Liquid crystal display (LCD) is a kind of display using liquid crystal as material.   What is liquid crystal? In fact, liquid crystal is a kind of material between solid and liquid. When heated, it will appear transparent liquid, and when cooled, it will crystallize into chaotic solid. Liquid crystal is an organic compound with regular molecular arrangement.   According to the different arrangement of molecular structure, liquid crystals can be divided into three types: Smectic liquid crystals similar to clay, Nematic liquid crystals similar to thin matchstick and Cholesteric liquid crystals similar to cholesterol.   The physical properties of these three kinds of liquid crystals are not the same. Nematic liquid crystals of the second kind are used in liquid crystal displays. The molecules are long rods. In the natural state, the long axes of these long rods are roughly parallel.

With the support of policies and funds, China has become the largest LCD panel supply market in the world. According to the statistics of China Business Industry Research Institute, China’s panel production capacity accounted for about 29% in 2016, and it is expected that China’s panel production capacity will account for 56% by 2022.   LCD panel is promoted by policy, technology and capital The LCD panel industry is capital intensive, labor-intensive, and driven by market demand. The development of panel enterprises needs policy support, technology development and capital investment. LCD panel cycle weakened, the profitability of manufacturers increased significantly Due to the two-year construction period and one-year capacity climbing period, the past LCD panel showed a strong periodicity. As the industry enters the late stage of maturity, the willingness of manufacturers to build new production capacity is greatly reduced. According to our supply and demand model, the compound growth rate of LCD production capacity in the next three years will be 3.1%; The compound growth rate of LCD demand side is about 6.5%, the supply and demand pattern of the industry will be improved, the periodicity will be significantly weakened, the panel price will be maintained in a reasonable range, and the profitability of LCD panel manufacturers will be greatly improved. LCD panel has entered the era of China, and the panel “two heroes” take off The display panel industry is a key industry supported by the state, and the state has issued a number of policies to support

Resolution Resolution is a very important performance indicator. It refers to the number of points that can be displayed horizontally and vertically on the screen (lines and planes on the screen are composed of points). The higher the resolution, the more information can be included in the same screen. 480×800 resolution and 320×240 resolution are perfect display. Because there is little difference between the two, but the maximum resolution is not necessarily the most appropriate resolution. If 480×8000 LCD is used in 320×240 LCD, the display content will be smaller.   Visual area of LCD It refers to the part of the display area that can be used to display the image in practical application. The full size is actually the size of its frame and PCB board, and the part that can be used to display images does not reach this size at all, because the frame takes up some space. Generally speaking, the area of 4-inch 480×800 LCD is 51.84×86.4mm, and that of 3.5-inch 320×240 LCD is 70.08×52.56mm. But for LCD, the size of area is basically the size of the visible area, and the space occupied by the frame is relatively small. The 4-inch 480×800 LCD has a display area of 51.84 * 86.4mm.So choose LCD screen, choose suitable for your own equipment.   Reaction speed The unit of time used to measure reaction speed is millisecond (ms), which is the time required for a pixel to go from light to dark and from dark to light.
