Problems solved by technology

[0006] The current liquid crystal lens grating can only form lenses in one direction, and the corresponding stereoscopic display device can only form a stereoscopic display effect in one direction. When the display device is rotated, the viewer will not be able to obtain a good stereoscopic visual experience. This greatly limits the application of stereoscopic display and reduces the stereoscopic viewing experience of the viewer

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] see figure 1 , is a structural schematic diagram of a specific embodiment of the stereoscopic display device of the present invention. The stereoscopic display device 100 provides parallax display images to a specific direction in space, and includes a light guide panel 1 and a display panel 2 .

[0027] The display panel 2 is used for displaying stereoscopic parallax images, and generally includes pixel units arranged in a matrix. The display panel 2 may be a liquid crystal display panel, a plasma display panel, an organic light emitting display panel, etc., and is not limited here. In this embodiment, a liquid crystal display panel is used for illustration.

[0028] The light guide panel 1 is arranged on the display surface of the display panel 2 to guide the displayed parallax image light emitted by the display panel 2 to a predetermined ...

Abstract

The invention relates to a three-dimensional display device, which comprises a display panel and a light ray guide panel, wherein the light ray guide panel is arranged on the display surface of the display panel; the light ray guide panel is used for guiding parallactic image light rays displayed by the display panel to a predetermined visual field spatial position to realize three-dimensional display; the light ray guide panel is an electrically-controllable lens grating which forms a plurality of lens gratings in different extending directions under electric control; and the distances between the plurality of formed lens gratings and the display panel are consistent. The three-dimensional display device has the advantages of capability of forming three-dimensional display pictures in multiple directions and consistent watching distance.

Description

technical field [0001] The invention relates to the fields of liquid crystal lens gratings and stereoscopic displays, in particular to a liquid crystal lens grating in which lens gratings are formed in multiple directions and a stereoscopic display device using the liquid crystal lens gratings. Background technique [0002] There is a distance between the left eye and the right eye of a person, resulting in a slight difference in the viewing angle of the two eyes. Such a difference will cause a slight parallax in the scenes observed by the left eye and the right eye respectively, thus forming a stereoscopic image in the human brain. [0003] When viewing a general stereoscopic display device, it is necessary to wear stereoscopic glasses, so that the viewer who originally wears glasses (such as myopia glasses, presbyopic glasses, etc.), in order to obtain a clear viewing effect, needs to overlap two pairs of glasses to make the stereoscopic display It is inconvenient to watch...
