What should I pay attention to when purchasing LCD splicing screens? With the development of the times, LCD splicing screen technology has made a breakthrough development, so LCD splicing screens are widely used in security, exhibition halls, transportation, education and other industries, more and more LCD splicing screens gradually appear in human vision Among them, the technology of splicing screen has matured, and there are many bad manufacturers in the market who use the various means to shoddy and deceive consumers. So what are the things to pay attention to when buying LCD splicing screens? Next, let's share with you:

1. Is the thickness of the LCD splicing screen as thin as possible?

  According to the use of large-screen display devices in recent years, LCD splicing screens are one of the lighter and thinner display products, and LCD splicing screen manufacturers also use light and thin as the key packaging objects of marketing, resulting in many users purchasing LCD splicing. The first factor in the screen is its thickness, but is the LCD splicing screen really thinner?

  Although the reduction of the thickness of the LCD splicing screen will increase its response speed, everything has two sides. The thinner the splicing screen, the higher the requirements for the manufacturing process. If the manufacturing process is not too close, the color of the screen display will be very dim. The viewing angle will also be narrowed and the chance of a dead pixel on the screen will increase, which means that the manufacturing cost of the LCD splicing wall will be greatly improved. Therefore, when purchasing a liquid crystal splicing screen, you can consider a thin and light LCD splicing screen when the budget is sufficient. If the budget is insufficient, you should choose a perfect after-sales service and apply it.

2. Is the physical resolution of the LCD splicing screen adjustable?

  The resolution of the splicing screen has always been a key concern for users and a key consideration for users to purchase LCD splicing screens. Usually the resolution of a large screen splicing screen is determined by its physical resolution. The higher the resolution, the clearer the content displayed on the screen. However, the physical resolution of the liquid crystal splicing screen currently on the market is not adjustable. Usually the resolution of the LCD splicing screen is determined when the LCD panel is in the mall panel. At present, the most common resolutions on the market are 1920x1080p and 1366x768p (the minimum resolution limit of the national HD display standard), so you must pay attention to distinguish when selecting the splicing screen.

3. Is the viewing angle equivalent to a wide viewing angle?

  In the daily LCD splicing screen marketing, the viewing angle and wide viewing angle are the most confusing for the user. Usually in the marketing of LCD splicing screen manufacturers, the wide angle refers to the viewing angle of the LCD splicing screen, that is, the user can clearly view the screen display content. Perspective. The wide viewing angle refers to the color cast of the LCD splicing screen. However, many users do not understand the marketing gimmicks of other merchants and confuse the two. The artificial angles are only the viewing angle of the LCD splicing screen. The viewing angle of the LCD splicing screen on the market basically reaches 178°.

4. Can the LCD splicing screen be used continuously for 7x24 hours?

  As a marketing method for LCD splicing screen manufacturers, it is usually said that the LCD splicing screen can work continuously for 7*24 hours, but in actual use, the LCD splicing screen still needs proper rest. For a long time, the LCD splicing screen can be used. The service life has a certain impact, especially in the process of using, it should avoid displaying the same picture for a long time to avoid the occurrence of dead pixels due to uneven heating. The full-load working time of the liquid crystal molecules is 96 hours. If used for a long time, the liquid crystal molecules may be aged or even burned, resulting in damage of the liquid crystal splicing screen as a whole, so the liquid crystal splicing screen needs proper rest in the engineering used. .

5. See if there is after sales service

  Old machine modification Shenzhen electronic market is full of many second-hand recycling products, they will take some of the old machines used by users, get back to their own renovation. Or use the second-hand LCD panel modification, the user may not see the problem when they first use it, but the use time is not long, there will be various problems, and at this time the merchant has long disappeared and escaped. How to do it? Localization service is very important. Now the information is so developed, the price of Shenzhen is not much different from the local one, and most of them are a problem of transportation costs.

6. System openness and scalability

  The digital network ultra-narrow-edge intelligent LCD splicing system follows the principle of open system. In addition to direct access to VGA, RGB, and video signals, the system should also be able to access network signals, broadband voice, etc., and can switch various types of signals at any time. And dynamic integrated display, to provide users with an interactive platform, and support secondary development; the system should have the ability to add new equipment and new features, making hardware expansion is very simple. At the same time, the software only needs to be expanded and upgraded to meet the requirements without having to modify the source program. Both the system hardware and the software can be easily "advanced with the times."

  The above items about the purchase of LCD splicing screens need to be noted here, the LCD splicing technology is a mature display technology. There is no wearing parts and consumables in the LCD splicing technology. It is not necessary to regularly maintain the large screen and save maintenance costs, so the application will become more and more extensive.
