However, for China's home appliance industry, which has been following Japan and South Korea in product development, innovation and breakthrough are not easy. The "screen" defect also makes Chinese home appliance companies in crisis on the road of high-cost investment in OLED layout.
Korea and Japan contend OLED
OLED TV has long been optimistic about the power giants because of its own advantages. In the field of OLED TVs, Sony, one of the earliest manufacturers involved in the OLED industry, once introduced a number of small-size OLED display devices. In 2007, it launched the world's first 11-inch OLED TV. The price was too expensive, resulting in slow sales. To achieve the desired results, Sony has not found a solution to reduce costs. Sony announced at the end of March this year that it stopped production and sales of OLED TVs in the Japanese market.
Compared with Sony's low-key exit, Samsung's high-profile debut is more eye-catching. Recently, Samsung made it clear that it will invest 1.3 billion US dollars to build the 5.5th generation OLED panel factory, and said that the panel factory will be put into operation in January 2011, which will launch an impact on OLED TV. Samsung's SMD company has the world's largest OLED panel production line. Samsung has been promoting the popularization of OLED screens on smart phones and portable multimedia devices. Currently, OLED panel products have been monopolized by Samsung, and its market share has reached 98%.
OLED TV "short"
OLED TVs, which are highly anticipated by various parties under the aura of energy saving, rich color, no smearing, no visual angle limitation, have been plagued by development due to large investment and low output. It is understood that the OLED luminescent material has very poor anti-oxidation ability after being energized, and it needs vacuum glass to seal, which regains the old path of TFT-LCD. Since the OLED is a current type device, a relatively high current drive is required, so an LTPS TFT substrate is required. LTPS is destined to cost the OLED high. It is reported that the current production rate of large-size OLED panels is less than 30%, resulting in high manufacturing costs, while LCD panels can reach more than 99%. The pixel distribution of the OLED is not high, so the OLED is suitable for a slightly larger size, but the size is too large, and the cost advantage is even worse.
When Japanese companies opt out and Korean companies make high-profile appearances, Chinese TV companies are eager to pursue OLED TVs. There is a voice to describe this: in the CRT era and the LCD era, mainland companies are catching up with Japan and South Korea, and in the OLED era, which is seen as the upcoming TV industry, mainland companies expect to be at the same starting line as Japanese and Korean companies. .
Chinese enterprises "listing"
At present, OLED is in its infancy, and cutting-in is considered to be the best time for Chinese home appliance companies to catch up with Japan and South Korea.
In April 2008, Changhong, which has been erratic in technology in recent years, began to build China's first OLED display production line. On July 15 this year, Rainbow's 4.5th generation AM-OLED production line project was signed and settled in Shunde. In addition, Tianma Microelectronics recently announced that its AM-OLED line will be trial-produced in the third or fourth quarter of 2010. By 2011, it will reach a production capacity of 250,000 pieces per month, as well as AVI of AMINO. OLED has also been built.
In this regard, there is a voice that in the field of OLED, the domestic appliance industry is currently at the same level as Japan and South Korea. However, the author believes that the technical gap between domestic brands and Samsung and other companies can not be underestimated. While entering OLED, the breakthrough of upstream equipment and its key technologies can not be ignored.
The upstream link of the OLED industry chain is weak, and the supporting capacity of the industry is lacking. In fact, not only the OLED TV research and development stage, but at every stage of the development of the TV industry, the domestic TV panel production line has been in a state of lack, which has also greatly increased the external dependence of the domestic industry. The survival of the industry is greater than the development of the status quo, the flat revolution revolution is brought about the hollowing out of the color TV industry and the crisis of marginalization - increase efficiency, no increase in income, low-end profits of high-end products, vicious competition is still deepening.
