Matrix liquid crystal display is a high-tech display technology. It uses transistor array as the control unit, which can control a large number of pixels at the same time. Matrix LCDs are used in a wide range of modern electronic devices, including smartphones, televisions, computer monitors, and more.

Manufacturing matrix liquid crystal displays requires a variety of high-tech technologies, including optics, electronics and materials science. Among them, the following three technologies are the most critical.

 

1. LCD external transistor array: The external transistor array of matrix liquid crystal display is the precise control unit of each pixel. brightness and color. The external transistor array process requires exquisite electronic device manufacturing technology, including multiple steps such as lithography, evaporation, cleaning and etching, and requires the size and position of each transistor to achieve sub-micron precision.

2. LED backlight: The matrix LCD needs a backlight to illuminate the pixels to display the picture. In recent years, with the development of LED (Light Emitting Diode) technology, LED has replaced the traditional fluorescent tube backlight, which has the advantages of low energy consumption, pure color, and long life. LED backlight needs to be manufactured by surface mount technology (SMT), and at the same time, it needs to be optimized for luminous efficiency and light field distribution.

3. Liquid crystal material and driving circuit: The liquid crystal material and driving circuit of matrix liquid crystal display are the key factors affecting the quality and performance of the screen. The orientation and change of the liquid crystal molecules are controlled by the electric field, and the driving circuit needs to be designed according to the characteristics of the liquid crystal material. Most modern matrix LCDs use different types of liquid crystal materials such as IPS (wide-angle field of view) or VA (high contrast), and use digital driving methods to achieve more precise pixel control and higher refresh rates.

 

To achieve precise control of high-pixel screens, optimizations such as pixel wiring and correction techniques are also required. For example, for the accuracy error caused by pixel wiring, methods such as electrical trimming and pixel selection can be used to correct. At the same time, technologies such as color correction and grayscale correction can also be used to improve the color accuracy and picture clarity of the screen. The continuous breakthrough and innovation of these technologies and methods will help the continuous development and progress of matrix liquid crystal displays.

In short, the manufacture of matrix liquid crystal displays requires the use of a number of high-tech technologies, including LCD external transistor arrays, LED backlight sources, liquid crystal materials, and drive circuits. Through the continuous improvement and improvement of these technologies, the matrix LCD will be able to achieve more precise pixel control and higher picture quality, providing strong support for the further development of modern electronic equipment.
