Sensory speaking, people are not unfamiliar to them. However, due to the increased professionalism of LCD splicing screens and the increasing diversification of manufacturers' marketing gimmicks, the understanding of the surface cannot be specified for the actual purchase by industry users. . If you want to buy a product with high cost performance and strong applicability, pay attention to the following points:
Thickness is not an independent factor, LCD is not as thin as possible
All along, in large-screen display applications, LCD splicing has been known for its ultra-thin stencils. Based on its marketing appeal, thin and light has become a major packaging target for merchants. This has led to the attention of the industry users when they are paying attention to the thickness of products. So, in actual applications, the LCD is really the thinner the better?
Everything has two sides, the thickness of 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 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 increased on the basis of the original. 35 and so on. There are also many short boards associated with them. For example, the thinner the products, the higher the requirements for the manufacturing process. Once the process is closed, not only the color of the screen display will become dim, but also the viewing angle will become smaller. At the same time, the chances of bad spots appearing on the screen will increase, and the product yield will decrease. This means that if you want to produce light and thin products, the production cost will increase significantly. “Wool is on the sheepâ€, naturally, the application cost of the product It will also increase dramatically.
In other words, the industry users must choose a thin and light product with a higher budget, and choose a large brand with guaranteed quality and after-sales service to avoid unnecessary trouble. If the budget is limited, it must not be because of catching up with the tide.
LCD splicing screen will also have color, daily applications should pay attention to "rest"
In addition to light and thin, no color difference is also an advantage of LCD splicing screens, especially in comparison with DLP splicing screens (DLP splicing screens will fade after being used for a period of time), but LCD splicing screens have no color Attenuation? The answer is of course no. After a long period of application, the liquid crystal splicing screen will also appear color attenuation, and this attenuation is irreversible, however, at present, manufacturers have some adjustment methods, this is the user to focus on the purchase.
In addition, it is worth noting that "can continue to run 7x24 hours," although the LCD splicing screen manufacturers in the marketing of the key targets, but in practical applications, LCD splicing screen also need to properly rest, otherwise it will affect the life - Related studies have found that LCD splicing screens that work continuously for more than 96 hours at full load will accelerate their aging, and even burn out in severe cases. In practical applications, it is best for the user to allow the LCD splicing screen to be intermittently rested. If the conditions are not allowable, it is possible to try to change the display content of the screen at different time intervals so that the screen body can be adjusted slightly while waiting for a working state.
LCD splicing screen physical resolution is not adjustable, pay attention to the marketing trap
Due to the display effect, the resolution of the LCD splicing screen has always been the focus of attention of the industry users, and it is also an important consideration of the industry users when selecting products. Here to say 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 and cannot be adjusted. The higher the physical resolution, the higher the resolution of the large LCD screen.
Driven by the trend of high-definition, "the highest support for 1920x1080p resolution" has become a common propaganda approach for businesses, but it is worth emphasizing that this only represents the LCD display can support this signal input format of 1920 × 1080, the physical resolution of the panel The rate may not reach 1920×1080, but it may be 1366×768 (the minimum resolution limit of the national HD display standard). If the latter is the actual operation, only 1920×1080 signals can be converted into 1366×768 format according to the panel output through the image change and then presented to the audience. In the process, there will be compression and loss of the screen display effect. Industry users must pay more attention to the actual purchase.
Visual angle and wide viewing angle are two things
In the daily marketing of LCD splicing screen, wide viewing angle is undoubtedly a common object. Generally speaking, "wide-angle" in the marketing of a business means the viewing angle of a liquid crystal splicing screen, that is, the user can clearly observe the angle of all the contents on the screen from different directions. The wide viewing angle refers to the degree to which the color cast of the liquid crystal splicing screen is. At present, because the measurement standard is not uniform, the results obtained are not the same, and not a specific numerical value. At present, the viewing angle of the LCD splicing screen is 178 degrees or more, which can be regarded as achieving an absolute viewing angle effect.
Angular contact ball bearings mainly bear large unidirectional axial load. The greater the contact angle, the greater the load bearing capacity. The material of cage is steel plate, brass or engineering plastics. The forming method is stamping or turning. It is selected according to the bearing form or using condition. Others include combined angular contact ball bearings, double row angular contact ball bearings and four-point contact ball bearings.
Angular contact bearings are able to support radial load and axial load. As single row angular contact ball bearings can only support axial load in single direction, matched bearing mounting is often adopted to them as matched parts of bearings, preload for them is more convenient. Retainers are made of brass, synthetic resins or others subject according to individual bearing features and application conditions.
