In auditoriums or conference academic lecture halls of some schools or government departments, a large-screen display screen is usually installed on the stage to play the content to be displayed in real time. For a large demonstration hall like an auditorium, due to the large space, the large number of viewers and the relatively long distance, the traditional projection display can no longer meet the requirements of users. LED video walls and LCD video walls have become commonly used smart display products, and have gradually become large-screen display solutions commonly used in some large-scale occasions.
According to the size of different auditoriums and the area of the stage, considering the viewing distance of users and other reasons, it is necessary to design a separate video wall display solution. Therefore, it is necessary to consider the influence of various factors, such as what size video wall technology to use in which case, how to install it, etc., all need to be designed according to the specific situation.
Choose the right video wall：
LED video wall:
The advantage of the LED video wall is that there is no splicing gap, and the integrity of the entire screen is better, which is especially suitable for displaying a large picture in full screen. In addition, its brightness is relatively high. In such a large auditorium, high brightness means that the screen is brighter, and it has an advantage in comparison with external light, so it will not reflect light. In addition, the LED video wall is very suitable for displaying text, because it is composed of lamp beads, and only a U disk is needed to make it display our preset text content.
So if our auditorium mainly displays an image in full screen, and the viewing distance is relatively far, the lighting is good, and some welcome words are often displayed at the same time, then it is more appropriate to use an LED video wall.
LCD video wall:
LCD video wall is a kind of LCD screen similar to TV, it has the feature of splicing. A large-size display screen is formed by splicing, which is characterized by high resolution and high-definition screen. Moreover, the stability of LCD technology is very good, it is more reliable for long-term use, and there are fewer after-sales problems. Furthermore, the LCD screen is not dazzling, which is more suitable for long-term viewing.
Therefore, if it is some medium-sized conference lecture hall or auditorium, the user is relatively close to the screen and needs to watch the screen for a long time, it is better to use an LCD video wall. In addition, it has fewer after-sales problems in the later period, so it reduces a lot of maintenance costs. However, there will be a physical seam when the LCD video wall is spliced, which will slightly affect the overall display. The split-screen function of the LCD video wall is powerful. If there are multiple computers in our auditorium that need split-screen display, the LCD video wall can freely distribute the signal display.
In order to improve the design effect, technical means such as screen splicing, split screen, multi-screen synchronization and joint screen interaction are often used for design. On the one hand, such screen display can provide customers with the ultimate visual experience, on the other hand, it can also improve the utilization rate of the screen, reduce the occupation of space resources, and reduce the cost of use.
Layout and installation:
According to the overall design of the auditorium, ensure that the installation position of the video wall enables the audience sitting at any angle to clearly see the screen content.
Consider audio effects:
In addition to visual effects, audio effects are also factors that cannot be ignored in the exhibition hall. It is necessary to choose the appropriate sound system and sound effects, combined with the video wall, to improve the auditory experience and participation of the audience, and to optimize the audio-visual experience of the auditorium.
To adjust the lighting:
The lighting environment in the auditorium will also affect the display effect of the video wall. It is necessary to adjust the lighting according to the display content and audience characteristics to achieve the best display effect and audience experience.
Confirm the video source and signal transmission:
Determine the input sources for the video wall, which may be multiple computers or other multimedia devices. To ensure the stability of signal transmission, you can use high-quality HDMI or optical fiber connection.
Test optimization:
Complete testing and adjustments must be carried out before official use. Check the video wall for image quality, brightness and color accuracy, and ensure signal transmission and system stability.
To sum up, when using a video wall in a large lecture hall or auditorium, it is necessary to choose a suitable video wall, and video wall controllers,comprehensive layout and installation, consider audio effects, make suggestions such as lighting adjustment and test optimization, in order to achieve the best display effect and economic benefits. At the same time, during the use and maintenance of the video wall, it is also necessary to strictly abide by the operating instructions and safety regulations to ensure the stability and safety of the video wall.
