In the field of TV, whether it is the earlier PDP (plasma) and LCD (liquid crystal), or the current laser, QLED (quantum dot), OLED (organic electric laser Display), Mini/Micro LED, the battle for a new generation of display technology has always been It has not stopped, and when the technical direction of the competition is still uncertain, most brands choose to “walk on multiple legs”, in order not to be abandoned by the market in the new competition.
With excellent performance and flexible applications, Micro LED displays have ushered in broad development prospects, and giant companies have begun to deploy.
A few days ago, Konka Group launched the world’s first Micro LED smart watch, APHAEA Watch. This product adopts Konka’s self-developed P0.12 AM-LTPS Micro LED micro-crystal screen. The LED chip is only 30 microns, and the dot pitch is reduced to 0.12 mm. It is the Micro LED display with the smallest LED chip pitch in the world.
Chang Dong, Co-Vice President of Konka Group and President of Shenzhen Konka Electronic Technology Co., Ltd., said that Konka has already established a layout in the Mini/Micro LED field. “Considering the large-screen development of color TVs, Konka will continue to improve its layout in the Mini/Micro LED field.” Chang Dong said that Konka electronic Technology Co., Ltd. is working closely with the Konka Group semiconductor Division to actively promote the launch of self-developed Mini LED and Micro LED products.
In fact, since the beginning of this year, the Micro LED field has become a hot spot for market investment. Whether it is consumer electronics leaders such as Samsung and LG, or TV manufacturers such as Konka and TCL, as well as panel companies such as BOE and Huacan Optoelectronics, the upstream, middle and downstream of the industry chain are all in the process of More attention, capital, and technology are put into the hot Mini/Micro LED market. According to incomplete statistics, from January to April this year alone, nearly 15 billion yuan was invested in Mini/Micro LED projects.
Display technology has gone through several iterations since the birth of television. In the field of LCD TVs, the most popular display technology at present is OLED. One of its biggest advantages is self-illumination, which can make the TV very thin, have a wider viewing angle and lower power consumption. In addition, OLED can also be produced on different flexible substrate materials such as plastics and resins. The current popular curved screen mobile phones and foldable mobile phones take advantage of this feature of OLED.
However, OLED also has fatal flaws. The organic materials used in it age faster than the inorganic materials used in LCD, and OLED will leave afterimages when displaying a static image for a long time, that is, the unique burn-in phenomenon of OLED. . Not only that, currently only LGD can produce large-size OLED panels, and bottlenecks such as insufficient production capacity and high prices restrict the popularization of OLED TVs.
Quantum dot (QLED) technology is a more popular liquid crystal display technology in the industry. Due to the use of different backlight sources, there are many differences in performance. QLED TVs have more advantages than traditional LED LCD TVs in terms of picture quality and cost. . However, there are also many disadvantages of quantum dots. For example, in order to ensure the improvement of TV brightness, the use of a large number of light-emitting quantum dots leads to high power consumption and short service life. More importantly, quantum dots are mainly composed of atoms such as zinc, cadmium, selenium and sulfur, and cadmium is a volatile carcinogen. Once the TV is used for a long time, it will bring hidden dangers to the health of users.
As for the laser display technology, in addition to its advantages of infinite expansion, low cost, and easy installation, healthy eye protection is its most commendable advantage. From the imaging principle, the laser display adopts the reflection imaging method, the light received by the human eye is very soft, and there is no edge effect between the pixels, which can achieve full pixel luminescence, effectively reducing the light intensity per unit area, and it is not easy to cause people to watch for a long time. Eye fatigue. However, the principle of laser display is very similar to that of projectors, requiring an external projection device to be placed in front of the panel.
The industry pointed out that the current development of display technology is more complicated than the original PDP and LCD competition. There are open and secret battles between various display technologies, and powerful manufacturers are actively deploying to try to dominate the next display era.
face the competition
As TV products gradually move towards high-end, display technology begins to blossom everywhere, but why does Konka bet on Micro LED technology?
Industry analysts believe that, on the one hand, this is a trillion-level market with broad prospects. Some institutions predict that 2020 is the first year of the explosive growth of Micro LED, and the global market size will reach 1.41 billion yuan; it is estimated that by 2022, the market size of Micro LED is expected to reach 8 billion yuan. In the eyes of Zhou Bin, President of Konka Group, the market prospect of Micro LED is far more than that. Zhou Bin said that the semiconductor industry is a strategic emerging industry vigorously developed by the country. As a new generation of semiconductor display technology, Micro LED has attracted much attention due to its advantages of high brightness, high contrast, and low power consumption, especially in ultra-large screens and wearables. The field has huge market potential and may become the next trillion-dollar new market.
On the other hand, the rise of the semiconductor industry is the best breakthrough to break the monopoly of foreign display technology. As we all know, from LCD, OLED to QLED, various display technologies continue to develop, alternate or replace, but key technologies and market dominance are always in the hands of foreign brands. There are many reasons behind this. The key to the problem is that Chinese companies start relatively behind. This is not the case with Micro LED display technology. Now it is in the initial stage of cultivation, and the domestic and international development levels are almost on the same level.
In the eyes of industry insiders, although Mini/Micro LED is the outlet, it is still difficult to completely replace OLED as the mainstream of the industry in a short period of time. From the application point of view, Mini/Micro LED can be divided into two directions: backlight and self-illumination. However, due to the huge transfer problem of self-illumination technology, mass production is its main bottleneck. Affected by this, backlight technology has become the mainstream technology direction of Mini/Micro LED, but the display effect has been compromised.
OLED, which has already been mass-produced, is gradually opening the door to the high-end market. Its characteristics of being thinner and lighter, high brightness, low power consumption, fast response, high definition and good flexibility have also been deeply rooted in the hearts of the people. Display Technology”.
However, with the gradual efforts of Konka and other manufacturers on this track, the commercialization of Mini/Micro LED is also accelerating unprecedentedly. The market generally believes that, next, Mini/Micro LED will face the competition with OLED, and Mini/Micro LED will replace OLED in TV, computer, smart watch and smartphone industries one after another, and this process may continue for a long time a period of time.
