China Education Equipment Purchasing Network News: The large screen splicing market has always been the world of DLP rear projection splicing, but since the LCD splicing came, it has brought a great impact on the entire splicing market. Not only the number of enterprises engaged in the LCD splicing industry has grown rapidly, but LCD splicing products are also in the monitoring centers of teaching, government agencies, power, water conservancy, telecommunications, public security, military, armed police, railway, transportation, mining, energy, steel, enterprises, Dispatch centers, command centers, conference rooms, exhibition halls and other places are widely used. What are the advantages of LCD splicing screens? Why are they widely favored by users? The following is for you to answer one by one.
First of all, compared with the traditional DLP rear projection splicing, the size of the liquid crystal splicing is very thin and light. Whether it is used in special occasions such as airport waiting halls and subway passages, its value is self-evident. Because of this, not only can the daily rent of ten yuan or more per square meter be saved, but also a beautiful special effect. The ultra-thin allows the LCD splicing to be as consistent as possible with the wall design of the space, rather than a large bulge, which is an aesthetic advantage that is sufficient to overcome DLP splicing. It is precisely because of its ultra-thinness that the LCD splicing has become very flexible. Users can arbitrarily turn it upside down, rotate it, and tilt and place it at any horizontal and vertical angles. Its diverse splicing methods are widely favored. Not only are users more keen on alien splicing, but even manufacturers have begun to invest more energy in doing so. Second, LCD splicing has the characteristics of long life and relatively low maintenance cost. Liquid crystal display technology is one of the most excellent flat panel display technologies at present. The lamp tube of the liquid crystal unit used in the splicing wall has a service life of more than 60,000 hours and the image is stable without any change after long-term work. The liquid crystal display technology does not have any consumable equipment that needs to be replaced regularly, so maintenance and repair costs are extremely low. More importantly, compared with traditional DLP splicing, another huge advantage of liquid crystal display technology is the high efficiency of light source utilization. This also determines that the liquid crystal display unit is easier to achieve higher display brightness. At present, high-brightness LCD is no longer a new technology, and several domestic and international companies have launched it. These display products can not only fill the demand for liquid crystal display applications in some special fields, but also open up the possibility of liquid crystal display applications in outdoor and direct sunlight.
General knowledge of LCD splicing screen maintenance: It is precisely because of these many advantages that the development speed of LCD splicing in the market is unmatched, including the number of enterprises and the number of users have grown rapidly. But as more and more users of LCD splicing systems, more and more problems are found. What should I pay attention to during the normal use of the LCD splicing system? How can the service life of the system be higher? Do n’t worry, let ’s take a look at the LCD splicing screen. It is easy to overheat some pixels because of long-term work. Once the limit is exceeded, it will cause permanent damage, which forms a commonly-called dead point. Since the pixels of the LCD splicing screen are composed of liquid crystals, when working continuously at full load for more than 96 hours, they will accelerate to aging, and even burn out in severe cases. Therefore, if the user must work for a long time, it is best to let them take a break intermittently, or often change the content of the screen display at different intervals, because it is necessary to reduce the brightness when waiting for work, or it is in the screen saver mode The next operation will not only delay the aging of the LCD screen, but also avoid hardware damage. In addition, no matter what problems occur in the LCD, it is forbidden to assemble the LCD splicing screen by yourself (especially for those who are interested in general DIY). If the LCD splicing screen is not working properly, you can seek help from the manufacturer. Because the transformer in the LCD background lighting component may still carry a high voltage of 1000V (although it is a small current) after a certain period of shutdown, non-professionals may cause new failures of the component if it is not handled properly. Moreover, the LCD screen is very fragile and expensive, and its impact resistance is poor. This is because the LCD contains a lot of precision glass components and agile electrical components. Once a strong impact will cause damage to the LCD screen and other related components. Therefore, we must avoid the shock of strong shocks. At the same time, we must pay attention not to put pressure on the surface of the LCD screen, such as pointing a certain part of the screen with your finger, which can easily cause the increase of dead pixels.
In addition, if any dirt is found on the surface of the LCD splicing screen, the dirt should be removed using an accurate method. The medium used is preferably a soft, non-fibrous material, such as absorbent cotton, lens paper, or a soft cloth, etc., and then gently wipe it off with a little glass cleaner. It is forbidden to use chemical solutions such as alcohol or rough. Cloth or paper items, because such substances are prone to scratches. We should remind everyone here that do not spray the cleaning agent directly onto the surface of the display screen, it will easily flow into the screen and cause a short-circuit failure inside the LCD screen, causing unnecessary losses.
Common problems and solutions of LCD splicing screen flower screen Finally, the author will teach you a few tricks, a few small methods to deal with LCD splicing screen flower screen, I hope you can help. ; Common symptom 1: The clutter phenomenon will appear on the LCD screen.
Solution: The above situation is likely to be due to the loose connection between the LCD splicing screen and the graphics card. As long as the connection cable is firmly connected, the situation of clutter and noise can be improved.
Common symptom 2: Irregular and intermittent horizontal stripes appear on the screen
Solution: Check whether the graphics card is overclocked. If the graphics card is overclocked, the above situation often occurs. At this time, the overclocking amplitude should be appropriately reduced, but it should be noted that the frequency of the video memory must be reduced first.
Common symptom 3: If the flower screen appears, but the above two tricks fail to take effect
Solution: After the above situation occurs, the user must check the quality of the graphics card. The user can check whether the anti-electromagnetic interference and electromagnetic shielding quality of the graphics card pass. The specific method is: install some components that may produce electromagnetic interference as far away as possible from the graphics card (such as a hard disk), and then see if the flower screen disappears. If it is determined that the electromagnetic shielding function of the graphics card is not enough, you should replace the graphics card, or make your own shield.
There is another way to solve the problem of screen splatter, that is, check whether an incompatible graphics card driver is installed. This situation is generally easy to be ignored, because the update speed of the graphics card driver is getting faster and faster, and some users can't wait to install the latest version of the driver. In fact, some of the latest drivers are either a beta version or a version optimized for a specific graphics card or game. The use of such drivers may sometimes lead to the appearance of flower screens.
