What is the production process of LCD?

although LCD is widely used.
its production is a process of very complex technology and high precision, 2 m + n / T! D8 _ 1 D9 H6 [7 q.
       A few days ago, I had the honor to accept the invitation of Mingji to visit the production line of the world's third largest TFT-LCD Youda optoelectronic Suzhou module factory.
I have a certain understanding of the "assembly" process of LCD panel. If there is anything wrong, please criticize it by readers and experts.

      The so-called "module" factory (LCM) is actually the "later stage" production process of LCD.
as the name suggests, the word "module" is module combination, which has three steps:

       In a word.
compared with the skyrocketing investment (billions of dollars), amazing floor area (at least five football fields) and numerous sophisticated equipment (all listed in the US embargo on the mainland), the module factory is still very small in technology and scale, but it is also a great pleasure to enter the dust-free workshop with one's own eyes, It's not necessary to take a bath for self-cultivation, but all electronic devices, including digital cameras and mobile phones, need to be shot.

       Before showing the whole production process with pictures.
let's first understand the working principle of LCD panel, which can deepen our understanding of the factory.

the liquid crystal display screen drives the liquid crystal molecules between the glass and the filter through the electric field formed by the circuit on the silicon glass, which are arranged in parallel in the natural state. When the electric field is applied to the liquid crystal layer by the circuit, the liquid crystal molecules will deflect in different directions. At this time, the liquid crystal is similar to the switch function, which can let the light pass through and make the liquid crystal layer form different light transmission effects, So as to display different pictures.,.
