The future of display technology: Chinese most of the layout?

In the production line layout of the high generation LCD panel, our country has been passively followed to the initiative, and the investment of the 10.5 generation line has created a new pattern of competition in the global LCD panel industry. But now display technology, in addition to the mainstream TFT-LCD, there are OLED, QLED, print display, Micro, LED, laser display and other technologies.

Professor Guan Xudong, Department of microelectronics Peking University School of information science and technology pointed out that liquid crystal display technology to guard against other shocks, but also to strengthen the forward-looking technology research and development, pay attention to the non - liquid crystal display technology. So, which one is the most worthy of China's layout of the future display technology?

OLED technology has been supported by the state

By the upstream high generation LCD panel production line put into production, in recent years, large screen TV market has become the development trend of domestic 55 inch color TV has become the mainstream size, but also to 65 inches above the forward market. According to forecasts, in 2018, more than 65 inches of LCD TV may account for about 8.7% of the entire TV market, and by 2020, 70 inches more than LCD TV will account for 10%.

Facing the large-scale air outlet of TV products, the global panel enterprises are scrambling to layout the production line of super generation LCD panel (10 generation or more). Two more than 10 generation panel production line construction in the BOE and Huaxing Power Investment, Foxconn, LGD, HKC, CEC and other companies have begun the layout of high generation LCD panel production line. According to statistics, there will be 8 or more than 10 generations of LCD panel production line on the agenda.

Compared with the LCD panel production line, although the domestic high generation OLED production line is still vacant, the domestic panel manufacturers have already begun to develop printing OLED technology. Zhu Changchang, a senior consultant at TCL Research Institute, explained that it is good to make small size OLED with the evaporation process, but to make a larger size, OLED has a lower rate of good quality and the price is too high. Samsung has given up. Printing OLED can reduce costs. So, as early as in 2012, TCL group vice president and Dean of Research Institute Yan Xiaolin first put forward in the country, printing display is to break through the large-size OLED display technology bottleneck is an important direction.

In 2014, the Guangdong provincial science and Technology Department of Guangdong Province approved the establishment of a printing industry as the core, supplemented by the giant top intelligence resources display technology innovation alliance, then set up the printing display OLED open platform technology and public R & D, Guangdong Ju Hua printing display technology limited company was established.

And our country in the "13th Five-Year" national key development program has been the development of OLED printing technology as the key support of the project, the national major projects in the drafting of new materials has also been included in the OLED printing technology.

In 2016, Guangdong Ju Hua printing display technology Co Ltd (owned by TCL Huaxing Power Company, Tianma microelectronics Limited by Share Ltd jointly funded) and DuPont, Japan and the United States Sumitomo chemistry, Nissan Chemical Ke Di enterprises signed a strategic cooperation agreement, which will support China in the OLED technology in the development of printing materials and technology needs for China tailored equipment related research.

Zhu Changchang pointed out that Huaxing photoelectric, Guangzhou new vision photoelectric and Fuzhou University joint research key printing OLED, has made 31 inches FHD printing OLED samples. Now China in Guangzhou Science City plant has been built, is entering the equipment commissioning phase, probably at the end of August the test line can be opened.

China's laser display technology is comparable with foreign countries

Whether it is printing, OLED technology research and development, or high generation LCD panel production line investment, mainly above the cruise panel manufacturers mainly, while the laser display layout is based on the downstream machine manufacturers.

In the past two or three years, laser TV has entered the fast lane of development. Besides Hisense, Changhong and other color TV brands, the layout of the TV has been accelerated, including millet, SONY, watching and micro whales.

Xu Lixin, Professor of physics at University of Science & Technology China, pointed out in an interview that China's laser display technology is comparable with foreign countries, and each has its own advantages. Foreign countries in the drive chip, semiconductor light source development on the front, and our country in the optical engine, speckle removal, light efficiency technology has certain advantages.

According to reporter understanding, Hisense laser optics engine 100% independent research and development design, 70% whole machine cost is grasped in oneself hand. Changhong is also speeding up the layout of the laser TV industry chain. In June 15th, Changhong built an adult production capacity of 150 thousand sets of laser light machines, the main integrated standard laser display production line, to speed up the development of Changhong laser display industry. And now the industry is accelerating the development of full-color laser projection technology, by using the narrow spectrum of red green and blue three primary color laser to realize laser synthesis of white light, "pan" display in the true sense. In this case, Chinese manufacturers are actively promoting full-color laser display technology applications, it is revealed that next year, Hisense will launch full-color laser tv.

Micro LED these two or three years of concern

In addition, LCD printing, laser display display, there are many companies in the development of QLED, Micro, LED holographic display technology, which Micro LED in the two or three years of concern, which is mainly affected by the acquisition of Luxvue apple company. According to deputy director China liquid crystal optical optoelectronic industry associations branch and Secretary General Liang Qingxin revealed that Apple will have Micro LED development team moved to China Taiwan, where Apple has a line from Qualcomm acquired the 4.5 generation TFT production line, the factory line is mainly used for panel analysis certification and Micro LED research and development.

In fact, our research institutions began to develop Micro LED technology very early.
