How to Choose the Specifications of the LED Screen in the Lecture Hall?
Determine which specification to use for the LED screen based on objective factors, including the following aspects.
1. Which pixel pitch
There are many kinds of pixel pitches for LED screens. The smaller the pixel pitch, the higher the screen resolution and the higher the resolution, but the price will also increase accordingly. At this time, you must choose a more suitable solution, that is, That is, the display requirement can be met without increasing the cost. This point is mainly based on the viewing distance between the users in the nearest row and the users in the farthest row, and you can roughly calculate how many LED screens you should use. But generally speaking, the pixel pitch of the LED screen in this kind of indoor lecture hall will be below P3, so as to ensure the overall display effect.
2. Make a large display size
The size of the display area depends on the length and height of the school’s academic lecture hall, and the viewing distance and a number of viewers. The larger the screen, the better the display effect. If it is a lecture hall with hundreds of people, the entire LED screen must be done Dozens of square meters or more will do.
3. Use modules or cabinets
The use of modules is to splice together the modules, and the box is larger, which is equivalent to the size of four modules. It is more convenient to install and splice, the flatness is better, and the appearance is more beautiful. Therefore, the cabinet is more high-end, but it will also increase the cost, which can be determined according to the actual situation and budget.
4. How to install
Under normal circumstances, the installation of the LED screen in the lecture hall is bracket type, and there are also embedded ones. The space behind the rostrum of this kind of lecture hall is relatively small, so most of them are used for front maintenance installation, which saves space and facilitates maintenance.
5. Control equipment
The LED screen is only responsible for display, and a control device is needed between it and the signal source, usually an image processor is used to switch signals and realize some display functions, including multi-screen simultaneous display, superimposed roaming, etc. Therefore, the design of the school’s academic lecture hall LED screen scheme needs to consider various factors. Objective factors and user needs directly determine the specifications of the LED screen, especially the selection of pixel pitch. Different products have different structures, so each the LED screens used in the lecture hall are all different, and this needs to be designed according to the specific situation.
