dimming-zone transitions on pan shots.
Implementation quality matters
– A budget Mini-LED with 240 zones can look worse than a premium OLED; a flagship Mini-LED with 5 000 zones and sophisticated algorithms can approach OLED shadow rendition.
– QD-OLED (Samsung Display) replaces the color-filter stack with quantum-dot conversion, boosting brightness and color volume vs. white-OLED.
– MLA-(Micro Lens Array)-OLED (LG G3/G4) increases luminance efficiency ~60 % by collimating light through micro-lenses.
• 2023-24: Samsung S95C/S90C QD-OLED, LG G3 MLA-WOLED, TCL QM8 and Samsung QN90C Mini-LED are reference implementations.
• Zone counts are climbing (>5 000) and driving ICs now use 16-bit PWM+analog hybrid dimming to reduce banding.
• LG Display’s 3rd-gen Meta-OLED and Samsung’s 3rd-gen QD-OLED panels (2024) target 3 000 nits peak, narrowing the brightness gap.
• Mini-LED enters tablets/laptops (iPad Pro 12.9, MacBook Pro, Asus ROG PG27AQDM) giving HDR on portable form factors.
• Micro-LED (separate µ-sized inorganic RGB emitters per pixel) is progressing but still >$3 000 per 55″ module.
• Why OLED blacks are “perfect”: LC shutters in LCDs leak ~0.05-1 % of backlight even when “closed”; OLED drives current to zero.
• Why brightness is limited on OLED: Self-heating accelerates organic degradation; panel uses an Automatic Brightness Limiter (ABL) to protect lifetime and PSU.
• Why blooming happens: A star occupies maybe 4×4 pixels; if the mini-LED zone is 32×32 pixels, the backlight lights 64× the needed area.
• Burn-in mechanism: Cumulative exciton-induced degradation of emissive layers, most aggressively in blue OLED material.
• Energy regulations (EU EcoDesign, US DOE) impose maximum on-mode power; Mini-LED sets may require dynamic power limiting to comply in HDR test modes.
• Recycling: OLED panels currently lack a scalable recycling chain for organic emissive layers; Mini-LED backlights add millions of tiny LEDs that complicate disassembly.
• Health & safety: High-brightness Mini-LED monitors can exceed 1 000 cd/m²; IEC 62471 photobiological safety Group 1 limits must be observed (blue-light hazard).
Potential challenges & mitigation
• Blooming: pick models with >1 000 zones and test “starfield” patterns; use low local-dimming aggressiveness settings.
• Burn-in: enable logo luminance adjustment, schedule pixel refresh, avoid >200 nits average level on static OSDs, rotate content.
• All brightness figures are for 10 % windows; full-field values are much lower for OLED and only moderately lower for Mini-LED.
• Real-world viewing distance and ambient light often reduce perceivable contrast differences.
• Panel lottery: sample-to-sample uniformity varies; consult measured reviews.
• Evaluate electroluminescent quantum-dot (ELQD) progress, combining inorganic emissive quantum dots with per-pixel drive (possible OLED successor).
• Follow development of TADF-blue OLED emitters to extend OLED lifetime and brightness.
• Study novel backplane drivers (LTPO, Oxide TFT) that allow variable refresh + lower idle power.
• Investigate AI-based local-dimming algorithms to minimise blooming without latency penalties.
OLED delivers unmatched black level, contrast, response time, and form-factor flexibility, ideally suited to controlled-light environments and image-critical workloads but with burn-in and brightness limitations. Mini-LED augments LCDs with thousands of backlight zones to achieve superior peak luminance, robust HDR, and immunity to burn-in at a friendlier cost, yet it cannot fully eradicate blooming nor equal OLED’s off-axis or black-frame performance. Match the technology to your ambient light, content mix, long-term usage pattern, and budget to obtain the optimal viewing experience.
