OLED or Mini-LED is the biggest decision you make when buying a premium TV, and it is a choice between two genuinely different ways of making a picture. It is not a question of one being newer or better. Each has a strength the other cannot match, and each has a weakness worth understanding before you spend $1,000 or more.
This guide explains how the two technologies work, what that means for contrast, brightness and burn-in, and then compares OLED and Mini-LED TVs from our catalog at the same prices. Every spec, price and Mars Score below comes from our catalog; the Mars Score is the live, formula-computed value described in how we score products.
The short answer
- You watch mostly in the evening, in a room you can darken: OLED. Per-pixel light control gives perfect blacks and no halo around bright objects.
- Your TV faces windows or you watch mostly in daylight: Mini-LED. It sustains high brightness across the whole screen more easily than OLED.
- You leave news channels, sports tickers or game HUDs on screen for hours every day: Mini-LED, because it cannot burn in. OLED is a reasonable choice for most mixed viewing, but static content for long periods is the use case where its risk is real.
- You want the most picture per dollar: Mini-LED. In our catalog, the highest-scoring 65-inch Mini-LED TV costs about half as much as the highest-scoring 65-inch OLED.
How the two technologies work
OLED: every pixel is its own light
In an OLED (organic light-emitting diode) panel, each pixel produces its own light. To show black, a pixel simply switches off. That is why OLED has effectively infinite contrast: a star against a black sky is one lit pixel next to unlit ones, with no light spilling around it.
There are two main OLED families in our catalog. WOLED, used by LG, Panasonic, Philips and in some Sony models, uses white sub-pixels with colour filters. QD-OLED, used by Samsung and in some Sony models, uses a blue OLED layer with quantum dots to create red and green. Both are self-emissive and share OLED's core strengths and its core weakness; in our catalog they are recorded separately as "OLED" and "QD-OLED".
Mini-LED: a better backlight behind an LCD
A Mini-LED TV is an LCD TV. The picture is formed by a liquid-crystal layer, and the light comes from a backlight behind it. What makes it "Mini-LED" is that the backlight is made of thousands of very small LEDs grouped into local dimming zones that can be brightened or dimmed independently.
The more zones, the more precisely the TV can keep dark parts of the picture dark while lighting bright parts. But there are always far fewer zones than pixels. When a small bright object sits on a dark background, the zone behind it lights up an area larger than the object, and you can see a faint glow around it. This is called blooming, and it is the main picture-quality compromise of Mini-LED. Good processing keeps it subtle; it never disappears entirely.
Contrast: OLED wins, and it is not close
Because OLED switches individual pixels off, it shows true black and no blooming in any scene. Mini-LED has made huge progress, and a well-tuned set in a bright room looks superb, but in a dark room with dark content — space scenes, night-time films, subtitles over black — OLED's advantage is visible.
Viewing angle follows the same logic. OLED holds its contrast and colour well off-axis. Many Mini-LED TVs use VA-type LCD panels, which have high native contrast straight on but lose some of it at wide angles. If your seating is spread out across a wide room, this is worth weighing.
Brightness: Mini-LED's advantage is sustained, full-screen light
The peak brightness figures in our catalog are manufacturer-listed values, and both technologies now list very high numbers. Our highest OLED figures are 4,000 nits on the LG G5 OLED evo 65 and 3,800 nits on the Samsung S95F QD-OLED 65. Our highest Mini-LED figures are 5,000 nits on the Hisense U9Q Mini LED 65 and TCL QM851 Mini LED 65.
What those headline figures do not show is how much of the screen can be that bright at once. Peak brightness is usually quoted for a small highlight — a reflection, a lamp, the sun in a scene. OLED TVs use an automatic brightness limiter (ABL) that lowers brightness when a large part of the screen is bright, to manage power and heat. A full-screen bright image — a snowy landscape, a hockey rink, a white web page — is therefore noticeably dimmer on OLED than its peak figure suggests. Mini-LED backlights can sustain high brightness over much larger areas.
In practice: in a dark room, both technologies are more than bright enough. In a sunlit room, Mini-LED stays punchier, and it is the safer choice if glare and daylight are your main problem.
Brightness also varies a lot within each technology. The cheapest OLED in our 65-inch set, the LG B5 OLED 65, lists 750 nits — a fifth of the G5's figure. Do not assume every OLED is as bright as the flagships.
Burn-in: what it is, and how worried to be
Burn-in (strictly, permanent image retention) is the reason most people hesitate over OLED, so it is worth being precise about it.
What causes it
OLED pixels are made of organic materials that dim slowly with use. If some pixels are lit far more than others for very long periods — a channel logo in the same corner, a news ticker, a game's health bar, a desktop taskbar — those pixels age faster than their neighbours. Eventually a faint ghost of the static element can remain visible on uniform backgrounds. The effect is cumulative and not reversible.
What the TVs do about it
Modern OLED TVs include several protections by design: pixel shifting, which moves the image by a few pixels over time; logo detection and dimming, which lowers brightness on static elements; and compensation cycles that run while the TV is in standby to even out pixel wear. These are why you should let an OLED TV go into standby normally rather than cutting power at the wall.
Who is actually at risk
For varied viewing — films, series, streaming, a mix of channels and games — burn-in is unlikely to be a practical problem with a modern OLED TV. The risk rises with the same static content, at high brightness, for many hours a day, day after day: a 24-hour news channel left on in the background, a single game with a fixed HUD played for hours daily, or using the TV as a computer monitor with a fixed taskbar.
Mini-LED TVs, being LCDs, do not burn in in this way. If your viewing matches the high-risk pattern above, that alone is a strong reason to choose Mini-LED. If you buy OLED, check the manufacturer's warranty terms on burn-in, since they vary.
Gaming
Both technologies are excellent for gaming. OLED's near-instant pixel response gives very clear motion. Every OLED and Mini-LED TV in the comparisons below supports VRR and ALLM. One practical difference in our catalog is HDMI 2.1 port count: LG, Samsung and Panasonic TVs here list four, while most Sony, TCL and Hisense sets list two. If you connect a console, a PC and a soundbar, count your ports. Our best game consoles guide covers the other half of that setup.
Matchups at the same price
All prices are 65-inch MSRPs from our catalog.
Flagship: Samsung S95F QD-OLED vs Hisense U9Q Mini LED
Full side-by-side: Samsung S95F QD-OLED 65 vs Hisense U9Q Mini LED 65.
The Samsung S95F QD-OLED 65, Mars Score 82.4 at $3,299, is the highest-scoring 65-inch TV in our catalog. The Hisense U9Q Mini LED 65, Mars Score 77.7 at $1,799, is the highest-scoring 65-inch Mini-LED. Both list 165 Hz. The Hisense lists higher peak brightness (5,000 vs 3,800 nits) and supports both Dolby Vision and HDR10+; the Samsung supports HDR10+ only, but has four HDMI 2.1 ports to the Hisense's two.
Verdict: the S95F for a dark room and the best contrast you can buy. The U9Q for a bright room — and it saves $1,500.
The LG alternative: LG G5 OLED evo 65 vs Hisense U9Q Mini LED 65. The LG G5 (Mars Score 80.4, $3,399) adds Dolby Vision to the OLED side.
Upper mid-range: LG C5 OLED vs TCL QM851 Mini LED
Full side-by-side: LG C5 OLED 65 vs TCL QM851 Mini LED 65.
The LG C5 OLED 65 (Mars Score 69.0, $2,499) is the OLED most people shortlist. The TCL QM851 Mini LED 65 (Mars Score 76.2, $1,499) is $1,000 cheaper and scores higher. The TCL lists 5,000 nits against the C5's 1,300, supports HDR10+ alongside Dolby Vision, and runs at 144 Hz like the C5. The C5 has four HDMI 2.1 ports to the TCL's two.
Verdict: on our spec sheet, the TCL is the stronger buy. Choose the C5 if your room is dark, you value perfect blacks and no blooming above brightness, or you need four HDMI 2.1 ports.
Value: LG B5 OLED vs TCL C855 Mini LED
Full side-by-side: LG B5 OLED 65 vs TCL C855 Mini LED 65.
The LG B5 OLED 65 (Mars Score 65.0, $1,699) is the cheapest 65-inch OLED in our catalog. The TCL C855 Mini LED 65 (Mars Score 74.3, $1,199) costs $500 less and lists 3,500 nits against 750, and 144 Hz against 120.
Verdict: the TCL, unless OLED's contrast in a dark room is the specific thing you are paying for. The B5 is the way into OLED; it is not the way to the most TV for the money.
Same brand, both technologies: Sony Bravia 8 II vs Bravia 9
Full side-by-side: Sony Bravia 8 II OLED 65 vs Sony Bravia 9 Mini LED 65.
Sony sells both technologies at the top of its range, which makes this the cleanest like-for-like comparison. The Bravia 8 II (QD-OLED, Mars Score 72.9, $2,799) and the Bravia 9 (Mini-LED, Mars Score 69.5, $3,499) share Google TV, Dolby Vision, 120 Hz and two HDMI 2.1 ports. The Bravia 9 lists 2,700 nits to the Bravia 8 II's 2,100 and costs $700 more.
Verdict: the Bravia 8 II for most rooms. The Bravia 9 makes sense only if your room is very bright or your viewing matches the burn-in risk pattern above.
How to decide, in four questions
- How bright is your room when you watch? Mostly dark: OLED. Mostly daylight or facing windows: Mini-LED.
- Do you leave static content on screen for hours every day? If yes, Mini-LED removes the burn-in question entirely.
- What is your budget for 65 inches? Under $1,500, the strongest-scoring options in our catalog are Mini-LED. OLED starts at $1,699 for the LG B5.
- How many HDMI 2.1 devices do you have? If more than two, check port counts — LG, Samsung and Panasonic list four.
