Description

Backlight rotary screen Technical Field The utility model relates to the technical field of display equipment, in particular to a backlight rotary screen. Background In the technical field of modern display, a backlight rotary screen is used as equipment with a display function and adjustable visual angle characteristics, and is widely applied to various scenes such as commercial display, advertising, information release and the like. However, the conventional backlight rotating screen has a plurality of problems to be solved in the actual use process, and the problems mainly include: (1) The internal structure of the traditional backlight rotary screen is usually closed, and when key components such as a lamp panel, a light guide plate and the like in the screen are required to be overhauled, replaced or upgraded, professional technicians are often required to resort to complex tools, a great deal of time and effort are consumed to open the screen shell, and the internal structure is contacted, so that the maintenance cost is definitely increased, and the maintainability of equipment is reduced; (2) Most backlight rotating screens adopt traditional fixed power interfaces, so that the installation position of equipment is limited, the equipment is required to be close to a specific power socket, interface specification matching needs to be ensured when an external power supply is connected, and once the interfaces are incompatible, an additional converter is required, so that the use inconvenience is increased; (3) The existing backlight rotating screen is single in design and lacks innovation and change. Most of the front opening edge areas of the screen are of simple plane structures, so that the requirements of users on diversification and individuation of the appearance of the screen cannot be met, the front opening edge areas are difficult to stand out from a plurality of display devices, and the attention of the users is attracted.
