The large-screen splicing plan refers to the planning and design of the previous project, such as how many screens are needed for splicing, how to display the content and signals on the screen, how to distribute signals in the background, and how to concentrate signals between multiple remote locations on a large screen On display etc. So how is this scheme designed?
First, choose which stitching technology to use
The stitching technology used for different display needs is not the same. Currently the mainstream stitching technologies include three types: LCD LCD splicing, LED splicing, and DLP splicing.
They are different in terms of technical composition and display effect. For example, LCD splicing screens are mainly used in security monitoring, conferences, exhibition halls and other occasions. This is because its panel is stable and supports 24-hour continuous startup, and its resolution is high, so its The image displayed on the screen is clearer and suitable for close viewing. The display effect is similar to that of a TV, except that the screen is larger, the bezel is narrower, and the panel is more durable.
The led splicing large screen solution is mainly used in advertising, exhibitions, such as conferences, lecture halls, outdoor advertising screens, and so on. This is because LED is waterproof and can be used outdoors. In addition, because its screen has no seams, it is more suitable for displaying the entire screen image, but because of its lower resolution, it can only be used for some long-distance viewing. occasion. In addition, due to its high brightness, it is not suitable for long-term viewing, and will be more dazzling.
DLP is a light source refraction display technology. It is mainly used in monitoring and conference displays like LCDs. However, due to its higher price and general cost performance, fewer and fewer people are used. Compared with the largest LCD splicing, The advantage is that the patchwork is small, only about 0.2mm, and it is mostly used in television stations and command centers.
How many signal sources are on the screen
No matter which type of large-screen splicing solution involves the function of the screen on the signal source, the general signal source is a monitoring signal or a computer signal. At this time, it should be determined in advance based on the number of surveillance videos and the number of hard disk video recorders, or the number of computer inputs How many large screens to use. For example, there are 45 video monitors in total. If 9-segment display is used, 6 large screens are required to meet the requirements. If a single-screen 4-segment display is used, 12 screens are required.
In addition, when there are many computer signals, a related matrix needs to be provided according to the number to realize functions such as switching of each signal.
Third, how many pieces of large screen design
The core of the large-screen splicing solution is the display screen. The most important thing here is the number of screens. This is not only related to the budget range, but also to the number of signals and the size of the installation location. Screen, and plan ahead for ground clearance height and maintenance space.
At present, the mainstream LCD splicing screen sizes are 46, 49, 55, 65 inches, etc. The panels are mainly used by Samsung and LG. Such as 3.5mm, 1.8mm, 0.88mm, etc., even using 0mm seamless splicing screen.
Fourth, the installation method
The current mainstream installation methods include wall mounting, brackets, cabinets, etc. This should be designed according to the actual installation environment. If the number of large splicing screens is small and the background wall can bear the load, it can be directly wall-mounted, and if it cannot bear the load, the number is There are many ways to install floor stand or cabinet.
In addition, if the installation location is too small and there is no post-maintenance space, it can also be designed as a pre-maintenance method. In short, the entire splicing large screen solution involves what kind of splicing technology is used, the number of splicing, and how the signal source is displayed on the screen. The problem, and then the specific details of the plan, may be slightly different on each occasion, and personalized design is also required.
