In our daily life, 80% of information comes from vision. Therefore, the research and development of display technology has always been valued by enterprises, scientists and engineers all over the world.

This week ,  brief history of liquid crystal industry technology will be introduce to you.

There will be 4 parts about the theme, meet you every Tuesday.

Here we go:

In 1960s, polymorphic scattering liquid crystal was found in safnor center of RCA company and twisted nematic liquid crystal display (TN-LCD) was found in Westinghouse.

In the 1970s, Brody invented the active matrix liquid crystal technology; sharp of Japan obtained the license of dynamic scattering liquid crystal technology from RCA. STN-LCD technology has been developed and applied in Japan (laboratory stage).

In the 1980s, tn-stn simple matrix developed to TFT-LCD (electronic watch, calculator).

From 1990 to 1995, Japanese enterprises built the first and second generation TFT-LCD lines; in 1992, amorphous silicon TFT-LCD color screens appeared (electronic watch, calculator, LCD TV prototype).

In 1996, Japan developed low-temperature polycrystalline silicon liquid crystal; Japanese enterprises started to build the third generation line of TFT-LCD.

In 2000, South Korea and Taiwan took the lead in building the 4G line, replacing Japan's dominance (laptop).

In 2002, Korean and Taiwan enterprises started to build 5g line, while Japanese enterprises did not invest in 5g line (desktop display / notebook / mobile phone).

In 2004, sharp built its first 6-generation line.

In 2005, Samsung built its first 7-generation line (LCD TV).

In 2006, sharp built its first 8-generation line.

In 2009, sharp built the first 10 generation line (large size LCD TV).
