Anti-reflective electrically-driven 3D liquid crystal lens

Abstract

The invention relates to an anti-reflective electrically-driven 3D liquid crystal lens. The anti-reflective electrically-driven 3D liquid crystal lens comprises a first substrate, a second substrate, a first alignment layer, a first electrode, a second alignment layer and a second electrode, wherein the first alignment layer and the first electrode are arranged on the inner side of the first substrate, and the second alignment layer and the second electrode are arranged on the inner side of the second substrate. A liquid crystal layer is arranged between the first substrate and the second substrate. The first electrode is a whole-face continuous electrode, and the second electrode is composed of a plurality of side-by-side linear electrodes. A first anti-reflective layer is arranged between the first electrode and the first substrate and is a transparent insulating film layer. The overall refractive rate of the first anti-reflective layer is larger than the refractive rate of the first substrate and smaller than the refractive rate of the first electrode. By arranging the first anti-reflective layer between the first electrode and the first substrate, reflection of the film layer between the first electrode and the first substrate is reduced, and therefore the reflective rate of the 3D liquid crystal lens is greatly decreased, and an image displayed under the bright environment is made to have high contrast.

Description

technical field [0001] The invention relates to a display device, in particular to an anti-reflection electrically driven 3D liquid crystal lens. Background technique [0002] Naked-eye 3D displays generally require a 3D liquid crystal lens to be placed in front of a flat-panel display. The second alignment layer and the second electrode are formed inside the second substrate, a liquid crystal layer is arranged between the first substrate and the second substrate, and the first electrode and the second electrode are both indium tin oxide (ITO) thin films, wherein , the first electrode is a continuous electrode on the entire surface, and the second electrode is composed of a plurality of line electrodes arranged side by side. [0003] This liquid crystal lens, due to the large refractive index difference between the first electrode and the second electrode of the indium tin oxide film, the first substrate, the second substrate, the first alignment layer, and the second align...

Problems solved by technology

[0003] This liquid crystal lens, due to the large refractive index difference between the first electrode and the second electrode of the indium tin oxide film, the first substrate, the second substrate, the first alignment layer, and the second alignment layer, It will lead to obvious film reflection on the 3D liquid crystal lens, which will cause the reflectivity of the 3D display to be too large, and the contrast of the displayed picture in a brighter environment will be reduced, which will affect the user's viewing of the picture. In addition, the line Shaped electrodes are very easy to produce linear reflected light under strong light, which will also interfere with the user's viewing of the screen
