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.

With the popularization of the construction of national smart cities and safe cities, LCD splicing screens, as the best terminal display equipment, are favored by various industries and are perfectly integrated into our lives; as we all know, the LCD splicing industry is a sunrise industry with broad development. The prospects and entry barriers are extremely low. Therefore, the LCD splicing market has attracted an influx of many manufacturers, and the actual products of manufacturers are uneven. The viewing angle of the LCD splicing screen can reach 178 degrees, while the ordinary LCD can only see the 178-degree blank space. This is a very important criterion for distinguishing LCD splicing screens and LCD monitors. There is also the difference between the input signals of the two. The splicing screen is mainly the input video signal. In order to meet the interface requirements of different front-end devices, the splicing screen interface will be much richer than the display, including BNC, VGA, RGB, HDMI, DVI, S A variety of interfaces such as terminals meet the input requirements of different signals, while the monitor mainly inputs VGA signals, and the interfaces are mainly VGA, S-terminal, etc., which cannot meet the signal input requirements of various monitoring equipment. What is the difference between an LCD splicing screen and an LCD monitor, be sure to read it clearly when buying The driving scheme of LCD splicing screen is different, that is, the display motherboard scheme is different. Since the LCD display usually takes no more
