Not long ago, through continuous technical breakthroughs, Changhong Group, which had produced China's first CRT picture tube, succeeded in trial production of LCD substrate glass for liquid crystal displays.
Senior Engineer Xue Xinjian of Shaanxi Changhong Electronic Glass Co., Ltd. said that after inspection, all the performance indexes of the glass substrates they produced fully satisfied the requirements of LCD panel production. At present, only a few companies in the world can produce this type of glass.
LCD substrate glass is different from ordinary glass; it requires a very high thermal expansion coefficient and insulation performance. Enterprises in developed countries that master this technology have utilized patent protection to set up numerous technical barriers for Chinese enterprises.
