Knowledge point:
The production distribution of LCD screens in the world
Introduction
LCD screens have become an integral part of our daily lives, from televisions and computer monitors to smartphones and tablets. The production and distribution of LCD screens involve a complex global supply chain that spans several countries. In this article, we will explore the manufacturing process of LCD screens and the key players involved in their distribution.
The Manufacturing Process
The production of LCD screens involves several intricate steps that require advanced technology and precision. Here is a simplified overview of the manufacturing process:
1. Substrate Preparation: The process begins with the preparation of glass substrates, which serve as the foundation for the LCD panel. These glass substrates are meticulously cleaned and polished to ensure a smooth surface.
2. Thin-Film Transistor (TFT) Fabrication: A thin layer of amorphous silicon is deposited onto the glass substrate. This layer is then patterned to create an array of transistors, which control the individual pixels on the screen.
3. Color Filter Fabrication: On a separate glass substrate, a color filter is created using a photolithography process. This filter consists of red, green, and blue sub-pixels, which combine to produce the full-color display.
4. Liquid Crystal Alignment: The two glass substrates, one with the TFT array and the other with the color filter, are aligned together. A layer of liquid crystal material is then sandwiched between them. The liquid crystal molecules align in a specific direction to control the passage of light.
