Abstract

The invention provides a low-crosstalk liquid crystal lens 2D-3D switching device, belongs to the technical field of optical 3D display, and aims at solving the problems that an existing 2D-3D switching technique is obvious in 3D crosstalk and low in comfort degree. According to the low-crosstalk liquid crystal lens 2D-3D switching device, the inner surface of an upper glass substrate and the inner surface of a lower glass substrate are provided with an upper ITO electrode and a lower ITO electrode respectively, and a liquid crystal layer is filled between the two electrodes; the liquid crystal layer is in a parallel distribution mode when the device is powered off; a whole-plate electrode is adopted as the upper ITO electrode; a segmented electrode is adopted as the lower ITO electrode, and the lower ITO electrode is uniformly etched into n conductive electrodes in an equivalent period, wherein n is an odd number; voltages loaded on the n conductive electrodes are in a mirror symmetry mode and are asymptotically increased from the centers to the two ends; the on-load voltage of the conductive electrode located in the center is 0, the on-load voltages of the conductive electrodes located at the left end and the right end are + / -m V, and the on-load voltages of the conductive electrodes located at any other positions are + / -m(1-y / h). A gradual electric field is applied, and a liquid crystal layer equivalent lens is formed.

Description

technical field [0001] The invention belongs to the technical field of optical 3D display. Background technique [0002] Naked-eye 3D, that is, you can enjoy the three-dimensional images in a wonderland without wearing any auxiliary devices, and it is becoming more and more popular in the market. Naked-eye 3D technology is mainly divided into slit technology and lenticular grating technology. When the slit technology is used, the 3D state The light transmittance emitted by the display screen is low, which is generally related to the number of viewpoint images used. For example, the number of viewpoint images used is n, and the light transmittance in 3D state is 1 / n. The use of display screens is restricted because the number of viewpoints generally used exceeds 5 for display screens of 15 inches and above. And the biggest advantage of the lenticular lens technology is that it uses the principle of light refraction, so the brightness of the display is basically not affected....
