AM-OLED development planning BOE announced positive new display layout
Recently, in the "Display Week 2011 in Shenzhen, Shenzhen Optoelectronics (International) TV Festival" (referred to as optical display weeks), the flat panel display as a domestic leader in the field, carrying a variety of independent research and development BOE TFT-LCD and AM-LCD OLED product appearance, and announced a new future in the AM-OLED display industry development plan, subject to the industry's attention.
As the ownership of BOE touch lcd module core technology leader in the display area, relying on independent innovation and technology, not only in mainland China to fill the gaps in the LCD industry, and the use of their own area in the TFT technology accumulation and industrial advantages, integration resources and to create other new AM-OLED display technology innovation platform. It is understood that has been built in Beijing BOE Technology Center, China's first TFT-LCD process on the National Engineering Laboratory located in the BOE Technology Center; built in Hefei, "Anhui Province Engineering Research Center for Flat Panel Display", and with the Hefei University of joint, the high-tech talent development, and own proprietary technology; in Chengdu, the BOE also cooperation with the University of Electronic Science and Technology OLED build a joint laboratory.
At present, relying on behalf of Chengdu, 4.5 lcd module tft production line, AM-OLED BOE has begun to transform the production line, while actively promoting high-generation line of AM-OLED layout. Expected during the year, the BOE can launch mobile phone and other mobile terminals for use LTPS (low temperature polysilicon) display panel; in the next 3 to 5 years, will continue to introduce IT and TV and other information, video terminals with AM-OLED display panel .
BOE Display Technology R & D future, said Wang Gang, Director, BOE display lcd module will be in mastering the core technology on the basis of independent, actively promote the advancement of domestic and other new AM-OLED display technology R & D capabilities and industrial construction.
Currently, AM-OLED technology in the large size of the application is still in the initial stage, the relevant government departments to support and core business efforts, in order to point driven industry and industry chain development, China's AM-OLED industry will be possible to achieve curve beyond.
Among the many new products in the flat panel display, OLED new display (organic light-emitting diode) because of its self-luminous, fast response, ultra-thin, flexible, etc. has attracted industry attention. OLED display in different ways based on driver, divided into passive drive OLED (PM-OLED) and active matrix OLED (AM-OLED) categories.
Compared with the PM-OLED, AM-OLED has a faster response, higher contrast, wider viewing angle characteristics, have more applications. Recent market research also shows, AM-OLED display market growing rapidly, but the PM-OLED market is shrinking.
TFT-LCD with the principle of approximation, AM-OLED displays is the use of TFT of each pixel corresponding to the circuit to control the unit as a light-emitting OLED pixels; difference is, AM-OLED is by controlling the current flowing through the OLED light-emitting unit, and therefore pixel on the drive back has different requirements. Therefore, AM-OLED technology and manufacturing processes is still in development, AM-OLED backplane technology development driven AM-OLED technology is currently the most important direction of research and development, while the large size of the problem and to reduce costs is constrained AM -OLED important factor in industrial development.
On the whole, TFT-LCD and AM-OLED industry has a great commonality, and to undertake sexual. AM-OLED Backplane key drivers still need to drive TFT, the manufacturing process with the existing array of TFT-LCD module process technology and equipment and technology in most aspects can be shared by the existing TFT-LCD production line a small amount of equipment to add the transformation and AM-OLED will be able to meet future product development and production.
