Description

Technical Field

[0001] The utility model relates to an adjustable display device for a billboard. Background Art

[0002] When billboards are exhibited, display equipment is required. However, most existing display equipment can only adapt to billboards of specific sizes. When billboards of other sizes need to be replaced for exhibition, it is particularly inconvenient and has certain limitations. In addition, when existing billboards are exhibited using display equipment, their tilt angles are mostly fixed. Due to the different sizes of advertisements, in order to ensure the exhibition effect, the tilt angles often need to be adjusted adaptively according to their sizes. Most existing display equipment does not have the above functions, making it difficult to improve the exhibition effect of billboards.
