Problems solved by technology

[0002] In a general three-dimensional display, the liquid crystal lens made of liquid crystal and electrodes usually causes disclination lines in the liquid crystal lens due to the arrangement of the liquid crystal after voltage is applied, that is, the liquid crystal lens There is an obvious discontinuity in the refractive index
In this way, not only will the aberrations formed by the lens not meet the actual requirements, but also serious crosstalk will occur when the stereoscopic display displays images, resulting in poor image display quality.

Embodiment Construction

[0030] figure 1 A schematic diagram of a stereoscopic display according to an embodiment of the present invention is shown. The stereoscopic display 100 includes a backlight module 102 , a liquid crystal display panel 104 and a liquid crystal lens 110 , wherein the liquid crystal display panel 104 is disposed between the liquid crystal lens 110 and the backlight module 102 . When the liquid crystal lens 110 is in operation, the refraction angle of the light passing through the liquid crystal lens 110 will change due to the voltage applied to the liquid crystal lens 110 . In this way, when the light transmitted from the backlight module 102 and the liquid crystal display panel 104 passes through the liquid crystal lens 110, the viewer can produce aberrations due to the change of the light path by the liquid crystal lens 110, and then visually display a three-dimensional image. .

Abstract

The invention discloses a liquid crystal lens which comprises a first base plate, a second base plate and a liquid crystal layer; wherein the first base plate comprises a first electrode layer, a second electrode layer and an alignment layer; the first electrode layer is provided with a plurality of first electrodes; the second electrode layer is provided with a plurality of second electrodes; wherein the second electrodes are overlapped in a disalignment and one to one way with the first electrodes; one of the second electrodes deviates to the first electrodes corresponding to a first direction. The alignment layer is formed on the second electrode layer and has a first friction direction which is opposite to the first direction. The liquid crystal layer is arranged between the first base plate and the second base plate. The invention also discloses a three-dimensional display.

Description

technical field [0001] The present invention relates to a liquid crystal lens, and in particular to a liquid crystal lens applied to a three-dimensional display. Background technique [0002] In a general three-dimensional display, the liquid crystal lens made of liquid crystal and electrodes usually causes disclination lines in the liquid crystal lens due to the arrangement of the liquid crystal after voltage is applied, that is, the liquid crystal lens There is an obvious discontinuity in the refractive index. In this way, not only will the aberrations formed by the lens not meet the actual requirements, but also serious cross talk will occur when the stereoscopic display displays images, resulting in poor image display quality. Contents of the invention [0003] An object of the present invention is to provide a liquid crystal lens to improve the deterioration of the lens quality caused by the obvious discontinuity of the refractive index. [0004] Another object of t...
