Over the years, OLED and quantum dots have dominated the hot technologies in the display industry.

From OLED TV to quantum dot TV, to mobile phones, displays and other small and medium-sized OLED and quantum dot screen applications.

In the view of many people in the industry, OLED is the general trend. However, the sudden appearance of microled display technology in the industry has brought more imagination to the display industry.

Many people who know about microled display technology even say that microled display technology can kill OLED and LCD.

In the LED display industry, microled as a new generation of display technology, many domestic and foreign manufacturers are actively investing in research and development.

More and more panel manufacturers have introduced microled solutions with glass backbones, and microled ultra high definition display products have been launched.

Micro led and mini LED which is the trend?

All parties promote the development of microled

It was in 2012 that consumers first saw screen products using micro LED technology.

At that time, Sony exhibited a 55 inch Full HD resolution “Crystal LED display” product. This technology is much better than its competitors in terms of contrast and gamut.

The emergence of mini / microled display technology is regarded as a new blue ocean market by enterprises, and its growth trend is more and more obvious.

At present, the national level vigorously promotes the development of ultra high definition video industry. 8K + 5g technology provides a new opportunity for the development of new display technologies such as small spacing Mini / microled.

For example, in December 2019, “Huangpu District, Guangzhou City? Guangzhou Development Zone to promote the development of new display industry support measures issued and implemented, the measures are mainly for the production and development of enterprises with large incentives, in order to promote the production and development of high generation OLED, AMOLED, mini / microled and other new display industries.

In terms of R & D and implementation of microled technology, enterprises and panel manufacturers including Sony, Samsung, TCL, BOE, Konka, zhaochi, Yade, Huacan optoelectronics, alto electronics and Lehman optoelectronics are making efforts.

From the panel line, microled display chip, microled TV, microled mobile phone, large screen advertising, digital signs to microled security equipment, the microled display industry has developed in an all-round way.

CES? 2021? The first? Look online.

Among them, the microled products on display include 110 ”, 99 ”, 88 ”, and other sizes. The new products adopt micron level LED light source self luminous design. Samsung’s high-end neoq LED TV also adopts ultra-thin Mini LED light source with new array forming structure.

Sony released a new generation of “black color crystal” microled splicing display at ces2021.

However, Sony did not call these products “home color TV sets”. Sony said that consumer TV technology will also be applied to microled displays, including X1 video processor and motionflow technology to achieve smoother images.

Microled display can achieve up to 1800 nits brightness, wide color gamut, HDR and 120fpshfr and many other functions.

At present, new displays such as mini / microled have become the focus of many manufacturers, and mini / microled is regarded as the key to seize the new technology highland by industry people.

Among them, panel companies actively follow up, such as Yade, abison, alto electronics, and Lehman optoelectronics, while Lehman optoelectronics has achieved mass production of microled ultra high definition display products based on cob advanced integrated packaging technology.

Relevant industry analysts said that microled currently focuses on high-end display field, mainly in two directions of ultra large size and micro size development.

At present, many large-size microled products have been put into the market and become the development trend of new display industrialization. Companies like Samsung, Sony, LG, Huaxing optoelectronics and Lehman optoelectronics have taken the lead.

However, if the mini / microled industry wants to develop better, it still needs the cooperation of the upper, middle and lower reaches of the industry chain. It can’t do without any link.

Can microled become the new engine of LED display industry

From the previous high dependence on imported resources to the current independent research and development of chips, packaging, materials and equipment and even the application link in China, China’s LED industry has gained a large market in the global LED market after 10 years of development.

In the research and development of new markets such as mini / microled, domestic related enterprises are also in the forefront.

Relevant data show that relevant enterprises in China have achieved remarkable results in the field of mini / microled, including chips, packaging, equipment materials and downstream display applications. Enterprises have invested a lot of talents and financial resources in R & D and production.

Including some international giants, in the field of mini / microled, they are also seeking OEM production from domestic enterprises.

Sanan optoelectronics has invested 12 billion yuan to set up the III – V compound semiconductor project in Gedian Economic and Technological Development Zone, Hubei Province, mainly engaged in the R & D, production and sales of mini / microled epitaxial and chip products and related applications.

Huacan optoelectronics has been in the field of mini / microled for a long time, and has made substantial progress; Konka Group has invested 30 billion yuan in the construction of Chongqing Konka Semiconductor Optoelectronic Industrial Park, focusing on microled project research.

On October 31, 2019, we officially released the aphaea future screen series products and launched the microled TV smartwall; TCL announced the microled TV sample in September 2019, with a 132 inch screen size.

In the field of mini / microled, in addition to Samsung, apple is also actively investing in R & D.

As early as 2014, apple acquired luxvue, thus having the most complete layout of micro led patent technology in the industry. 1500 in the world? Among microled patents, apple holds 62 key patents, ranking first in the world.

At present, due to the technology gap, China’s panel enterprises are still in the catch-up stage in OLED; In the mini / microled industry, due to the joint efforts of many enterprises, it has developed to the stage of competition.

Relevant industry analysts said that domestic enterprises have the opportunity to surpass imported brands in mini / microled technology, and it is also likely to become a new machine in LED display industry.

But we also need to face up to the gap, catch up, and deeply tap this technology to achieve the overall upgrading of the industry.

Giant’s new favorite? Can microled surpass OLED?

Microled display has the advantages of high color saturation similar to OLED, self luminous principle and less than 1 / 10 power consumption of LCD panel.

In addition, apple, Samsung, Sony, Huaxing optoelectronics, Huacan optoelectronics and other industry leading brands have launched related products, which makes microled display technology gradually become one of the most popular technology topics in the industry.

High production difficulty and low yield lead to high price of microled. At present, the price of large-size microled TV is not affordable by ordinary people.

With the development of OLED panel technology, the price of OLED TV is getting lower and closer to the consumption level of consumers.

The speed of commercialization of OLED is much higher than that of micro led. Since OLED TV officially entered the market in 2013, after six years of commercialization, the market scale has reached US $2.5 billion in 2019.

China Institute of electronic information industry development once predicted that the market scale of silicon-based OLED is expected to reach 90 billion US dollars in 2023. Among them, AR / VR market space will account for 68%.

From the performance point of view, the same pixels are self luminous and will not burn screen, longer life microled is more stable than OLED.

But from the development of various technologies, microled has low yield and high cost.

At present, although there are many enterprises researching and developing technology, the scale of civilian products is small; With the unremitting efforts of lgdisplay, large size 4K? The yield of OLED has reached 90%, which seems to be a trend to replace LCD.

In terms of the voice of OLED technology, Korean brands are temporarily in the lead, while Chinese and Japanese enterprises are still catching up.

However, whether it’s mass production of various OLED products or cooler future, the Chinese market will take the lead.

For consumers, in fact, they don’t worry too much about which display technology to use. It’s true that affordable products are easy to use.

Today, OLED and microled are both in commercial use. If the price does not go down, the status of LCD may not be shaken in the future.

At present, the global OLED TV market is developing well, and the demand is surging. With the improvement of yield of OLED production line, the demand of high-end market for OLED can be guaranteed under the existing capacity.

At present, OLED has become the mainstream trend of display technology. In terms of technology, price and manufacturing cost, microled is hot, but it does not have the same strength as OLED.

In the view of industry insiders, in the future display technology “contest”, it is also facing variables.

Domestic panel enterprises and color TV brands need to be prepared for the iteration of display technology and grasp the final value of LCD.

At the same time, the layout of OLED, the development of microled. When LCD is declining, both OLED and microled have solutions, which will not affect the development of enterprises.

With the gradual maturity of these two technologies, it will also provide more possibilities for the performance growth of color TV and other display enterprises.
