Description

Technical Field

[0001] The utility model belongs to the technical field of display cabinets, and in particular relates to a multi-angle unidirectional lighting and transparent display device. Background Art

[0002] Display devices are mostly used for the display of high-end products such as jewelry and watches, as well as artworks and cultural relics, and lighting is used to better show the bright appearance of the exhibits, so that consumers can see the details more easily. The lighting of existing display devices is mostly spotlights, which is a point light source, and the display effect is not perfect. If a surface light source is used, one side of the light source is blocked and cannot be fully displayed 360°. When the display device is surrounded by transparent windows on all four sides, the scene outside the display device will also affect the shooting effect of the exhibits (that is, the opposite environment will be photographed, including some environmental reflections). The transparent LCD screen used in some existing display devices can display some exhibit information in addition to the actual exhibits, but the transmittance of the transparent LCD screen is low, usually less than 20%, so it is necessary to add a high-brightness light source in the display device, so that the light source consumes a lot of power. Some exhibits are placed in the slots of the wall, and a display surface is installed at the slot. The display surface is generally single-sided display (other embedded surfaces are mostly used as light source reflectors, which are not transparent and do not display), and the display effect is not ideal;

[0003] In view of the above shortcomings, the utility model designs a lighting display device with a simple structure and low cost and a multi-angle surface light source, which can also be matched with transparent LCD or OLED display screens to achieve multi-sided transparent display without any interference between the screens.
