- The domestic panel manufacturers with both LCD and OLED development
- Panel manufacturers in the Mainland has just completed the LCD layout, Japanese and Korean manufacturers has kindled OLED "smoke".
June 25, Panasonic and Sony announced plans to develop OLED TV production.
OLED is undoubtedly the hot words of the 2012 global panel industry. , OLED TV stole the show at the International Consumer Electronics Show in Las Vegas in early 2012.
As one of the greatest inventions of the 20th century - the TV since the advent of a profound impact on human life, the display technology to the third generation. As the first generation of CRT TV display technology, the occupation of the living room for up to half a century. The second generation LCD TV, large-scale into the public view, but only in 2056. LCD can just enter the homes of ordinary people, a new generation of OLED TV on stage.
OLED concept of early last year, there is heat, and industry competent authorities in China and Japan to this end a special industrial deployment. Compared to traditional LCD displays, OLED panel has a self-luminous, thin body, high contrast, rich color, high resolution, wide viewing angle and low power consumption and many other advantages. In addition, because OLED there is no liquid molecules, so the seismic performance of better and more durable. The same time, compared to TFT-LCD panel, with millisecond response, the response time of the OLED panel is a few thousandths of the former player does not occur when the trailing and dynamic picture jitter.
These characteristics make OLED panels become the ideal of the various types of display terminals, especially the TV display panel, as a new generation of display technology. However, due to very low yields of the major manufacturers in the production of large-size OLED panels, and such panel itself short life, which makes the manufacturing costs of OLED TV is very high, and has also become the reason for the large-size OLED panel can not be mass-produced. In contrast, the yield rate of the liquid crystal LCD panel can reach more than 90%.
However, the technology is in progress, the difficulty of breaking through. Transformed into the LCD panel production line OLED production line will be the main direction for the future development of the global OLED industry. Under the influence of the financial crisis, TV consumer market is faltering, if the existing equipment achieve technological upgrading would be a "wise choice".
In terms of technology, the OLED panel and LCD panel are similar. For example, use the TFT thin film transistor-driven structure - only OLED is a current drive, LCD voltage drive, crystalline materials will be the difference between the two used to achieve optimal efficiency. Therefore, Samsung, LG OLED panel plant in South Korea's construction is actually a transformation from the LCD panel plant.
The transformation from the LCD panel production line OLED panel production line with the obvious investment advantages, and can probably save three Daosi Cheng capital investment. OLED panel item LCD panel project, the greater amount of investment. Such as the construction of a 8.5-generation line LCD LCD panel needs about three billion U.S. dollars investment in OLED you need $ 7 billion in funds. With the release of OLED production capacity, LCD products in the market space will be further squeezed. If you do not "converting", but the new OLED panel production line, the panel faced by enterprises is the LCD project, "" twice as much losses.
TV and panel manufacturers have continued to OLED technology R & D and innovation. Sony and Panasonic will jointly developed the "printing technology" used in the essentials of the same printer inkjet ", because no large-scale production unit, so with the current mainstream deposition production technology compared to reduce production costs.
Sony and Panasonic established the printed OLED panel production technology, you can use the existing LCD panel is about half the cost of large-size OLED panel production, and printing technology, "Nikkei Shimbun pointed out that conducive to the formation of film-like substrate of plastics and other organic material film, so as to be expected to produce with a flexible OLED panels.
The recent initiatives in OLED continuously Japanese and Korean manufacturers, while South Korea's Samsung, LG and pushing the OLED on the other side of Japan's Sony and Panasonic jointly developed by OLED. Japanese and Korean TV and panel manufacturers has always been to lead the first global technology, several giant investment layout, feel OLED will replace LCD panel, which makes the domestic panel makers has just completed production line layout uneasy.
But there are also people in the industry believe that the alternative relationship in the early market, OLED panel and the LCD panel is not particularly evident. Because the price of OLED products will experience a high of more than two years. Studies have shown that consumers will switch to OLED TV OLED TV prices fell to 1.3-1.4 times of the LCD TV. At present, Samsung and LG OLED TV launched in the average selling price up to $ 8,000, almost more than ten times the price of an ordinary LCD TV.
OLED products prices fell in its yield issues to be resolved after the experience about three years time, just three years, is the domestic LCD panel makers to fight for the early return on investment valuable time.
Unfortunately, the LCD panel demand growth has tended to slow down, tablet PCs, notebook computers and smart phones in this area is still relatively strong growth, the demand for large - LCD TV market growth has been weak. However, the LCD panel capacity, but at this time the rapid growth, even in the case of many production lines has not been fully put into operation, the LCD panel production has been relatively surplus. This is not only the survival status of the domestic panel makers, is a big loss of the global industrial chain.
Overcapacity is followed by mergers, survive to become a top priority by the panel factory.
Survival is not so easy. In addition to the slowing market demand, the domestic panel manufacturers of the LCD panel production experience and core technology still lags behind the chemical materials and equipment in Japan and South Korea, the LCD panel is also dependent on imports. According to the United Nations trade in goods statistics show that the liquid crystal such display is one of the four Chinese imports of goods, every year the LCD screen of the import bill had more than one hundred billion yuan, not to mention the core of next-generation OLED panel technology.
Global panel industry has been in the pattern of the three pillars of Japan, Korea and China Taiwan, mainland manufacturers are always looking dust follow. LCD TV's inception, China's color TV industry is highly troubled, materials and equipment are heavily dependent on imports of the lack of core small screen. In recent years, in support of national policy, China's flat panel industry has experienced a process from scratch, nearly two years of development is significantly accelerated. With the commissioning of the BOE, Huaxing power, as well as LGD Guangzhou, Samsung Suzhou project to restart, the mainland generation LCD panel production line have been put in place, but at this time Japan and South Korea began a new play. Japan and South Korea OLED panel production line have mass production, these hundreds of billions of domestic investment is not a boondoggle? So far, the leading enterprises of the domestic panel BOE facing huge investments in the panel, recycling is still very distant.
Struggling, but domestic panel makers have no choice. LCD panel production experience and technical reserves are not enough, the most sensible approach is immersed in the existing production line to absorb the existing technology, the accumulation of production experience and technical reserves. On this basis, technology and product innovation, and to lay the foundation for industrial upgrading.
History is always surprisingly similar. Ten years ago the country had just completed the layout of the CRT industry chain, flat panel display to the era of the "sudden" arrives. The country is now in LCD field just to pick up with the Japanese and Korean manufacturers OLED production line publication of the plan and the introduction of OLED TV business, the domestic LCD panel companies seems to butter, then the CRT enterprises fall into a passive, not enough time to catch your breath on again struggling to get up to catch up.
The panel of Chinese domestic enterprises in the world's largest panel enterprises agreed OLED technology developed in the last year has just completed the 4.5-generation LCD panel line, five-generation line, the six-generation line and the 8.5-generation line layout. As a result, the pace of development of new technologies on the domestic panel inevitably one step too late. OLED panel, South Korea's Samsung and LG, respectively, a monopoly market share of the small screen and big screen.
Of course, the domestic panel companies is not new technology unconscious. June 2, 2011 China's OLED Industry Alliance brings together the enterprise engaged in the production of small OLED Kunshan CIGNA, Sichuan Changhong, Foshan and rainbow. However, due to the imperfect panel industry chain, the upper glass substrate, and chemical materials and so controlled by others, so its production plan is still lagging far behind the Japanese and Korean counterparts, and even China Taiwan's AU Optronics and Chi Mei panel enterprises.
Original development capabilities, only behind the Japanese and Korean manufacturers picked up the pace. Even the most advanced generation OLED5.5 production line put into operation in the Ordos, but not sound industrial chain, including materials, masks, glass packaging, including, in addition to bypass the technical barriers set by the Japanese and Korean manufacturers, domestic OLED industry development of a long way to go.
