LCD panel: large size smooth small size

Recently, China's BOE and China Star Opto-electronics Line 8.5 have announced mass production one after another. In stark contrast to the domestic Shangmao Generation Line, LGD recently postponed the start date of the 8.5th Generation Line in Guangzhou recently due to the slump in the global LCD panel industry. As the profits of large-size LCD panels gradually decline, the small-size panel market is becoming increasingly popular, and is favored by manufacturers. The liquid crystal panel industry is at a crossroads, and the wrestling of the upstream panel is stuck.

Big size busy upgrade

Overcapacity is cyclical, and there is still room for growth in the demand for large-size LCD panels in the long run.

At present, the global LCD panel sales are becoming increasingly saturated. Overcapacity has become an indisputable fact. Different from LGD's postponement of the 8.5-generation line construction, the 8.5-generation line built by China’s BOE and Huaxing Optoelectronics has brought mass production news. In the winter season of the LCD panel, a warm welcome came.

The reporter learned that BOE Beijing has a total investment of RMB 28.03 billion for the 8.5-generation line and a glass substrate design capacity of 90,000 tablets per month. It is expected that the annual output will reach 13 million LCD screens after production, and the current comprehensive product yield has reached 85%. The total investment of China Star Optoelectronics 8.5 generation line is 24.5 billion yuan, and it will also realize the localization of mainstream LCD TV panels from 26 inches to 55 inches.

Zhang Yu, vice president of BOE, said in an interview with a reporter from China Electronics News: “According to DisplaySearch, the demand for LCD TVs in the domestic market will be 50 million units in 2012 and 80 million units in 2015. One 8.5 generation line, according to the With different product sizes, the production capacity of 90,000 glass substrates can produce between 12 million and 14 million LCD screens per year.Based on this calculation, if you only meet the demand for LCD panels in China, you need 6 8.5 generation lines. The overcapacity is caused by the global economic downturn. We believe that in the near future, there will be blowout requirements for large-size LCD panels."

It can be said that for the mature industry of liquid crystal panels, BOE and China Star Opto-Electronics 8.5 generation line have been put into operation one after another. The more important significance is that China's color TV LCD panels have achieved nothing, and completely ended the large-size LCD display completely. Depends on the history of imports.

Coincidentally, on the occasion of the start-up and mass production of two senior generations in China, panel giant Samsung Electronics recently reported that the 7.5-generation panel production line invested in China may be upgraded to the 8.5-generation line. In response, the related person in charge of Samsung denied to the “China Electronics News” reporter that Samsung Electronics had only submitted an application to the South Korean side. As for upgrading the LCD panel in China to the 8.5-generation line, although there is an interest, it has not been Clear plan.

Zhang Bing, director of market research at DisplaySearch, said in an interview with a reporter from China Electronics News: “From the product point of view, even if Samsung upgrades the 7.5-generation line, it only shows that the mainstream size of the panel cutting has changed, but the planning in China No substantive changes have taken place.Our country's BOE and Huaxing Optoelectronics have only 10% of the global market share and are second and third line manufacturers. To compete with foreign companies for market share, we must increase production and yield, and improve the supply chain. Only in this way can we have more room for development in the future."

Small size gorgeous turn

The size of the LCD panel is not as large as possible, and the characteristics of high-precision and high-profitability of the small-size LCD panel are favored by manufacturers.

Different from the increasing saturation of large-size LCD panels, the small and medium-sized LCD panels are in short supply due to the hot demand of tablet computers and smart phones. In this context, Sony, Toshiba, and Hitachi are the three largest Japanese electronics companies, and are dedicated to the research and development of small and medium size LCD panels.

This can not help but conjecture, in the LCD panel market, whether there is a large size to the small size of the shift trend?

Sun Zhengmin, secretary-general of the Shenzhen Flat Panel Display Industry Association, told the China Electronics News: “Compared to high-generation LCD panels, Japanese companies are more competitive in small and medium-sized areas. Sony and Toshiba have always had an advantage in small and medium size. Hitachi’s production line The highest level before this is only the 6th generation line. Considering the small and medium size market is better, several companies are also bound to cooperate."

He believes that enterprises should be positioned according to their own products, should not blindly obey, due to high precision, high value-added characteristics of small and medium size LCD panels, in the production is difficult, such as low temperature polysilicon technology LTPS, only a few companies now Core Technology.

However, according to Ouyang Zhongcan, an academician of the Chinese Academy of Sciences, the flat panel display is saturated in large size, and laptops are likely to be replaced by tablets. According to the inflection point analyzed by the Taiwan Institute of Industrial Technology of Taiwan, there are large sizes to medium and small sizes. The shifting trend.

In fact, during the development of the LCD panel industry, people used to focus on the pursuit of newer technologies and the production and application of larger-size panels. However, we must realize that LCD panels are not necessarily the bigger the better, and the production line should be Layout based on product type. Among the many terminal display products, it is undeniable that TV's output value contributes the most, but with the rise of smart terminals, the market's demand for display panels also changes.

Game with OLED

The LCD panel still dominates the mainstream. In the future, whether new technologies such as OLED can highlight the advantages will determine the outcome of the game.

With the rapid development of cloud computing and mobile Internet of Things, human-computer interaction is more reflected in the process of human-screen interaction. With the advent of new technologies, the demand for LCD screens from consumer electronics manufacturers has further increased.

According to Zhang Bing, television, tablet computers and smart phones will be the three areas with the greatest potential. In the TV market, in the future, based on the development of TFT and 3D, AMOLED will quickly expand from small size to large size; for panel used in the tablet, high resolution, ultra-light and ultra-thin are more favored; and for mobile applications, the small size Panels should pay more attention to the development of technologies such as AMOLED, low-temperature polysilicon, and IPS.

Zhang Yu told reporters that the BOE product line covers the 1.8-inch to 55-inch panel area. In addition, BOE has always paid close attention to new trends in industrial technology and has conducted a large number of technology research and development and reserves in forward-looking display technologies such as AMOLED. Relying on the Chengdu 4.5-generation line, BOE has started the transformation of the AMOLED production line and actively promoted the layout of the AMOLED high-generation line, and invested in the construction of the first domestic 5.5th generation AMOLED organic light-emitting display device production line in the equipment manufacturing base in Ordos, Inner Mongolia.

Today, the scale of LCD TVs has reached 100 billion yuan. Such a large scale will inevitably make LCD panels occupy the mainstream for a period of time. However, as the TV market becomes increasingly saturated and new technology innovations continue to increase, the advantages of new technologies represented by OLEDs are becoming increasingly prominent. In the next few years, it will be necessary to see whether OLEDs can gain advantages in this game.
