Technology:
Nippon Electric Glass that became independent of NEC in 1949 developed a substrate glass
suitable for high-definition liquid crystal panels called 4K and 8K. The new
substrate glass decreased the heat shrinkage to less than one tenth. It will
allow panel producers to boost yield. The company will establish a mass
production system shortly. A liquid crystal panel is built by attaching a film to
a glass substrate. In the case of the high-definition liquid crystal panel, the
glass mostly is heated to higher than 600 degrees centigrade. The heat
treatment is liable to generate shrinkage that cannot be modified even in the post-process.
The company solved the problem by reviewing raw materials and cooling glass
down gradually in the molding process.
The company has
started to ship samples of about one meter square. It wishes to get the first
order within the year. It has already laid down a plan to start mass production
in its two plants in Shiga
Prefecture. The amount of
capital investment is not announced. Nippon Electric Glass lately faced the
decreasing profitability because of the decreasing prices of flat-screen TVs. The
company wishes to recover the profitability by taking the initiative in the substrate
glass for high-definition TVs. Nippon Electric
Glass has a share of 20% in the world market of substrate glass for liquid
crystal panels.
