[China Glass Network] With the popularization of national smart cities and safe cities, LCD splicing is a better terminal display device that is favored by various industries and perfectly integrated into our lives. It is well known that the LCD splicing industry is a sunrise industry. With a broad development prospect, the threshold for its entry is extremely low. Therefore, the LCD splicing market has attracted a large number of manufacturers. The manufacturers are very different. Many small manufacturers often get cheaper and cheaper in order to get more profits. There is no corresponding technology and after-sales guarantee to make the users of the company miserable; now Bobangcheng as a well-known brand in the LCD splicing industry to do a simple analysis of the excellent and inferior LCD splicing screen products, so that users can purchase LCD splicing screen products can be more Good distinction.
1, the difference between LCD splicing screen
From the level of the LCD screen, the liquid crystal display uses a civilian display, while the regular LCD splicing screen uses a high-brightness industrial grade A+ LCD screen, which requires higher backlighting than the display, so when the liquid crystal display is on display The picture will be faint, but not a good image.
2, the difference in viewing angle
The viewing angle of the LCD splicing screen can reach 178 degrees, while the ordinary liquid crystal display can only see a blank in the direction of 178 degrees. This is a very important criterion for identifying LCD splicing screens and liquid crystal displays. 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 interface of the splicing screen will be much richer than the display. There are BNC, VGA, RGB, HDMI, DVI, S. Terminals and other interfaces to meet the input requirements of different signals, while the display mainly inputs VGA signals, the interface is mainly VGA, S terminal, etc., can not meet the signal input requirements of various monitoring equipment.
3, the difference between the drive program
That is to say, the display board solution is different. The driver board of the splicing screen mainly deals with dynamic images. The liquid crystal display usually does not exceed 8 hours when the boot time is used, and the display board of the civilian level is used, and the LCD splicing screen requires It takes 24 hours a day to work 365 days, so you must use a professional monitoring board to ensure high brightness contrast and high temperature resistance, which will reduce the loss of screen usage. If the ordinary display is used for a long time, its brightness and contrast will drop rapidly, affecting its service life. This is why most LCD monitors can display images normally after the project has just been debugged, but some screens will appear dark after a continuous boot.
4, the difference in price
The formal LCD splicing screen and LCD display have a certain price difference. The professional splicing screen adopts hardware shell, new A+ industrial LCD screen and professional monitor drive board, so the cost is much higher than the display. Now there are many on the market. Low-cost LCD splicing screens, in fact, are all modified by the monitor. Basically, it can be said that the display is replaced by a shell. It is even possible to use the old screen. Please pay attention to the engineering and dealer purchasers, and try to choose a well-known brand in the industry. Emperor Ai is a good choice.
