What is the LCD module, and the difference between LCD panel?

Publisher: Administrator    Date:2020-07-30

      The TN+FILM technology is to add a layer of wide viewing angle compensation film on the original basis. This layer of compensation film can increase the viewing angle to about 150 degrees, which is a simple and easy method and is widely used in liquid crystal displays. However, this technology cannot improve performance such as contrast and response time. Perhaps for manufacturers, TN+FILM is not the best solution, but it is indeed the cheapest solution, so most Taiwanese manufacturers use this Method to build a 15-inch LCD display.

      Second: The thickness of the embroidery thread should be uniform, the thickness should be just suitable for the embroidery board grid, and it should be corrosion resistant. The embroidered work with uneven thickness of embroidery thread is very ugly. If the embroidery thread is too thin, the bottom plate will be exposed, which will affect the appearance of the finished product. If it is too thick, the thread will not be drawn smoothly during embroidery. Easy to damage the embroidery board. The principle of MVA (MULTI-DOMAIN VERTICAL align MENT) technology is to increase protrusions to form multiple visible areas. The liquid crystal molecules are not completely arranged vertically in a static state. After a voltage is applied, the liquid crystal molecules are arranged horizontally so that light can pass through each layer. MVA technology increases the viewing angle to over 160 degrees and provides a shorter response time than IPS and TN+FILM. This technology was developed by Fujitsu, and currently Taiwan Chi Mei (Chi Mei is a subsidiary of Chi Mei in mainland China) and Taiwan AUO are authorized to use this technology.

      ViewSonic’s VX2025WM is the representative of this type of panel. The horizontal and vertical viewing angles are both 175 degrees. There is basically no visual blind angle, and it also promises no bright spots. The viewing angle is divided into parallel and vertical viewing angles. The horizontal angle is liquid crystal. The vertical axis is the center, moving left and right, you can clearly see the angle range of the image. The vertical angle is centered on the parallel central axis of the display screen, moving up and down to clearly see the angle range of the image.
