Hardware-based controllers are electronic devices built for specific purpose. They usually are built on array of video processing chipsets and do not have an operating system. The advantage of using a hardware video wall controller is high performance and reliability. Disadvantages include high cost and the lack of flexibility.   The most simple example of video wall controller is single input multiple outputs scaler. It accepts one video input and splits the image into parts corresponding to displays in the video wall.   Most of professional video wall displays also have built-in controller (sometimes called an integrated video matrix processor or splitter). This matrix splitter allows to “stretch” the image from a single video input across all the displays within the whole video wall (typically arranged in a linear matrix, e.g., 2x2, 4x4, etc.). These types of displays typically have loop-through output (usually DVI) that allows installers to daisy-chain all displays and feed them with the same input. Typically setup is done via the remote control and the on-screen display. It is fairly simple method to build a video wall but it has some disadvantages. First of all, it is impossible to use full pixel resolution of the video wall because the resolution cannot be bigger than the resolution of the input signal. It is also not possible to display multiple inputs at the same time

Currently on the market types of liquid crystal products and different let the user pick dazzled now commercial display chief supplier emperor Aidi for everybody simple introduction of ordinary liquid crystal display LCD splicing screen and the market difference. With the splicing technology is mature, LCD splicing screen performance also in constantly tends to perfect low power, slim and stylish appearance, long service life, the LCD splicing screen product service life of up to 100000 hours, support 7x24 hours work uninterrupted; and in 1920 x 1080p Full HD, uniform screen brightness, bright color high-definition display effect for LCD splicing screen is widely used in government, stadiums, transportation, energy, finance, broadcasting, entertainment, health care, education and other multiple industries.     1. price difference: Regular LCD splicing screen and liquid crystal display in the price is there is a certain gap, professional splicing screen assembly with metal shell, new a + industrial LCD screen, professional monitoring motherboard drivers, so cost than the display to much higher, now on the market a lot of cheap LCD splicing screen, in fact, are converted display, basically can be said is a display for a shell, even it is possible to use the old screen.   2.the difference between driving programs: Shows that the motherboard is not the same, the splicing screen driver board mainly deal with the dynamic image better, the liquid crystal display the boot time is generally not more than 8 hours, the is civilian level display board, and LCD splicing screen to twenty four hours a day, 365 days of work burden, so must the professional monitoring motherboard to ensure higher brightness, contrast and sharpness of ultra high temperature resistant and, thereby reducing the use loss of screen. Ordinary display, if the use of a long time, its brightness and contrast will drop soon, affecting its service life. This is why most of the liquid crystal display in the project has just been completed, can normally display the image, but after a period of time will be the cause of some of the screen dark.   3.the difference between the visual angle: LCD splicing screen visual angle can reach 178 degrees, while the ordinary liquid crystal display in the direction of 178 degrees can only see a blank. This is a very important criterion for the identification of the LCD splicing screen and LCD display. There is both of the input signal is not the same, splicing screen is mainly the input video signal, in order to meet the requirements, so the screen splicing interface will than many rich display different front-end equipment interface, such as emperor Aidi LCD splicing screen products with BNC, VGA, RGB, HDMI, DVI, variety of interface, to meet the different signal input requirements, and display of VGA signal input, interface is mainly VGA, S-Video, etc., and can not meet the requirements of various monitoring equipment of the input signal.   4.the difference between the LCD screen: From the level of liquid crystal screen, using a liquid crystal display is civil display, and regular LCD splicing screen such as CITIC display is used as its products is high brightness industrial grade A + LCD screen and the backlight requirements is higher than the display, so that when the liquid crystal display on a display surface painting will send false, and can not reach the good effect of the image.

An LED video wall is an amazing digital display that outperforms many other available technologies (video projectors, LCD displays and basic LED light panels.) They are completely modular and scalable in size, which makes them just as suitable for small events as for massive display applications. An LED wall is extremely bright, so you can display your visual content anytime, anywhere, including outside in the sun. With incredibly deep, saturated colors, an LED video wall is as breathtakingly beautiful as it is bright. Most video displays are flat. LED video walls break that limitation with 100% flexibility – any size, any shape, any 3 dimensional shape you can dream up can be realized with our modular, flexible LED video panels. With a pixel pitch as low as 2mm, you can achieve almost unlimited resolution. An LED video wall will perform brilliantly no matter what kind of video source: HDMI, DVI, VGA, component and composite video signals are all supported. Because of their light weight, these LED video displays are extremely portable; i.e. you can put them anywhere, hung from the ceiling, on lighting trusses, mounted to vehicles, stage props, etc. We can setup a video wall at your event in a couple hours, no need to set aside days for your stage's video screen setup. This amazing digital display technology can truly revolutionize your event.
