Problems solved by technology

However, these solutions are still based on the stereoscopic display formed by the existing cylindrical lens grating, which can only realize full-screen switching of 2D (two-dimensional) / 3D (three-dimensional), that is, the observer cannot watch content information containing 2D and 3D at the same time

Abstract

The invention discloses a liquid crystal lens, a stereo display method and a stereo display device. The stereo display method is applied to the stereo display device comprising the liquid display lens. The liquid display lens comprises a plurality of parallel first electrodes, a plurality of second electrodes which are arranged in parallel and different from the first electrodes in terms of extending direction, and liquid crystals filled between the first electrodes and the second electrodes. The method comprises the steps that at least one set of voltage distributed in the shaped of V in the preset direction or at least one set of voltage distributed in the shape of reversed V in the preset direction is exerted between the first electrodes and the second electrodes covering a three-dimensional display area, and the voltage which is distributed in the shape of V or distributed in the shape of reversed V is wholly or partially larger than the threshold voltage of the liquid crystals. Threshold voltage which is smaller than that of the liquid crystals or voltage which is larger than the saturation voltage of the liquid crystals is exerted between the first electrodes and the second electrodes covering a two-dimensional display area. The stereo display device can achieve the three-dimensional display effect and the two-dimensional display effect in a blended mode.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a liquid crystal lens, a stereoscopic display method and a stereoscopic display device. Background technique [0002] With the development of technology, stereoscopic display technology has developed a variety of display modes to enable observers to produce stereoscopic vision. Stereoscopic vision is produced because people's left and right eyes receive images from different angles, and after being synthesized by the brain, they perceive the layering and depth of objects. Current stereoscopic display devices can be classified into passive stereoscopic display devices and autostereoscopic display devices. When using a passive stereoscopic display device, the user needs to wear auxiliary equipment such as glasses or a helmet, and autostereoscopic display is also called naked-eye stereoscopic display, that is, the observer can see stereoscopic images without any auxiliary equipm...
