Description

Technical Field

[0001] The utility model relates to the technical field of large conference screens, in particular to a large conference screen with an improved structure. Background Art

[0002] With the advent of the information age, the rapid development of computer multimedia technology, the widespread application of network technology, from the establishment of command and monitoring centers and network management centers to temporary meetings and technical lectures, the large-screen projector technology that has developed rapidly in recent years is extremely mature, the scope of application has been further expanded, and the market has become increasingly active due to the growth of demand. However, in actual use, large conference screens with similar structures still have many defects, such as: they do not have the function of automatic cleaning. When the large screen is placed, a large amount of dust will accumulate on the surface of the screen, affecting the cleanliness of the conference room and reducing the clarity of the screen. The large screen is extremely fragile and can be easily damaged when bumped, causing property losses. At the same time, it does not have the function of quickly replacing a single screen. Since the large screen is composed of small screens that are equidistant from each other, the operation steps are relatively cumbersome when replacing a single screen after it is damaged, which affects the speed at which the maintenance staff can complete their work. Therefore, it is necessary to design a large conference screen with an improved structure. Utility Model Content
