Video wall is a complete LCD video wall display unit, can be used as a display alone, but also can be spliced with liquid crystal into a large screen use. According to different use requirements, different functions can be achieved: single screen display, single screen alone display, any combination of display, large screen LCD display, etc..
Video wall is a complete finished product, that is, hanging that use, installation is as simple as building blocks, single or multiple LCD video wall use and installation are very simple. Now many areas are used in the video wall, the display effect is very good, the market also has a lot of video wall brands, such as: LG, Samsung, etc.. Because of its unique advantages, video wall market share is growing, so what are the advantages of video wall?
1.Personalized design, and installation environment harmonization
Insufficient maintenance space; complex and variable shape; different installation methods, consistent with the image of the shopping center, mostly chain stores, remote control and operation can be achieved; viewing distance, high brightness required, large screen area.
2.Good display effect
Shenzhen CY Digital Signage LCD video wall is the most important is the size of the spacing and brightness. Because of its direct impact on the display effect of the LCD video wall large screen. Currently on the market in terms of LCD video wall, LCD video wall product resolution up to 1920*1080P, 700cd/m2 high brightness, 3000:1 high contrast ratio, 178 degrees wide viewing angle, very high color saturation display image color beautiful, better reproduction, more prominent sense of hierarchy, high quality display effect is unmatched by other displays.
3.Long service life
Compared with DLP and PDP screen, LCD video wall life is much longer, and its power is lower, in the work of heat is also very little, the chance of failure when working is also much lower. PDP screen in the plasma easy to produce plasma branding, although its dynamic display life will be up to tens of thousands of hours or more, but if the screen in the high brightness display state, then The DLP screen lamp life is both 3000-5000 hours.
As the purchase of the LCD video wall is a precision product, is an electronic product, so we can not ensure that the process of use does not have any problems, when buying the best choice of manufacturers with after-sales capabilities, otherwise, if the purchase of the LCD video wall problems then it is difficult to get the best protection. That the most important point after the purchase is how to maintain and clean it?
1.Try to avoid ultra-long time running LCD video wall wall
LCD video wall due to long working hours can easily make some pixel overheating, once more than the limit will lead to permanent damage, which is often said to form a "bad point". Because the LCD video wall pixel point is composed of liquid crystal body, so when the continuous full load work for more than 96 hours, it will accelerate its aging, and in serious cases, even burned. Therefore, if we must work for a long time, it is best to intermittently let it rest for a while, or often at different intervals to change the screen to show the content, because in the wait for the work state to reduce the brightness, or its operation in the screen protection mode for a while, this simple practice can not only delay the aging of the LCD, but also to avoid damage to the hardware.
2.Avoid strong impact and pressure
video wall is very fragile and delicate, impact resistance is not too strong. This is because the LCD contains many precision glass components and agile and delicate electrical components, once a strong impact will lead to DID video wall and other related components damage. So be sure to avoid the shock of a strong impact. At the same time, also pay attention to do not apply pressure to the surface of the LCD screen, such as pointing fingers to a part of the screen, which can easily cause bad points to increase the move.
3.Try to avoid self-assembly
LCD video wall no matter what the problem, are prohibited to self-assembly LCD video wall (especially for the general DIY interest is even more so), if the LCD video wall does not work, you can find CY Digital Signage to help solve. As the LCD background lighting components in the transformer in the shutdown after a certain period of time may still with 1000V high voltage (albeit micro-current), and non-professionals if not handled well may cause new failures of the components.
4.With the appropriate method, the appropriate cleaning agent
If the LCD video wall surface is found to have dirt, you should use the exact method to remove the dirt. The best medium to use is soft, non-fiber material, such as skim cotton, lens paper or soft cloth, etc., and then dip a little glass cleaner to gently wipe it away, prohibit the use of alcohol-based chemical solutions, and can not use rough cloth or paper items, because such substances are easy to produce scratches. Special reminder, do not spray the cleaner directly to the surface of the screen, it is easy to flow to the screen inside the video wall caused by a short-circuit fault inside, causing unnecessary losses.
5.Pay attention to the maintenance of environmental elements
The surrounding environment on the video wall will have a direct impact. video wall large screen use role and longevity if the light is too bright, and even direct light, on the one hand, affect the visual communication of the advertising machine, on the other hand, direct light will damage the screen electronic components. In addition, video wall large screen is located in the environment air humidity to suit, electronic equipment is too wet will only affect the circuit condition and cause problems. Indoor temperature is recommended between 25 degrees 26 degrees, you can install air conditioning indoors to fully ensure the use of LCD video wall temperature. When the temperature is very low, will affect the normal use of the outdoor screen, generally below -30 degrees Celsius, it is recommended to temporarily stop using. Of course, take other measures such as the installation of air conditioning in the box, can also ensure normal use.
