Information

   In the current large-screen display market, LCD splicing screens are undoubtedly one of the most widely used display terminals. Shopping malls, subway stations, command and dispatch centers and other places can be seen everywhere. The expanding application range makes LCD splicing screens a veritable "public". From a sensory point of view, people are not unfamiliar with it. However, due to the enhanced professionalism of LCD splicing screens and the increasing diversification of manufacturers’ marketing gimmicks, superficial understanding is not a practical choice for industry users. Purchase indicates the direction. If you want to buy a product with high cost performance and strong applicability, the following things must be clarified.

Thickness is not an independent factor, LCD splicing screen is not as thin as possible

For a long time, in large-screen display applications, LCD splicing has been known for its ultra-thinness. Based on marketing demands, lightness and thinness have become the key packaging objects of merchants. This has also led to industry users who are concerned about the thickness of products when purchasing. ?So, in practical applications, is the LCD splicing screen really as thinner as possible?

Everything has two sides, and the thickness of the LCD splicing screen is no exception. Advantages, for example, the thinner the LCD splicing screen, the more beautiful the screen; at the same time, the thickness of the product also directly affects the response time. Related research shows that the thickness of the splicing large screen is reduced by 20, and the response speed will be improved on the original basis. 35 and so on. There are also many shortcomings that accompany it. For example, the thinner the product, the higher the requirements for the manufacturing process. Once the process fails, not only the color displayed on the screen will become dim, but the viewing angle will also become smaller. At the same time, the probability of the occurrence of dead pixels on the screen will increase, and the product yield will decrease. This means that the production cost of thin and light products will be greatly increased. "The wool is on the sheep", naturally, the application cost of the product. It will also be greatly improved.

In other words, industry users must have a higher budget to choose thin and light products, and choose large brands with guaranteed quality and after-sales service to avoid unnecessary trouble. If the budget is limited, you must not just be cheap just because you are catching up with the trend, just apply it.

LCD splicing screens will also have chromatic aberration, so you should pay attention to "rest" in daily applications

In addition to being light and thin, no color difference is also the advantage of LCD splicing screens, especially in comparison with DLP splicing screens (DLP splicing screens will have color attenuation after a period of use), but LCD splicing screens really have no color Decay? The answer is of course no. After a long period of application, LCD splicing screens will also experience color attenuation, and this attenuation is irreversible. However, at present, manufacturers already have certain adjustment methods, which is what users should pay attention to when purchasing.

In addition, it is worth noting that, although "can continue to run for 640x960 hours" is a key object in the marketing and promotion of LCD splicing screen manufacturers, but in practical applications, LCD splicing screens also need to be properly rested, otherwise it will affect the service life- Related studies have found that the LCD splicing screen will accelerate its aging when working continuously at full load for more than 96 hours, and even burn out in severe cases. In practical applications, it is best for users to allow the LCD splicing screen to rest intermittently. If conditions do not permit, try to change the display content of the screen at different time intervals so that the screen can be adjusted slightly while waiting for the working state.

The physical resolution of the LCD splicing screen cannot be adjusted, pay attention to marketing traps

Due to the display effect, the resolution of the LCD splicing screen has always been the focus of industry users, and it is also the focus of industry users when choosing products. What I want to say here is that usually the resolution of the LCD splicing screen refers to the physical resolution of the liquid crystal display, which represents the highest displayable pixel parameter of the liquid crystal display, which cannot be adjusted. The higher the physical resolution, the higher the definition of the large LCD screen.

Driven by the high-definition trend, "up to 1640x9600p resolution" has become a customary propaganda method for businesses. However, it is worth emphasizing that this only means that the LCD screen can support 1920×1080 signal input format, and the physical resolution of the panel The rate may not reach 1920×1080, and it may also be 1640×960 (the minimum resolution limit of the national high-definition display standard). If it is the latter, in actual operation, only the 1920×1080 signal needs to be converted into a 1366×768 format that conforms to the panel output through image changes and then presented to the audience. In the process, the picture display effect will be compressed and lost. Industry users must pay more attention to actual purchases.

Visual angle and wide angle of view are two different things

In the daily marketing of LCD splicing screens, wide viewing angles are undoubtedly a common target. Generally speaking, the "wide angle" in merchant marketing refers to the viewing angle of the LCD splicing screen, that is, the angle at which users can clearly observe all content on the screen from different directions. The wide viewing angle refers to the degree to which the color shift of the LCD splicing screen is. At present, because the measurement standards are not uniform, the results obtained are not the same, and it is not a specific value. At present, the viewing angle of the LCD splicing screen is above 178 degrees, which can be regarded as an absolute viewing angle.

Conclusion:

Due to the increasing popularity of LCD splicing screen applications, people often ignore the nature of their specialized products, especially because of the popularity of conceptual marketing, which makes many industry users at a loss. Therefore, before purchasing, industry users must clarify their own application needs and avoid meeting the pursuit of trends. Moreover, it is worth mentioning that the application effect of LCD splicing screens is not only related to the quality of their own products, but also reliable. The solution is directly linked to the comprehensive strength of the manufacturer, and industry users must consider comprehensively when purchasing.
