Multi-surface display device

Abstract

The invention discloses a multi-surface display device, comprising a multi-surface display structure formed by at least two display panels, and a light source, wherein the light source is arranged at the bottom of the middle position of the multi-surface display structure, the top of the multi-surface display structure is also provided with a reflection curved surface, and the reflection curved surface is formed by at least two reflection sheets with dip angles. Through arranging the light source at the bottom of the multi-surface display structure and reasonably utilizing the bottom space of the display device, lamp shadow can be eliminated, and the image quality can be improved. Light emitted by the light source can be reflected by the reflection curved surface on the top of the multi-surface display structure, so that emergent light of the display panels is uniform, light energy can also be fully utilized, the utilization rate of the light source is improved, and the goal of energy saving is achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a multi-face display device. Background technique [0002] At present, in most public places, display devices are often used to provide information to passing audiences. However, in order to allow audiences from all directions to watch the display screen, single-sided display devices can no longer meet the demand, so multi-sided display devices are needed. [0003] A common way to realize a multi-faceted display device is to use multiple independent display structures to splice multiple backlight sources in the form of light sources for multiple display structures, or to add multiple backlight sources between the display structures. However, each display device and backlight need to be set separately, and because there are differences between different backlight sources, there will also be color differences between each display device during the display process, which will affec...

[0002] At present, in most public places, display devices are often used to provide information to passing audiences. However, in order to allow audiences from all directions to watch the display screen, single-sided display devices can no longer meet the demand, so multi-sided display devices are needed.

[0003] A common way to realize a multi-faceted display device is to use multiple independent display structures to splice multiple backlight sources in the form of light sources for multiple display structures, or to add multiple backlight sources between the display structures. However, each display device and backlight need to be set separately, and because there are differences between different backlight sources, there will also be color differences between each display device during the display process, which will affect the viewing experience of the viewer. viewing experience

In addition, the cost of splicing multiple backlight sources is also high. Adding a light source between multiple display structures, the light source is placed directly behind the display panel, resulting in light shadows, which are difficult to eliminate and affect the uniformity of the picture.

[0004] To sum up, the multi-faceted display devices in the prior art have light shadows during display, which affects the display quality of the picture
