Problems solved by technology

Because there is periodic interference between the grating and the pixel array of the flat-panel display, the image produced by the pixel array 7 of the flat-panel display will form moiré in the displayed image 9 after passing through the grating 8. Obviously, this moiré phenomenon has great influence on the three-dimensional The effect of the picture has a great influence, which will destroy the appreciation of t

Embodiment Construction

[0051] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0052] The invention provides a stereoscopic display device, which includes a display panel and a liquid crystal lens. The display panel is used to display the left-eye image and the right-eye image with parallax; the liquid crystal lens is arranged on the display panel, and guides the left-eye image and the right-eye image with parallax to the corresponding left eye and right eye of the viewer respectively.

[0053] see Figure 5 , for the convenience of describing the present invention, Figure 5 Only the structural schematic diagram of the liquid crystal lens is shown. Such as Figure 5 As shown, the liquid crystal lens 200 includes a first substrate 210 , a second substrate 220 , a liquid crystal layer 230 , a first electrode layer 240 , a second electrode layer 250 , a first alignment film 260 and a second alignment film 270 .

Abstract

The invention discloses a stereo display device and a liquid crystal lens thereof. The liquid crystal lens comprises a first substrate, a second substrate, a liquid crystal layer, a first electrode layer and a second electrode layer, wherein the first substrate and the second substrate are arranged at a certain interval; the liquid crystal layer is arranged between the first substrate and the second substrate; the first electrode layer is arranged between the first substrate and the liquid crystal layer; and the second electrode layer is arranged between the second substrate and the liquid crystal layer; the first electrode layer and the second electrode layer are used for producing electric fields, so that the liquid crystal layer can produce a lens effect; and the first electrode layer comprises a plurality of strip electrodes, the strip electrodes are arranged at a certain interval, and each strip electrode is provided with a structure with gradually-changed transmittance along a direction perpendicular to the extending direction of the strip electrode. Through the mode above, by using the stereo display device and liquid crystal lens disclosed by the invention, the imaging quality can be improved, and a good image display effect can be achieved.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a stereoscopic display device and a liquid crystal lens thereof. Background technique [0002] With the rapid development of stereoscopic display technology, there are more and more demands for stereoscopic display equipment. Among the many technologies for realizing 3D stereoscopic display, naked-eye stereoscopic display has the advantage of not requiring the observer to wear special glasses. favored among. [0003] At present, the main way to realize naked-eye stereoscopic display technology is to divide the pixel units of the display panel into odd-numbered columns of pixels and even-numbered columns of pixels in the horizontal direction by setting gratings in front of the display panel, thereby providing two images for the left and right eyes of the viewer. Different images use the parallax effect of the viewer's left-eye image and right-eye image to form a depth of field, ...
