LED vs OLED TVs: Which One Should You Buy?

Intro: LED vs OLED TVs

The television market can be quite confusing, with new acronyms and technologies popping up every year. The terms LED and OLED are among the major ones that you will definitely come across when looking for a new TV. Both are capable of showing beautiful images, but though these ways are different, each technology has its own pros and cons. So which one will be the best choice for you? Let's analyze it together.

The Fundamental Difference: How They Light Up

LED TVs (Light Emitting Diode TVs), more precisely called LED-backlit LCD TVs, utilize an LCD (Liquid Crystal Display) panel for image generation. The liquid crystals do not produce light by themselves; they merely act like microscopic shutters, either blocking or permitting light emitted from a separate backlight to reach the observer. The backlight consists of an array of LEDs, which are mounted behind the LCD panel and throughout the entire screen area.

On the contrary, OLED TVs (Organic Light Emitting Diode) have completely different characteristics. In an OLED display, every single pixel is an organic LED that lights up when an electric current flows through it. Hence, there is no requirement for a separate backlight. This basic variation creates OLED's unique properties.

LED vs OLED TVs: Key Differences & What They Mean for You

Black Levels and Contrast

• OLED: OLED TVs are capable of perfect blacks since every single pixel produces its own light and can be completely switched off. This leads to an extremely high contrast ratio; thus, colors look brighter and images appear more like real life. When a particular pixel is turned off, it is completely off, so there is no light bleed at all.

• LED: The LED TVs have better light management with advanced local dimming techniques (with independent dimming or brightening of the LED backlight in different regions), but still do not reach full black. There will be backlight always, and it can show as blooming around a dark background and bright objects.

Brightness: LED vs OLED TVs

• LED: Typically, LED televisions are capable of producing much higher peak brightness than OLED ones. This quality of LED TVs makes them perfect for bright rooms and for presenting HDR (High Dynamic Range) content, where the extreme brightness can reveal details in the highlights.

• OLED: Although OLED has increased its brightness significantly, it's not nearly as bright as the highest-quality LED televisions. But their higher brightness often compensates for the difference, since they can appear as effective as the actual light.

Viewing Angles: LED vs OLED TVs

• OLED: Thanks to self-emissive pixels, OLED TVs offer virtually perfect viewing angles. Colors and contrast remain consistent even when viewed from extreme off-centre positions.

• LED: Viewing angles can vary greatly among LED TVs. Cheaper models often suffer from color shift and contrast degradation when viewed from the side. Higher-end LED TVs, especially those with IPS (In-Plane Switching) panels, offer better viewing angles, but still generally can't match OLED.

Color Accuracy: LED vs OLED TVs

• Both: Both of them have the capability of delivering amazingly vivid and precise color. OLED's flawless blacks increase the color quality, while premium LED TVs usually provide a larger color spectrum due to their increased luminosity capabilities.

Response Time & Motion Handling

• OLED: OLED TVs have an extremely fast response time (often less than 0.1ms) because each pixel can instantly switch on or off. This results in incredibly smooth motion, making them ideal for gaming and fast-paced action movies.

• LED: LED TVs have slower response times than OLED, though modern LED TVs have made significant strides. You might still observe some motion blur in very fast-moving scenes, especially in budget models.

Lifespan and Burn-in

• OLED: In the beginning, OLED TVs faced concerns over "burn-in" which is when static images being displayed for lengthy time periods may leave behind a small and permanent ghost image. Though manufacturers have introduced techniques to reduce the effects of this (pixel changing or dimming logos) but it's still an option, particularly when viewers frequently view video content that has non-moving elements (e.g. news tickers or games HUDs). Also, the lifespan of OLED panels is typically thought to be less than LED.

• LED: LED TVs are not susceptible to burn-in. Their backlights have a very long lifespan.

Price: LED vs OLED TVs

• OLED: Historically, OLED TVs have been significantly more expensive than LED TVs. While prices have come down, they generally still command a premium, especially at larger screen sizes.

• LED: LED TVs are available across a vast price range, from very affordable entry-level models to high-end sets that rival OLED in features and performance (though perhaps not in black levels).

Which One Should You Buy?

Choose OLED if:

• You prioritize picture quality above all else, especially perfect blacks and incredible contrast.

• You often watch movies and TV shows in a dark or dimly lit room.

• You appreciate wide viewing angles, as people often watch from various spots in the room.

• You are a serious gamer who values instant response times and smooth motion.

• You are willing to pay a premium price.

Choose LED if:

• You need a TV for a bright, well-lit room and require high peak brightness.

• You want the best bang for your buck and are looking for a more affordable option, especially at larger sizes.

• You're concerned about potential burn-in due to specific usage patterns (e.g., long gaming sessions with static HUDs, continuous news channel viewing).

• You want a TV that will likely have a longer overall lifespan.

• You want a TV with the absolute brightest HDR highlights.

5 FAQs on LED vs OLED TVs

1. Are issues with "burn-in" still a big problem for OLED TVs?

The risk of burn-in is present, but it's much less of a problem when using modern OLED televisions. There are a variety of technologies that manufacturers use, including shifts in pixel size or logo dimming, as well as the refresh cycle of screens, to prevent the risk of burn-in. In the majority of viewing patterns, burning-in will not happen. 

If you regularly display static images for prolonged time periods (e.g. for example, a news channel with a continuous ticker that runs for more than 8 hours per day, as well as a game that has an unchanging HUD for hundreds of hours) it's something you should be mindful of.

2. Do LED TVs have any benefits in comparison to OLED TVs?

Yes, absolutely! The main benefit of LED TVs is their significant increase in peak brightness, making them ideal for bright spaces and providing impressive HDR highlights. Additionally, they are generally less expensive, and are offered with a wider selection of pricing and aren't susceptible to being burned-in.

3. What is QLED? Does it have the same characteristics as LED or OLED?

The QLED (Quantum Dot LED) is a particular kind of LCD television with LED backlighting. It is most often endorsed by Samsung. Quantum dots are used to increase brightness and color.

It's essentially an improvement of LED technology and not an alternative to OLED, similarly. QLED TVs have the increased brightness of LED and also offer a larger range of colors, which are more vibrant; however, they rely on a light source and are unable to get the exact blacks as OLED.

4. Which TV model will be best to play on?

Both are great to play on; however, OLED generally has a better advantage due to its instant response time and crystal-clear blacks, which offer incredible clarity and detail even in dim gaming scenes. 

But the top LED TVs provide very low input lag as well as a high rate of refresh, which makes excellent gaming monitors, particularly if you want high brightness to play HDR gaming or worry about static HUD components.

5. What is the difference in price between OLED and LED? Is OLED worth the cost?

It's a personal choice and is contingent on your spending and preferences. If you're a fan who values the best picture quality, including high contrast and deep blacks, and you mainly watch television in dark environments and have a dark room, many will say the extra cost of OLED is worth the cost. 

If you're operating on a lower budget, are watching TV in bright rooms, or you're not as sensitive to the perfect black level, a high-end LED TV is able to provide an exceptional quality of viewing for a lower cost.
