Problems solved by technology

[0004] However, it is quite troublesome to always turn on or turn off the light to adjust the brightness ratio of the image and the environment. Therefore, some users do not turn on the light at all, so that the environment brightness becomes very low, and the image brightness and the environment brightness are relatively bright. The dark contrast is stronger, so when users or viewers watch the images projected by the projector, their eyes feel tired and they want to doze off. Moreover, the projector is no longer a must-have product in the office, and gradually more and more There is a projector in the family, if the projector is used in an environment with strong contrast between light and dark for a long time, it will not only cause damage to the user's eyes, but also make the user feel exhausted when using the projector, which will affect the user's elegance

Embodiment Construction

[0059] In order to enable the examiner to have a further understanding and understanding of the structural features and the achieved effects of the present invention, a preferred embodiment and a detailed description are provided, as follows:

[0060] see figure 1 , which is a schematic structural diagram of a projector in an embodiment of the present invention; as shown in the figure, the display device for displaying a frame of the present invention is applied to a projector 10, which includes at least one light source 12, at least one dichroic mirror 13, At least one liquid crystal display device 14, a light-combining prism 15 and a lens 16; the dichroic mirror 13 is used to receive the light emitted by the light source 12, and make a part of the light pass through the dichroic mirror 13, and the other part of the light is reflected in the dichroic mirror 13. Dichroic mirror 13; and liquid crystal display device 14 is used for receiving the reflected light of dichromatic mi...

Abstract

To apply in a projector with LCD, it lets the LEC rim form an inclined surface, or sets a shield body on the first or second glass substrate of LCD; to a projector with a digital micro reflector element, it forms a lens on the lens edge, or applies a control unit, or forms an inclined surface on lens edge; to a display, it sets a light source behind the display and puts the display in front of a wall to let the source irradiate the wall plane and form a layer with climactic light to release the contrast.

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 su...
