Liquid crystal materials are found in1888;
1888 ~ 1968 is the research period of the properties and applications of liquid crystal materials.
1968, the first LCD product was made in the United States;
1973 sharp domestic TN-LCD；; ;
1973 ~ 1985 was the period when TN-LCD was widely used.
STN-LCD and TFT-LCD were invented in 1984.
1985 ~ 1993 is the popularization and application period of STN-LCD.
1993 ~ 2000 is the great development period of TFT-LCD, and the performance of TFT-LCD in this period can be comparable to that of CRT.
The development of LCD has greatly expanded the application range of displays, making it possible for individuals to use mobile handheld displays. Therefore, after 2000, LCD and CRT will enter the era of competing for the mainstream market of displays.
Color low power reflective LCD technology.
Mass production technology of low temperature polysilicon liquid crystal display.
Development of color TFT-LCD with large size, wide viewing angle and high resolution. Before 1993, the main products were 10.4 inch, 640×480 pixels; 1993 ~ 1997 mainly produces 10 inch ~ 13 inch and 1024×768 pixel products; 1997 ~ 1999 mainly produces products with pixels of 15 inch ~ 18 inch, 1024×768 and above; After 1999, 20-30 inch products will be produced.
Starting from 1998, efforts were made to develop LCD projection TV with high resolution and large screen.
In 2008, people paid more attention to the beauty and thickness of LCD TV, and now the thinnest TV below 26 inches can be 22 mm
