Stereoscopic display device and stereoscopic display method

Abstract

The invention discloses a stereoscopic display device which comprises a display unit and a liquid crystal lens unit, wherein the display unit is used for emitting image light outwards, and the liquid crystal lens unit is arranged above the display unit, receives the image light and is used for forming a first lens grating in the first half period of the image light and forming a second lens grating in the second half period of the image light. A half preset period is shifted between the formed first lens grating and the formed second lens grating, and the first lens grating and the second lens grating are used for separating the received image light into a left eye image and a right eye image, wherein the left eye image and the right eye image are alternated in the first half period and the second half period of a display area corresponding to the display unit. The stereoscopic display device is capable of performing full-resolution display and improving stereoscopic display effects, and is simple in structure and low in production cost. The invention further relates to a stereoscopic display method.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, and in particular, to a stereoscopic display device and a stereoscopic display method. Background technique [0002] The working principle of naked-eye stereoscopic display technology is mainly to use grating devices to control the images received by the left eye and right eye of the viewer, and due to the visual characteristics of the human eye, when the left and right eyes view the same content but have different parallax respectively. When there are two images, the human eye will observe a three-dimensional image synthesized from the two images. [0003] In the related art, naked-eye stereoscopic display implementations generally include: parallax slit gratings, micro-cylindrical lens arrays (or called cylindrical lens arrays), and directional backlights. Aiming at the implementation of the above-mentioned micro-cylindrical lens array, a stereoscopic spectroscopic devic...

Problems solved by technology

However, for the implementation of the above-mentioned microcylindrical lens arrays, all of them use space division to display stereoscopic images, which will cause the problem of reduced display resolution, thereby affecting the effect of stereoscopic display.

[0004] Therefore, how to avoid the reduction of the resolution of the stereoscopic display when using the microcylindrical lens array to form the naked-eye stereoscopic display has become a technical problem to be solved urgently.
