5. LG Electronics
In 200 1 year, LG Electronics and the Display Research Institute of LG Institute of Technology jointly developed a 5-6 inch FED. In 2002, 20-inch field emission display was successfully developed, and there are plans to commercialize FED.
6.ITRI Institute of Electronics
In August, 20001year, the Institute of Electronics of ITRI announced the development of the first 4-inch carbon nanotube factory emission display (CNT-FED) in Taiwan Province, which is beneficial to the low conduction electric field, high emission current density and high stability of carbon nanotubes. At the same time, the combination of FED technology can realize the planarization of cathode ray tube, which has the advantages of power saving and small size, and becomes a large-size flat panel display with low driving voltage and high luminous efficiency.
In addition to the application of carbon nanotube field emission technology in displays, ITRI Electronics Institute also announced the completion of the development of 20-inch carbon nanotube field emission backlight unit (CNT-Blu) in February 2004, which is mainly used for the backlight of large-size TFT LCD. At present, the backlight module of large-size TFT LCD still uses cold cathode tube (CCFL) as the backlight. However, the CCFL used in large-size (more than 30 inches) TFT LCD needs to be longer, which is more difficult to produce than the picture tubes used in notebook computers and monitors. Moreover, the cost of large-size TFT LCD backlight module is greatly increased due to the problems of picture uniformity, mercury content and expensive optical film. Although many manufacturers are developing in the direction of LED backlight module, the application of carbon nanotube field emission technology in the development of backlight module has the advantages of uniform light source intensity, high luminous efficiency and simple process, which will make carbon nanotube field emission technology have an additional application direction.
7. Dongyuan nanomaterials
In 2002, Dongyuan Group signed cooperation projects with Institute of Electronics, Institute of Materials and Institute of Chemical Industry on carbon nanotubes related materials and products. Dongyuan will make use of the basic research in nanotechnology by the Institute of Heavy Industry and the commercial development of Dongyuan to develop carbon nanotube displays for TV.
In 2002, Dongyuan Nano Materials, a subsidiary of Dongyuan Group, received a subsidy of 30 million yuan from the Ministry of Economic Affairs, and Dongyuan Group invested in the research and development of carbon nanotube displays and related materials. In addition to borrowing money from the Institute of Heavy Industry, he has also conducted personal research projects with universities such as National Taiwan University, National Taiwan University, Jiaotong University, Huazhong University and Chung Yuan Christian University.
8. Others
For other manufacturers, mitsubishi electric has developed a carbon nanotube field emission display, which is expected to be commercialized in 2006. Motorola Laboratories of Motorola R&D announced in July 2003 that they had completed the technology of carbon nanotube field emission display and showed a sample of 15 inch. However, Motorola does not intend to build its own factory to produce FED, and plans to open technology patents to interested manufacturers.
Canddescent Technology D built a 340,000-square-foot factory in San Jose, California. However, due to technology and market demand, it announced that it would abandon the production plan of the display of the field shooting team and prepare to authorize the technology to other companies, which will transform from a manufacturer to a company with intellectual property rights.
Home appliance manufacturers choose unique technology to strengthen their competitiveness.
In terms of large-size thin TV technology, LCD TV, plasma TV, rear projection TV and emerging SED TV, major home appliance manufacturers gradually think that with their own unique technology, they can provide full support in terms of cost, image quality and production capacity in the fierce competition, so the development of Japanese display manufacturers has recently shown a trend of {selection and concentration}. For example, Sharp announced the construction of the seventh-generation factory after the mass production of the sixth-generation factory. Samsung and LG. Philips LCD also announced plans to build a seventh-generation factory, while Hitachi transferred the plasma display manufacturing company FHP from Fujitsu Group to its own group, and cooperated with Panasonic in the research and development, manufacturing technology and parts procurement of plasma displays. Although Sony denies quitting the operation of plasma TV, it also emphasizes that LCD TV and rear projection TV are the main technologies developed. Therefore, under this wave of {selection concentration}, manufacturers have their own unique technologies.
