What Is The Difference Between LCD Module LCM And LCD Panel?

  The liquid crystal module (LCM) is simply a liquid crystal screen and a backlight assembly. For example, the display component of a liquid crystal television is a liquid crystal module, and its low temperature is equivalent to a picture tube in a CRT. Other parts include power circuits, signal processing circuits, and of course, housings.

  The liquid crystal module is mainly divided into a screen and a backlight assembly. The two parts are assembled together, but they are independent of each other at work. The principle of the liquid crystal display is that the backlight assembly emits light, and the light is displayed through the liquid crystal screen. The function of the LCD screen is to control the light by pixels to display the image.

  The liquid crystal panel is the main component of the liquid crystal display, accounting for nearly 80% of the cost of the liquid crystal display. At present, there are not many manufacturers of panel manufacturing technology in the world. Only SHARP (Sharp), Samsung, LGD, Taiwan Innolux, AUO and other manufacturers have core technologies. Most of the terminal manufacturers in the past use their LCD panels. Of course, with the rapid development of mainland panel manufacturers, domestic companies such as BOE, Shenzhen Tianma, Huaxing Optoelectronics, etc. have begun to accumulate their own patented technology, and the panels produced by them have also been widely adopted by terminal manufacturers.

LCD panel specification level

   The so-called dead point is the general name of the pixel on the liquid crystal panel. The liquid crystal panel is composed of a plurality of pixel points, and the liquid crystal substance at each display point is changed under the control of the electric signal to change the light transmission state. At 1024*768 resolution, there are 786,432 display points on the LCD panel. It is difficult to ensure that individual problems will occur. At present, the technology cannot completely overcome the situation without dead pixels. Therefore, the hierarchical division of the panel is also judged according to the number of bad points. Manufacturers generally avoid the bad point split LCD panel, and sell LCD panels with no bad points or few bad points at high prices, while the number of bad points is relatively low.
