What is QLED technology, unlike oled and led, reviews

What is QLED technology

In fact, QLED - the name of great marketing, rather than reflecting something innovative. At the core, as well as on all TVs with LCD display, backlight technology lies with LEDs. Just realized this is a special way. Generally, QLED term introduced by Samsung as a description of the new method of backlighting screens. At the same time the exact same technology, only from LG, called Nano Cell.

QLED feature lies in the fact that each pixel emits its own color, but does not generate it from mixing several base. Pull it off the transistors, the dimensions of which do not exceed a few nanometers. Despite the breakthrough in QLED there are a number of problems. Firstly, the pixels will still have to highlight. Second, display brightness is gradually reduced after every 10 000 hours.

TVs OLED - what it is on technology

This is a completely new type of light-emitting diodes, which are actively used in the displays. The technology is based on the ability of multilayer films of the polymers under the effect of glow current. In fact, this is the main difference between LED and OLED TVs.

The main advantages of the technology are considered heightened brightness, high contrast and low power consumption. Along with this, there are disadvantages that at this stage there are more deficiencies of the new technology. Firstly, some of the colors lose their brilliance before the other - to create a robust screens until you get it. Secondly, since the technology is new, more noticeable imperfection of it, and therefore it is very expensive to produce.

What is LED Technology

Sheer abbreviation stands for LED light-emitting diode or "light emitting diode". These diodes have become used to the backlight of the liquid crystal matrix screens. Realization is possible in two ways: in the form of strips of diodes on the edges of the screen or in the form of a matrix on the entire screen.

The second approach uses RGB-LEDs to illuminate certain colors. There is also an acronym for WLED, which means "white LEDs", and also looks more like a marketing name. WLED- or LED-screens operate on the same principle.

What is IPS technology

IPS technology - a type of matrix used in the displays. One of its most important advantages - wide viewing angles, which could not boast TN matrix.

IPS also conveys more fully the depth of color. company LG, Hitachi, and NEC constantly improve and develop the IPS. Therefore, there is a whole lot of versions of this technology - with their identification and nuances.

QLED, OLED or LED - which is better?

Comparison of the three types of illumination to perform better on certain criteria. Therefore, we will analyze the differences LED, OLED and LCD-displays QLED in different categories.

Response time

Any dynamic object leaves a trail on the screen, which is formed due to the fact that each pixel should have time to change the color. The smaller the response time (the speed of color change pixel), the smaller the plume, and the picture will look more consistent.

The leader here is undoubtedly the OLED. Since the pixels themselves are a source of color and light, they change almost instantly. RTT in OLED can reach 0.1 ms. QLED inferior in this respect. Since the light pixels in this technology is still being implemented by individual diodes, there are overheads to manage drivers and backlight. LED also remains behind all.

In general, manufacturers of modern televisions are trying to solve these problems additional tweaks and software. So sometimes a quality LED TV can show excellent results, approaching QLED.

QLED contrast, OLED and LED brightness

Compare the brightness of three technologies - it is very subjective. Different models can display different brightness levels to implement, up to software. However, conclusions can be drawn based on the technologies themselves.

OLED can deliver the highest brightness among all presented today highlighting ways. However, the brightness - this is the main criterion for the time display performance. The higher the brightness is, the less it will serve. Therefore, for finding the ideal balance between wear resistance and brightness, it is regulated in such artificially displays. Moreover, OLED-devices give the best contrast and the ratio of white to black can be adjusted by a deeper black.

LED- and QLED-LEDs have little or no difference in brightness. The fact that both types are based on the same mechanism of illumination by the LEDs. Another thing is that TVs QLED simply smarter and use a lot of new technologies for the realization of the brightness enhancement.

According to the contrast and depth of black

These two parameters will be the highest in OLED-TVs. What does it mean? Contrast them virtually endless. This means that the black color of the display looks more real. Due to the fact that each pixel has its own color and light, contrast adjustment for OLED - no problem.

QLED LED and have a much lower contrast. There restricts illumination method itself pixel blocks or segments. Naturally, in the neighboring areas to get a sharp transition from white to black is difficult.

Color gamut

Determine the best color gamut - also not an easy task. Models displays having on board HDR substantially nullify the difference between the natural high color reproduction and realization of it using this technology. For example, QLED-TV on almost all models have a multi-HDR. But OLED-on versions - not everywhere. That is, the color rendition is formed there by natural means, and, indeed, the OLED provides more realistic colors. In conventional LED-models of color reproduction depends on the presence of HDR.

Viewing angles

Most maximum viewing angles - in OLED displays. Since the diodes and in fact constitute the matrix itself, by changing the viewing angle color shift does not occur and the shading of the image. QLED, if they are based on IPS matrices, also show very good results. LED-displays are sometimes still can be implemented on TN matrixes with not the greatest viewing angles.

QLED, OLED or LED - energy efficiency comparison

On average, all three technologies have about the same power consumption. He just spend it a little differently. The OLED-TVs power consumption accounts for each pixel. How much it consumes - it depends on its brightness. The LED-technology all consumption goes to provide illumination. It also includes management controllers, drivers and direct diodes. Smart TVs are a bit lower power consumption depending on the environment at the expense of adaptive brightness setting system. Therefore, all three technologies are not specific differences in energy consumption.

Term QLED service, OLED and LED

The outsider in this category immediately looks OLED. Because of technology costs, the pixels are losing their former brightness for the past 2-3 years. And the more intense brightness, the faster it happens. QLED- and LED-screens (or more precisely, the matrix) can be operated for a long time. The only thing that can bring - electronics and peripherals, providing electrical work or individual components.

What is the result: some steeper technology

There is no doubt that the innovative OLED is superior in many aspects of any of the representatives of the LED-segment, including QLED. However, it is still too fresh and young for general consumers, and therefore has some serious flaws. Should I buy an OLED-TV? Technology does not stand still, grow and move forward. Surely very soon we will get a screen with the image quality, is nearly the same, with the lowest power consumption and low price. In the meantime, we have the other players in the market in addition to the OLED - LCD, IPS, QLED, or LED.
