QLED and OLED. Although their names are similar, but different technologies.

QLED, in short, (Quantum Dot Light Emitting Diodes, Quantum Dot Light Emitting diode) is a created by samsung trademark, is used to describe its high-end Quantum dots LED TV series, hisense, TCL, some products are also using the technology of these products by QLED alliance used with permission.

OLED (Organic Light - Emitting Diode, Organic Light Emitting Diode) is a little similar to the QLED from some angles, because it is based on the LED screen, but its internal composition have differences, QLED used in television is the LED panel Light quantum dots, and OLED TV is made up of millions of independent Organic light-emitting diodes (oleds).

Here is more information about the QLED and OLED:

What is the QLED?

In simple terms, QLED is LED TV (don't be confused with OLED TV), they are using quantum dots technology to improve the key image display quality. Can provide better brightness and wider chromatography. This is because when applied in the LED backlight, almost like filters, the quantum dots to produce more pure than the LED light.

QLED is not a spontaneous light screen technology, because quantum dots are not directly send the color you see, they distribute on a ACTS as a color filter diaphragm.

When the screen is opened, the LED backlight irradiation on the diaphragm, so as to refine the light to the ideal color temperature. However, due to the QLED not light, so light LED backlight of the screen in an open position all the time, which means that they are difficult to provide as pure black OLED.

OLED is what?

OLED on behalf of the organic light-emitting diodes (oleds). OLED TV is made up of millions of OLED, the OLED as a single pixel form, each pixel separate light when electricity, so called the self-luminous displays.

For this reason, when a single OLED pixels are not power supply, it will be shut down, look at this time is completely black, just like the television was turned off, so that can show more pure black. Although QLED TV could do a very thin, but OLED TV can do much thinner. In addition, flexible OLED screen easier.

QLED VS OLED

What about QLED and OLED is better or weak, through the brightness, contrast, under the detailed contrast visual Angle, etc.

Black display level

Display shows the ability of black arguably one of the most important factor is to achieve excellent image quality, a more pure black can get higher contrast and more rich color, on display more pure black, OLED is the undisputed champion.

OLED TV if a pixel no electricity, it won't produce any light, so will display a completely black.

And QLED TV behind the quantum dot filling layer using LED backlighting, by offering higher brightness and wider chromatography, using software to dim don't need to open the pixels. This will trigger a called "light-leaking" problem, that is to say, the light will spill over into should display part of black, this is the human eye can distinguish, will affect experience to a certain extent.

Samsung is spending a lot of time and money to improve the QLED TV shows the ability of black, launched a new reflector technology, to improve this problem, so expect this can bridge the gap between QLED and OLED in real black. For now, however, OLED is still showing the black king.

Advantage: OLED

brightness

As propaganda by samsung, QLED TV have considerable advantages in terms of brightness. This depends not only on the software, mainly because of quantum dots can in the case of no loss of saturation and brighter by chromatography is tonal, the in the room with a large amount of ambient light is particularly important.

QLED TV was also thought to be more suitable for viewing HDR content, because the image of the spectrum highlights more visible light, such as a lake or reflected light car paint. That there are still some controversy, however, some people think that OLED display pure black for HDR content better.

Advantage: QLED

Color gamut

OLED has beat all the competitors in this segment, but according to samsung claims that the use of quantum dots, QLED TV in the accuracy of color, color brightness and colour capacity are improved, under the extreme brightness levels with a wider, more saturated colors.

Although there is no denying that QLED can provide excellent colour display, but high brightness levels of saturated colors in the normal watch better doesn't provide too much advantage, so in this round draw.

A draw

Response time and input delays

Response time refers to each diode from "open" to "off" time required. The less the faster response time, motion blur, pseudo like less. Believe that you already know the OLED TV contains millions of single diode, each switch are independent of each other.

In QLED TV, arrange clusters and light-emitting diode, so you can't switch single diode, which leads to "on" and "off" state between the overall slow down. OLED is in short, all in TV technology has the fastest response time, make its become clear winners in this respect, more suitable for playing games, watching sporting events.

Advantage: OLED

Viewing Angle

OLED has once again become a winner. QLED screen the best Angle of view is right in the middle, both color, contrast and image quality will gradually reduce decreases as the Angle of view. Although the extent of the difference between different products, but can be perceived by user.

The OLED screen can be as high as 84 degrees under the visual Angle of brightness reduce won't happen. Although some QLED TV have improved in terms of perspective, but OLED still has obvious advantages. Therefore, if you are demanding visual Angle, the OLED TV is more suitable for you.

Advantage: OLED

size

OLED has a great progress in this aspect, when the technology is still in its early stages, the biggest size is 55 inches OLED screen. Today, you can buy a 88 - inch OLED TV.

But in terms of size, QLED display almost no restrictions on the size, some the size of the QLED TV can reach 100 inches or more.

Advantage: QLED

burn-in

When static images displayed picture for a long time, the image on the screen will leave "echo". Use the word "burn-in" is not accurate, is just a display effect of degradation. If you use a pixel for a long time, it makes it prematurely aging dimmed, under the comparison of pixels, create the impression of a darker.

For most people, the impact of this problem is not big. If you tell a the outcome, then QLED is a winner, more not easy ageing.

Advantage: QLED

The energy consumption

OLED panel is very thin, and don't need a backlight. Therefore, the weight of the OLED TV often lighter than TV QLED, also need less energy consumption, higher efficiency.

Advantage: OLED

price

Once upon a time, QLED TV can easily win this link, but OLED TV prices have fallen, and because we discuss here are high-end products, so can rival QLED TV also with OLED TV roughly the same price, so this link is a draw.

A draw

Conclusion:

QLED in brightness, size and service life has many advantages, and the latest technology to make it show black levels and also improved visual Angle, QLED TV line during the day can provide better display effect, cost performance is also higher.

However, in terms of image quality, and OLED is a winner, OLED TV can provide better visual Angle, more pure black display, better contrast, lighter and thinner at the same time, use less energy consumption, has a better display effect during the night.
