Industrial LCD Panels According to the materials used, the backplane process is mainly divided into three types: a-Si amorphous silicon material, LTPS low temperature polysilicon and oxide metal oxide. If only from the material price comparison, the cost of amorphous silicon material is the lowest, followed by low temperature polysilicon, and oxide metal oxide is the most expensive.
LCD The factory has made frequent moves in the field of oxide backplane technology in small and medium-sized fields, and has firmly entered the high-end display industry.
However, since the backplane produced by the metal oxide process has the greatest impact on electron mobility, it can enable LCD panels with sharper image quality or larger areas, build more sensitive intracellular touch technology, and support active Matrix Organic Light Emitting Diode (AMOLED) technology, this technology is valued by many companies in the world industry.
According to the "Daily Industry News" report on March 9, 2015, Sharp, which mainly promotes metal oxide process igzo liquid crystal technology, will launch in June this year, and will launch igzo liquid crystal panel products equipped with intracellular touch technology in June. The target market is Chinese smartphone makers. They hope to improve the competitiveness of the LCD panel business through this product, and continue to stabilize and expand Sharp's share in China's high-end mobile phone market. Huadong Technology announced on March 10, 2015 that the world's first generation 8.5 metal oxide process TFT-LCD production line built by Nanjing CEC Panda Flat Panel Display Technology Co., Ltd. (hereinafter referred to as flat panel display) was put into production on March 10, 2015. , the designed annual production capacity is 720,000 glass substrates (2200mm × 2500 mm), which can produce mobile phones, tablet computers, notebook computers and monitors. It is said that 70% of the five categories of products including TV panels will be used in small and medium-sized displays Screen.
On March 13, 2015, according to a report by the Great Wisdom News Agency, relevant insiders of BOE a learned that recently, the 8.5th generation TFT-LCD production line of BOE Chongqing lighted up the first product. Construction of the production line started in July 2013, creating the fastest pace in the global industry in just 17 months from piling construction to product lighting. Mass production is expected to begin in the second quarter of 2015. BOE Chongqing's Gen 8.5 TFT-LCD production line has a designed capacity of 90,000 glass substrates per month. The project uses metal oxide technology to make the backplane, which can build in-battery touch function, and has core technologies such as BOE's independent adsds wide-angle.
According to previous news, BOE`s Hefei Optoelectronics sixth-generation line has a 2K metal oxide capacity, and Hefei Xinsheng Optoelectronics` eighth and fifth-generation lines also have 5K metal oxide capacity.
The National Development and Reform Commission and the Ministry of Industry and Information Technology issued the "2014-2016 New Display Industry Innovation and Development Action Plan" on March 16, 2015, requiring a comprehensive grasp of low-temperature polysilicon (LTPs) / metal oxide liquid crystal displays ( LCD) and Active Matrix Organic Light Emitting Diode (AMOLED) technologies. After mass production, the annual production capacity will reach 5 million square meters and 2.4 million square meters respectively. The goal is to reach the second largest scale in the world on the basis of more than 300 billion yuan, with a global market share of more than 20% and an overall industrial scale of more than 20%.
