the situation totally dependent on imports

The Microtek, the HP, AGFA, the UMAX, Acer, EPSON Canon and other long have moved into China's domestic market, at the same time, the production base of OEM manufacturers in Taiwan are all transferred to the mainland, Beijing University Founder, Tsinghua Unisplendour domestic unit of R & D scanners are becoming an important brand in the scanner market. Optical display materials and equipment (circuit basis, analog circuits, digital circuits, Microcomputer Principle and Interface Technology, optical, etc.). The mutual inspection is also the important quality inspection of  laser pointer . The name of this kind of  laser pointer  is super bright green laser pointer
Monitor developments in the field in China: in the liquid crystal display (LCD): China's LCD monitor production accounts for 25% of world production. China LCD industry with annual sales of about 5.352 billion yuan. China has been able to produce to meet the special requirements of the wide temperature low threshold of TN liquid crystal material, has begun mass production of the STN liquid crystal material, the end of the situation totally dependent on imports. The domestic film transistor (TFT) liquid crystal material is still in laboratory development phase. The annual production capacity of liquid crystal materials in China has more than 40 tons. There are four major domestic enterprises: Beijing Tsinghua sub-king of Liquid Crystal Materials Co., Ltd., Xi'an Modern Chemistry Research Institute, Shijiazhuang strength g LCD and Yantai Valiant Fine Chemical Co., Ltd.. So that this kind of  laser pointer is portable to carry around easily.
Polarizer has entered a stable stage of mass production, the existing two production companies, co-polarized Devices Co., Ltd., Guangdong Fortune Shenzhen Textile Lucky Optoelectronic Materials Co., Ltd., with annual sales of 750,000 square meters, with sales of more than 60 million million. ITO conductive glass is the fastest LCD among the three materials development, the manufacturer has more than 10, the largest of these is the Shenzhen Leybold Vacuum Technology Co., Ltd..
