What is the difference between LCD splicing screen and other commercial LCD displays
In order to better observe the overall situation of the area, now we have installed display equipment in production and life. Take LCD splicing screen for example, it is widely used in various industries and has been integrated into people's life. But what is the difference between LCD splicing screen and other commercial display LCD devices? Let's analyze it in detail.
1. Price difference
There is a certain gap in the price between regular LCD splicing screens and LCD displays. Most professional splicing screens adopt hardware shell, new a + industrial LCD screen and professional monitoring drive motherboard, so the cost is much higher than that of the display. At present, many low-cost LCD splicing screens in the market are actually modified from the display. Basically, it can be said that the display changes the shell, It is even possible to use the old screen. Please pay attention to distinguish it by engineers, dealers and purchasers.
2. Differences between LCD screens
In terms of the level of LCD, the LCD adopts civil display, while the formal LCD splicing screen adopts high brightness industrial grade A + LCD, which has higher requirements for backlight than the display. Therefore, when the LCD is on the display screen, it will be virtual and can not achieve good image effect.
3. Visual angle difference
The visual angle of LCD splicing screen can reach 178 degrees, while ordinary LCD can only see a blank in the direction of 178 degrees. This is a very important standard to distinguish LCD splicing screen and LCD. In addition, the input signals of the two are different. The splicing screen mainly inputs video signals. In order to meet the interface requirements of different front-end devices, the interfaces of the splicing screen will be much richer than those of the display. There are many interfaces such as BNC, VGA, RGB, HDMI, DVI and s terminals to meet the input requirements of different signals. The display mainly inputs VGA signals, and the interfaces are mainly VGA and s terminals, It can not meet the signal input requirements of various monitoring equipment.
4. Differences between driving schemes
In other words, the scheme of the display motherboard is different. The driving motherboard of the splicing screen is better in processing dynamic images. The LCD generally uses a civilian level display motherboard because the startup time is no more than 8 hours, while the LCD splicing screen has to bear the workload of 24 hours a day for 365 days, Therefore, a professional monitoring motherboard must be used to ensure high brightness, contrast, clarity, ultra-high temperature resistance, etc., so as to reduce the use loss of the screen. If an ordinary display is used for a long time, its brightness and contrast will drop quickly, affecting its service life. This is why most LCD displays can display images normally after the project has just been debugged, but some screens will darken after continuous startup for a period of time.
It is precisely because in recent years, with the continuous expansion of the application of LCD splicing screen, the continuous reduction of price and the overall improvement of cost performance, the application of splicing screen in various fields has been expanded and popularized, replacing the traditional LCD and becoming the best choice in the fields of security and commercial display.
