The competition pattern is relatively stable. Although the share of Japanese enterprises in the semiconductor equipment industry is decreasing, Japanese enterprises still maintain a dominant position in some other segments of semiconductor industry and semiconductor materials. The main producers in DRAM field are Samsung, Hynix and micron (including the original Japanese Elpida acquired); the NAND field is Toshiba (a four day factory jointly invested with SanDisk), Samsung and micron; the semiconductor manufacturing equipment is Tel, screen, Hitachi high tech, etc.; the semiconductor materials...

Core point of view:1. Japan's semiconductor industry: to build a global semiconductor center through the integration of "government industry and learning"The global semiconductor industry originated in the United States in 1950s, and completed the first industrial transfer from the United States to Japan in 1970s-1980. During the period of industrial transfer, Japan was led by the government, and enterprises and research institutions worked together to achieve huge technological achievements. Under the advantages of cost and technology, Japanese enterprises took the opportunity to grow and exp...

1. Working principle of polarizerPolarizer is called polarizer, which can control the polarization direction of a specific beam. When the natural light passes through the polarizer, the light whose vibration direction is perpendicular to the passing axis of the polarizer will be absorbed. Only the polarized light whose vibration direction is parallel to the passing axis of the polarizer will be absorbed.There are two polarizers attached to both sides of the glass substrate in the liquid crystal display module. The lower polarizer is used to convert the light generated by the back light source ...

Substrate glass is one of the important raw materials for liquid crystal panel. The key structure of the LCD panel is similar to a sandwich, with two layers of "bread" (TFT substrate and color filter) and "jam" (liquid crystal). Therefore, two pieces of glass are needed to make a TFT-LCD panel, which are used as the bottom glass substrate and color filter substrate respectively.Substrate glass accounts for about 20% of the cost of TFT-LCD raw materials, which has a huge impact on the performance of panel products. The resolution, transmittance, thickness, weight, visual angle and other indicat...
