The lecture hall is an important place to hold educational work conferences and report on educational achievements. At present, most conference rooms and academic lecture halls in schools use projectors as display media, but they face the problems of insufficient brightness and poor effects. LED video walls as lecture hall displays with their seamless splicing, relatively good display effect, and efficient image processing capabilities, are gradually replacing traditional projection equipment and are becoming more and more popular in the market.

Video Wall As Lecture Hall Display

The LED video wall is a flat panel display that uses an array of light-emitting diodes as pixels to display various information, such as text, graphics, images, animations, markets, videos, video signals, etc. One of the basic uses of LED displays is for conference rooms, academic lecture halls, and digital classrooms. In the school’s academic lecture hall, creating an LED screen display solution can effectively assist the entire meeting and presentation, and it is usually installed behind the rostrum of the main lecture hall. The LED screen in the lecture hall can display the content of the meeting and information such as text in real-time, and can also be used for remote video conferences. Due to the relatively large area of this kind of lecture hall and a large number of viewers, the small-sized screen cannot meet the display requirements. In addition, the traditional projector has average clarity and serious reflection, so now the LED display has become this large-scale mainstream display solution for lecture halls or auditorium conference rooms. Due to the size of the lecture hall, the number of participants, and the viewing distance, the specifications of the LED screens used are not fixed. Typically, the pixel pitch varies. Of course, in terms of display effect, the smaller the pixel pitch, the better the screen will be. The clearer it is, but the corresponding cost will also increase. At this time, it is better to choose a more suitable LED screen. Therefore, when designing the LED screen scheme of the lecture hall in the early stage, some objective factors should also be considered comprehensively and combined with these factors. Choose which LED display to use.

What Objective Factors Need to be Consider?

Before designing the LED screen scheme of the lecture hall, it is necessary to understand the objective situation of the school’s academic lecture hall, that is, the size of the space on site, the length and height of the installation location, whether the background wall is flat or curved, and which one to use Installation methods, etc. Understanding these objective conditions is mainly to calculate the number of modules or cabinets used when selecting an LED screen, what is the resolution of the entire LED screen, and which installation method is used. In addition, it is also necessary to consider the viewing distance between the users in the nearest row and the users in the farthest row in the entire lecture hall, so as to calculate the spacing of the LED screens that should be used, because we need to ensure that the users at the rear can clearly see the screen The content displayed on the screen, so the pixel pitch of the LED screen cannot be too large, and the size of the screen is also required.

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.

Final Words

The lecture hall is mainly used for a variety of purposes, including digital classroom, conferences, academic discussions, speeches, reports, news releases, multimedia teaching and training, movie watching and other activities. Angles provide effective functionality and spectacular visuals to the viewer. If you want to create the most memorable user experience in your academic lecture hall, consider investing in the highest quality monitors on the market.
