The liquid crystal originated in 1888. It is a special mixture substance discovered by the Austrian botanist Leniz. This substance is between solid and liquid under normal conditions. Not only that, it also has the dual characteristics of both solid and liquid substances, so it is called liquid Crystal. The composition of liquid crystals is an organic compound, which is composed of carbon as the center.
In 1963, William of RCA found that liquid crystals deflected by electric field and refracted when light was injected into liquid crystals. In 1968, five years after William discovered that light can be refracted by liquid crystals, RCA's Heil Oscillator Development Department published the world's first screen that uses liquid crystal characteristics to display pictures. It took Leniz 80 years to discover the liquid crystal substance that the two proper terms "liquid crystal" and "display" were linked together, and "liquid crystal display (LCD) became the professional term of the industry.
Of course, the liquid crystal display (LCD), which first appeared in 1968, is not stable, and it is still a long way from the practical application of daily life. It was not until 1973 that Professor Gray of the University of England discovered that biphenyl could be used to make LCDs that LCDs could be manufactured in an official quantity.
This product provided a screen for EL-8025 computer of SHARP Company in Japan. Since then, many applications of liquid crystal have been opened, and the rise of LCD industry has gradually been promoted.
