Problems solved by technology

However, the change of the refractive index of the known liquid crystal lens is not smooth enough, so that the lens effect is not as good as that of the solid lens
In addition, the strip electrodes of the known liquid crystal lens are arranged in the vertical direction, so the lens effect can only be provided in the horizontal direction, and there is no lens effect in the vertical direction, so the application and effect of the three-dimensional display device are limited.

Embodiment Construction

[0028] Please refer to figure 1 . figure 1 It shows a schematic diagram of the liquid crystal lens of the first preferred embodiment of the present invention. Such as figure 1 As shown, the liquid crystal lens 1 of this embodiment includes a first transparent substrate 11, a second transparent substrate 12, a first transparent electrode 21, a second transparent electrode 22, a liquid crystal layer LC, and a first alignment film 31 , A second alignment film 32, and a first electric field leveling layer 41. The first transparent substrate 11 may be, for example, a rectangular substrate, which has sides 11A, 11B, wherein the side 11A and the side 11B are adjacent sides. The first transparent substrate 11 and the second transparent substrate 12 may include, for example, a glass substrate, a quartz substrate, or a plastic substrate, but are not limited to this and may also be other various types of transparent substrates. The second transparent substrate 12 and the first transparen...

Abstract

The invention discloses a liquid crystal lens. The liquid crystal lens comprises a first transparent substrate, a second transparent substrate, a first transparent electrode, a second transparent electrode, a liquid crystal layer, a first orientation film, a second orientation film and a first electric field homogenization layer. The first transparent electrode comprises a plurality of first strip-shaped electrodes, the first strip-shaped electrodes are arranged in the first direction and are parallel to each other, and the first direction is neither parallel nor perpendicular to the side edge of the first transparent substrate. The first electric field homogenization layer is arranged between the first orientation film and the first transparent electrode or between the second orientation film and the second transparent electrode.

Description

Technical field [0001] The invention relates to a display device capable of switching between a two-dimensional display mode and a three-dimensional display mode and a liquid crystal lens thereof, in particular to a switchable two-dimensional display mode and a three-dimensional display having an electric field equalizing layer that can smooth the change of refractive index Mode display device and its liquid crystal lens. Background technique [0002] With the continuous improvement of related technologies of display devices in recent years, the development and application of stereoscopic display devices have become more and more vigorous. The main principle of the stereoscopic display device is to make the viewer’s left eye and right eye receive different images, and the images received by the left eye and right eye will be analyzed and overlapped by the brain to make the viewer perceive the layering of the image. And depth, and then create a three-dimensional effect. [0003] G...
