Which Technology to Choose for Your Next TV?

In the dynamic display technology landscape, two players dominate the market: OLED and LED. These acronyms represent distinct worlds of display engineering, each with its own benefits and challenges. Let’s dive into a detailed OLED vs LED comparison to enlighten consumers on which choice would best suit their smart TV.

What is OLED?

OLED, or “organic light-emitting diode,” represents the cutting edge of display technology. In an OLED TV, each pixel produces its own light when electrified, eliminating the need for a backlight. This allows OLED displays to be extremely thin and flexible, and they can reach absolute black completely turning off individual pixels. LG Display is currently the leading manufacturer of OLED panels, supplying companies like Samsung and Sony.

What is LED?

LED displays, on the other hand, are actually LCDs enhanced with light-emitting diodes. Unlike OLED displays, LED displays rely ona backlight to illuminate the pixels LCD. LED technology has been refined over time, moving from less efficient CCFL bulbs to smaller, brighter, more energy-efficient diodes.

OLED vs LED: comparison of technologies

Image quality and black levels

When it comes to producing deep blacks, OLED is unmatched. Its ability to completely turn off pixels gives theOLED infinite contrast ratio. A crucial point for superior image quality. LED televisions, although improved with technologies such as local dimming, cannot compete with OLED on this criterion due to the very nature of their backlighting.


Televisions LEDs traditionally have an advantage in terms of brightness. Their ability to use powerful, large LEDs allows for better performance in well-lit environments. Improvements in OLED displays also allow them to achieve adequate brightness levels for most situations, but LEDs maintain an advantage in very bright rooms.


When it comes to color reproduction, OLED displays were once the undisputed champions, but the introduction of quantum dots in LED TVs, known as QLED, has dramatically improved color accuracy, brightness and volume LED screens. This puts both technologies on an equal footing in terms of color gamut and accuracy.

Viewing angle

L’OLED offers superior viewing angles, with little degradation in image quality, even at extreme angles. LED displays can suffer from a loss of color fidelity and contrast when viewed off-center. However, anti-reflective coatings have brought improvements.

Longevity and energy consumption

The longevity of the two technologies is comparable, with a slight lead for OLED in terms of lifespan. However, OLED displays may be prone to burn-in, although this is rare under normal use. In terms of power consumption, OLED is more efficient because each pixel lights up independently, while LEDs require constant backlighting.

Health Considerations

Exposure to blue light is a growing concern, and OLED produces less blue light than LED screens, which could be a benefit for long-term eye health.

Size and price

LED displays offer a wider range of sizes and generally lower prices, making the technology more accessible. OLEDs, on the other hand, tend to be more expensive, although prices have fallen in recent years.

OLED vs LED: The new Q-contenders

QLEDs are LED displays enhanced with a layer of quantum dots that improve brightness and color. QD-OLEDs, a recent hybrid, combine quantum dots with OLED to try to offer the best of both worlds: the color and brightness of QLED with the blacks and viewing angles of OLED.

OLED vs LED: conclusion

Ultimately, the decision between OLED and LED will depend on several factors, including viewing environment, budget, personal preferences for image quality and durability. OLED is preferred for its superior image quality, including deep blacks and wide viewing angles. LED displays, on the other hand, offer a more affordable and versatile solution, with superior brightness and a wide variety of sizes.
