Problems solved by technology

[0004] However, since these implementations are difficult to avoid the loss of resolution in the horizontal direction, when a small screen is displayed, the screen will be split to produce a split phenomenon, making the image unclear to the observer or the image display is not fine enough, thus affecting the three-dimensional Viewing Effect of Stereoscopic Image

Embodiment Construction

[0046] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. 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.

[0047] see figure 1 , for the convenience of describing the present invention, figure 1 Only the structural schematic diagram of the liquid crystal lens is shown. The liquid crystal lens 100 includes an upper substrate 110 , a lower substrate 120 , a liquid crystal layer 130 , a deflection electrode (not marked), a common electrode 150 and a plurality of spacers 160 .

[0048] Wherein, the upper substrate 110 and the lower substrate 120 are relatively...

Abstract

The invention discloses a liquid crystal lens and a driving method thereof. The liquid crystal lens comprises an upper substrate and a lower substrate which are arranged at interval, a liquid crystal layer located between the upper substrate and the lower substrate, deflecting electrodes located at one side of the upper substrate adjacent to the liquid crystal layer, a common electrode located at one side of the lower substrate adjacent to the liquid crystal layer, and a plurality of spacers which divide the liquid crystal layer into a plurality of liquid crystal chambers along a direction parallel to the upper substrate and the lower substrate; and by controlling the dynamic periodic change of voltage applied to the corresponding deflecting electrode on each liquid crystal chamber, the liquid crystal layer alternatively forms a left half liquid crystal lens and a right half liquid crystal lens within a period. The invention also provides a stereo display device with application of the liquid crystal lenses. In such a way, the stereo display device provided in the invention realizes excellent three-dimensional display effect.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a liquid crystal lens, a driving method thereof, and a stereoscopic display device using the liquid crystal lens. Background technique [0002] In recent years, due to the greatly enhanced computer CPU processing speed and related functions, the three-dimensional display technology with the characteristics of large information capacity has been developed rapidly. Among the many technologies for realizing 3D stereoscopic display, naked-eye stereoscopic display is favored in the field of 3D stereoscopic display due to the advantage that the observer does not need to wear special glasses. [0003] At present, the main ways to realize naked-eye stereoscopic display technology include black-and-white parallax barrier gratings and cylindrical physical lenses. The eyes provide two different images respectively, and the parallax effect of the viewer's eyes is used to produce a three-di...
