About the bar LCD display

Development History

As an important branch, bar LCD display is widely used in many industries with its unique advantages. Its emergence is closely related to the development of liquid crystal technology. It has gone through several stages of development from the early simple digital display to the current important tool in many commercial fields.

 

The origin of liquid crystal display technology

In 1961, F. Heimeier of RCA Corporation in the United States accidentally discovered the electro-optical effect of liquid crystal while studying the effect of external electric field on the internal electric field of crystal. He successfully developed a series of digital and character display devices, as well as practical products such as liquid crystal display clocks and dashboard displays. This discovery laid the foundation for the commercial application of liquid crystal technology.

Principles of LCD display technology

 

Breakthrough and commercialization of liquid crystal technology

In 1970-1971, Swiss Roche and Kent State University in the United States developed TN-LCD technology, which solved many problems in liquid crystal display and promoted the commercialization of liquid crystal display. In 1984, Japan's Epson launched the world's first color LCD product - the ET-10 pocket TV with a screen size of 2 inches and TN TFT-LCD technology. During this period, liquid crystal technology began to be widely used in small electronic devices, laying the foundation for subsequent diversified development.

 

The birth of bar LCD display
