  •   Analysis of precautions when buying LCD splicing screen: 
  •  
  • 1. LCD splicing screen physical resolution
  •  
  •      As we all know, the sharpness of the display is determined by its resolution. The higher the resolution, the clearer the picture. Many LCD display products on the market have reached 4K resolution, but as far as splicing screens are concerned, only 1920 * 1080p resolution can be achieved. Common splicing screen resolutions on the market are still 1366 * 768p or other. Always pay attention.
  •  
  • 2. The distinction between viewing angle and wide viewing angle
  •  
  •      Generally, in the marketing of LCD splicing screen manufacturers, the wide angle refers to the angle at which users can clearly view the screen display content, that is, the viewing angle. The wide viewing angle refers to the problem of color cast of the LCD splicing screen. However, many users do not understand and the marketing of the business is easily confused by the two concepts. At present, the viewing angle of the LCD splicing screen on the market has basically reached 178 °.
  •  
  • 3. Continuous use time of LCD splicing screen
  •  
  •      Although many manufacturers have always said that the LCD splicing screen can work continuously for 7 * 24 hours, it is necessary to know that the full-load working time of the liquid crystal molecules is 96 hours. Long-term use may cause the liquid crystal molecules to age or even burn out. As a result, the entire LCD splicing screen is damaged. Therefore, the LCD splicing screen should not be used for a long time, but needs appropriate rest.
  •  
  • 4. Openness and scalability of the system
  •  
  •      In addition to direct access to VGA, RGB, and video signals, the system should also support access to network signals, broadband voice, etc., and can switch various types of signals to provide users with an interactive platform; the system should include new equipment and new Functions can be expanded at any time; the software can support online upgrade without having to modify the source program.
  •  
  • 5. Whether the after-sales service is perfect
  •  
  •      Many unscrupulous merchants recycle old machine parts for refurbishment or install them with second-hand LCD panels. Many problems will occur after a period of use, and at this time the merchants have disappeared. Therefore, it is very important to choose a merchant with perfect after-sales service. Generally, the merchants with good after-sales service will not be worse.
  •  
  •      The LCD splicing screen has a long service life and low cost. The LCD splicing technology is also a mature display technology. There are no wearing parts and consumables, and there is no need to maintain the large screen on a regular basis, which saves a lot of costs, so it is welcomed by a large number of users.
