Abstract
The invention is suitable for the technical field of stereoscopic display and provides a liquid crystal lens. The liquid crystal lens comprises a first substrate and a second substrate which are oppositely arranged; a second electrode is arranged on one side, towards a liquid crystal layer, of the second substrate; a second alignment layer is arranged between the second electrode and the liquid crystal layer; when being switched to a display mode, the liquid crystal lens is subjected to discharge treatment; liquid crystal molecules in the liquid crystal layer are returned to initial states and are obliquely arranged according to preset pretilt angles under the initial states. The liquid crystal molecules are obliquely arranged according to the preset pretilt angles under the initial states and quickly deflect under the action of driving voltage or deflection voltage, so that the switching delay phenomenon occurring in the display mode switching process is avoided, and the viewing experience of the liquid crystal lens is improved. The embodiment of the invention further provides a stereoscopic display device which avoids the switching delay phenomenon occurring in the display mode switching process and improves the viewing experience of the liquid crystal lens.
Description
technical field [0001] The invention belongs to the technical field of stereoscopic display, and in particular relates to a liquid crystal lens and a stereoscopic display device including the liquid crystal lens. Background technique [0002] Humans perceive the depth of objects through the slight difference between what the right and left eyes see, and thus recognize stereoscopic images. This difference is called parallax. Stereoscopic display technology is to create the parallax of the left and right eyes of people through artificial means, and send two images with parallax to the left and right eyes respectively, so that the brain can observe the real three-dimensional objects after obtaining the different images seen by the left and right eyes. a feeling of. [0003] With the continuous deepening of people's understanding of liquid crystal materials, spectroscopic devices made of liquid crystal materials, such as liquid crystal lenses, have a wide range of applications,...
