[PConline gossip] said to the display panel, almost everyone will think of LCD and OLED, the former is a has been fairly popular technology, widely used in all kinds of display device. The latter is the gradual popularization of the new display technology in recent years, also known as the next generation display technology. In addition, there are QLED, MicroLED also known as the next generation display technology.

So what is the difference between OLED, QLED, and whether MicroLED, who is the next generation display technology.

Will burn the OLED screen

OLED is also called the organic light-emitting diodes (oleds), is refers to the organic semiconductor materials and light-emitting materials under the electric drive, through the carrier injection and compound leads to the phenomenon of luminescence. Principle we not much said, say, the LCD in the OLED comparing traditional what are the advantages.

First of all, is one of the biggest advantages of OLED, illuminated. Is different from the light of liquid crystal, need to depend on the backlight, can be spontaneous light OLED TV thickness can be done very thin, LG will even 2.57 mm of the thickness of the OLED TV did breathtaking, the thickest place no more than 5 mm. And because OLED for spontaneous light pixels, so can realize the switch of each pixel, realize the partition of backlit at pixel level, can theoretically infinite contrast.

Live in the laboratory of QLED

With OLED, let us say again QLED. QLED also called quantum dot light emitting diode, the advantages of OLED QLED, such as illumination, low response speed, wide color gamut, and so on. QLED, of course, has the advantage of OLED, which is QLED USES is inorganic quantum dot material, organic material than OLED live longer, there will be no burn-in phenomenon.

But as a result of quantum dot light emitting diode quantum dot because of its easy to affected by the heat and moisture shortcomings, unable to use the same process and OLED, need to develop new process. QLED technology has just started, the low reliability and efficiency, the unstable components life difficulties, solution process development restriction factor, so the QLED still exist only in the lab, there is a certain distance away from the commercial.

This is someone will ask, samsung has introduced a QLED TV, isn't it? QLED TV, in fact, now on the market, is not really a QLED, but can be seen as the upgrade version of LCD TV, through before the backlight of LCD TV and film, a layer of quantum dots make TV has a better image quality than traditional LCD TV and color performance.

So, now on the market QLED television is photoluminescence, need to rely on backlight; Is the real QLED electroluminescent, pixels can be illuminated.

Expensive MicroLED

MicroLED simply and actually in the way we see LED billboard, just MicroLED each small lights bead do the micron level. And OLED, Micro LED pixel level is illuminated, it will be the traditional inorganic LED array miniaturization, each size 10 microns in size LED pixels can be independent addressing, light.

MicroLED OLED technology, higher brightness than the existing, luminous efficiency is better, but a lower power consumption. But MicroLED has a big problem, is the manufacturing process is difficult, one of the most difficult is "huge amount transfer technology", in simple terms how to do an order of magnitude of the pixel point light is transferred to the substrate.

Production of high difficulty and low yield of MicroLED is expensive, the large size MicroLED television prices are not ordinary people can afford.

Who is the next generation display technology

So OLED, QLED, MicroLED who is the next generation display technology? If from the aspects of performance, the same is illuminated and also won't burn screen pixels, life expectancy longer QLED and MicroLED is no doubt those of OLED. But if consider various technique on the current development situation, is not the case. QLED is still in the stage of laboratory and production in sight; MicroLED rate is low, the high cost, and there is no real civil products; Compared to this, the OLED has been able to realize large-scale production, although the price is higher than the LCD on many generally, but also in the acceptable range.

Looked from the present stage, OLED if can further reduce the price again, perhaps is expected to replace the LCD as the next generation display technology. But in the long run, OLED is a transitional technology, QLED and MicroLED is the final shape. However, the current situation, although in the field of mobile phones and other small screen LCD has begun to be replaced by OLED, but in the field of television is still the absolute eldest brother.

For our consumers, actually will not go too much about which one to use display technology, cheap to use is king. Even if QLED and MicroLED can realize commercial, price XiaBuQu, also still can't shake the status of the LCD.
