What is the difference between QLED and OLED TV?

In short, QLED (Quantum Dot Light Emitting Diodes) is a trademark created by samsung to describe its high-end Quantum Dot LED TV series, which is also used by hisense and TCL products that are licensed through the QLED alliance.

In some ways, Organic light-emitting Diode (OLED) is similar to QLED in that it is also based on an LED screen, but its internal composition is different: a QLED TV USES quantum dots illuminated by an LED panel, while an OLED TV consists of millions of individual OLED devices.

QLED vs. OLED

Then QLED and OLED which is stronger or weaker, the following through brightness, contrast, visual Angle and other aspects of the detailed comparison.

Black Display Level

The ability of displays to display black is arguably one of the most important factors in achieving good image quality. Purer blacks yield higher contrast and richer colors, and OLED is the undisputed champion for purer blacks.

If a pixel on an OLED TV is not powered up, it will not produce any light and will therefore appear completely black.

The QLED TV USES LED backlight behind the quantum dot filler to provide higher brightness and a wider spectrum, and USES software to dim pixels that don't need to be turned on. This can trigger a problem called "light leakage," which means that light can spill over into areas that should be black, which the human eye can tell, and which can affect the viewing experience to some extent.

Samsung is investing a lot of time and money in improving the ability of QLED TVS to display black, introducing a new anti-reflective layer technology that is said to improve the problem, so it is expected that this will narrow the gap between QLED and OLED in real black. For now, however, OLED is still the king of black.

Winner: OLED

Brightness


As samsung claims, QLED TVS have considerable advantages in terms of brightness. This depends not just on the software, but mainly because quantum dots can achieve brighter hues in the spectrum without losing saturation, which is especially important in a room with a lot of ambient light.

QLED TVS are also thought to be better suited for viewing HDR content because the spectral highlights in the image are brighter and more visible, such as the light reflected by a lake or car paint. However, there is some controversy over this, with some arguing that OLED displays of pure black are better for HDR content.

Winner: QLED

Color Gamut


OLED has beaten all competitors in this area, but according to samsung, the use of quantum dots in QLED TVS has improved its color accuracy, brightness and color capacity, giving it a wider, more saturated color range at extreme brightness levels.

Although it is undeniable that QLED can provide excellent color display, better saturated color at high brightness level does not provide much advantage in normal viewing, so it is a tie in this round.

Winner: tie

Response time and input latency


Response time is the time required for each diode to change from "on" to "off". The faster the response time, the less motion blur, and the fewer artifacts. You already know that OLED TVS contain millions of individual diodes, each with its own switch.

In a QLED TV, the diodes are arranged in clusters and emit light, so you cannot turn a single diode on or off, resulting in an overall slowdown between the "on" and "off" states. Overall, OLED currently has the fastest response time of any TV technology, making it a clear winner in this area and more suitable for playing games and watching sporting events.

Winner: OLED

Visual Angle


OLED is the winner again. The best visual angle for QLED screen is center, no matter the color, contrast or image quality will gradually decrease as thevisual angle gets larger. Although the severity varies from product to product, it can be perceived by the user.

OLED screens can be viewed at up to 84 degrees without dimming. Although some QLED TVS offer improved visual angles, oleds still have significant advantages. So if you have a high visual angle, an OLED TV is better for you.

Winner: OLED

Size


OLED screens have come a long way in this regard, reaching a maximum size of 55 inches when the technology was still in its early stages. Today, you can buy an 88-inch OLED TV.

But in terms of size, there is little limit to the size of QLED displays, and some QLED TVS can reach 100 inches or more.

Winner: QLED

Screen Burn-in


When a still image is displayed for a long time, it leaves a "shadow" on the screen. The word "screen burn-in" is not accurate; it's just a degradation of the display. If you use a pixel for a long time, it will prematurely age and darken, creating a dark impression in comparison to other pixels.

For most people, the problem doesn't matter much. If there must be a winner, then QLED is the winner, not easy to aging.

Winner: QLED

Energy Consumption


The OLED panel is very thin and requires no backlighting. As a result, OLED TVS tend to be lighter than QLED TVS, require less energy and are more efficient.

Winner: OLED

Price


Once upon a time, QLED TVS could easily win this segment, but OLED TV prices have come down, and since we're talking about high-end products here, comparable QLED TVS are priced at roughly the same price as OLED TVS, so this segment is a tie.

Winner: tie

Conclusion:


QLED has many advantages in brightness, size and service life. In addition, the latest technology has improved the level and visual Angle of black display. QLED TV can provide better display effect in daytime line, and it is also more cost-effective.

In terms of image quality, however, OLED is the winner, offering better viewing angles, a purer black display, better contrast, lighter, thinner, less energy-hungry and better display at night.
