Problems solved by technology

Therefore, some users do not turn on the lights at all, so that the ambient brightness becomes very low, and the contrast between the image brightness and the ambient brightness is relatively stronger. Therefore, when users or audiences watch the images projected by the projector ...

Abstract

The invention discloses a display device for showing frames. If the display device is applied to a projector provided with a liquid crystal display device, a bevel is formed on the edge of the liquidcrystal display device, or a shading body is arranged on a first or second glass base plate of the liquid crystal display device; If the display device is applied to a projector provided with a bit micro reflector element, the edge of the bit micro reflector element is provided with a prism, or a control unit is used for controlling the bit micro reflector element, or a shaking surface is formed on the edge of the eyeglass of a lens of the projector; if the display device is applied to a display, a light source is arranged behind the display, and the display is arranged in front of a wall surface so that the light source irradiates to the wall surface of the back of the display. In such a way, climactic light is produced around the projector and the image of the display, thereby relievingthe brightness contrast between the image of the display and the environment.

Description

technical field [0001] The present invention relates to a display device, in particular to a display device displaying a frame, which generates a gradient light around an image of a projector or a display to ease the contrast between the image and the brightness of the environment. Background technique [0002] With the development of digital technology, home audio-visual products are becoming more and more popular, such as monitors, projectors, etc., and they can be found everywhere in life. However, these technological products bring incomparable fun and convenience to life. It also brings us some small injuries that are easy to ignore. For example, when using a display, the contrast between the image brightness of the display and the ambient brightness is often ignored. When the contrast between the image brightness and the ambient brightness is strong, it is easy to make users or viewers feel uncomfortable, especially In European countries, due to the latitude, the sunl...
