As an industrial-grade professional display device, LCD splicing screens are mainly used in monitoring occasions that are mainly powered on for a long time, such as monitoring rooms in public security, traffic police, banks, enterprises, communities, etc., all of which are coordinated with monitoring equipment As a safety management, because it needs to be started for a long time, the basic requirements for it are stable operation and reliable quality. How to determine the quality of LCD splicing screen.
1. The LCD splicing screen selection panel is very important. It directly affects the performance and service life of LCD splicing products, and also affects the manufacturer's brand and customer's reputation.
2. The brightness of the LCD splicing screen is an important indicator to measure the brightness of the LCD splicing screen. The higher the brightness, the more eye-catching the LCD screen. The LCD splicing screen is a material that solidifies first and then liquids. It does not emit light by itself, and its brightness is completed by the backlight tube behind the panel, so the number of lamp tubes is related to the brightness of the LCD splicing screen.
3. Contrast, this is also an important goal for measuring LCD splicing screens. When we watch a movie with character scenes, the contrast block can appear from the contrast between light and darkness.
4. From a visual point of view, with the advancement of liquid crystal technology, the visual angle of view of the LCD splicing screen has reached over 178 degrees, achieving the function of positive viewing angle.
5. If the splicing screen is used for splicing and the seams are large, it will affect the visual effect. This is unbearable for users. Now manufacturers have chosen DID LCD screens and plan to use ultra-narrow bezels with stitching gaps of only a few millimeters. Can clearly display good images.
6. The structure of the LCD splicing screen, we all know that a good LCD splicing curtain wall is composed of multiple splicing units, the form is MN, in many cases, it is not needed during the day and night. Continuous work requires the LCD splicing screen to have strong stability and reliability.
