OLED has broad prospects, low product yield and low impact on the road to popularization

However, another news inside the industry shows that the yield of OLED is only 1%, not more than 2%, which makes many manufacturers have a bit of awkward attitude towards OLED, pay close attention, but hesitate. The real arrival of the "OLED era" may not be as smooth as expected...

Broad prospects, the industry is generally optimistic

Not long ago, the State Key Laboratory of Luminescent Materials and Devices of South China University of Technology and Guangzhou Xinshijie Optoelectronics jointly launched a domestic color flexible AMOLED display, and at the just-concluded fifth Asia (Guangzhou) flat panel display industry exhibition, the display panel Manufacturer LG Display has demonstrated a TV with OLED panel thickness of only 4.3 mm. LG Electronics also revealed that it will officially launch OLED TVs in the end of September and October, while in the US market, Samsung recently The 55-inch OLED TV is announced to be available in the US.

As early as around 2008, OLED display products have been unveiled at the prestigious CES International Consumer Show in the United States. OLED products are even considered to be flagship products that represent future trends.

In this regard, the insiders of Beijing Jichuang, which is related to the panel and optoelectronics industry, analyzed to reporters: "In fact, this is the game between the Japanese and Korean two panel camps. Because the earliest flat panel displays, including plasma PDP, LCD LCD and Later, the LED camps that were further upgraded by LCD panels were all started in Japan. Later, the Korean system integrated the advantages of LCD panels to further create OLED panels. The panel competition is also a core competitiveness that will dominate the future product line and industry chain."

Looking up in the market, today's Japanese brands represented by "3S camp" (Panasonic, Sharp, Sony), whether in the panel market or the finished color TV market, are not as good as the Korean camp represented by Samsung and LG. Therefore, the rise of OLED products represented by Samsung and LG in the market is also the embodiment of this pattern.

The OLED display panel is also in line with the trend of ultra-thin, high-definition display technology in today's display technology, and it can be used in mobile phones, televisions, computers and other finished products. The mass production of OLED panels and the emergence of OLED TVs have become a major event in the industry.

From the perspective of the global market, since last year, the TV market has generally been unsatisfactory, demand has declined, and sales performance has been weak. From the previous 3D to today's 4K, to OLED TV, TV manufacturers hope to promote the TV market through the display and function improvements.

The yield is too low, which may affect the road to popularization.

OLED panels are available, but for the future of the OLED industry, there are still many unclear factors within the industry. One of the main reasons is that the maturity of OLED is not high. Liu Weizhi, director and vice president of Skyworth Group Co., Ltd. and president of Skyworth RGB Electronics Co., Ltd., said: "The current yield of OLED is very low, only about 1%." Such a low yield rate means that the cost of the manufacturer is too high. Will lead to high product prices.

Another major reason is that the supporting industry chain is not yet mature. In view of the soft screen characteristics of OLEDs, supporting industries such as imaging circuits and information transmission supporting OLED mobile phones and televisions need to have higher requirements. Currently, OLED chips are used. The accessories are still far from mature.

Although OLEDs are widely concerned, the prospects remain unknown. Hong Maosheng, the main person in charge of the LCD panel supplier and Innolux (Taiwan Chimei Electronics) TV panel business, said: "OLED is not bad, but it costs a lot of money and costs a lot." He believes that OLED and 4K TV will have A coexisting relationship, whether OLED is favored by consumers in the market, is being observed.

The attitude of relevant manufacturers also shows the current status of the current OLED industry. Up to now, it has been clear that OLED TVs have only been launched in the Chinese mainland market. Sony has demonstrated OLED TVs at many large-scale exhibitions and has not widely promoted OLED TVs.

Wearable products are expected to "early taste"

For the finished products of OLED, only the products such as TV sets are officially released. The biggest feature of OLED is that it is light and thin, can be bent and folded, but it is obvious that such a feature is applied to the large-screen display. Only the surround screen can achieve the effect of a ring-screen movie. Other features are at least difficult to show on the TV at present. . LG said to reporters: "OLED TVs are just curved, made into a curved surface, but they can't be folded."

It's hard to imagine what a OLED electronics product can be folded. As for the OLED mobile phone, it seems that the screen can be folded and it is difficult to become its main selling point. The reporter's response to a number of mobile phone manufacturers after consultation was generally "closely concerned" or "research and development".

The only exception is that many small screen products, using OLED displays, can have unexpected effects. For example, the display screen using OLED can be made into a curtain, which can be used as a TV screen when it is rolled up during the day, and can be used as a TV screen at night; for example, various wearable display products, smart watches, bracelets, etc. can be used for OLED; The small and sleek OLED display can be used as a "human body display" if it is mounted on a cuff, collar, shoes, tie, etc., and can even be used as part of a hidden display. In the future, any item around us can become a display.
