Embodiment 1

[0042] The structure of the display device is as figure 1 As shown, wherein, the lenticular lens film is a concave lens film, the material of the film has a refractive index n, the electro-optic material is a liquid crystal molecule, and the minimum and maximum values ​​of the refractive index are respectively n o (i.e. n 1 ) and n e (i.e. n 2 ), where n-n o e -n.

[0043] The voltage applied to the display device is 0V, ie V OFF =0V, at this time, the direction of the optical axis of the liquid crystal molecules is parallel to the polarization direction of the image light, so that the refractive index of the liquid crystal molecules is felt by the abnormal light refractive index n e , when the image light passes through the concave lens in the plano-concave lens film, it feels the effect of the convex lens to realize 3D display.

[0044] The applied voltage of the display device is adjusted so that the effective refractive index of the liquid crystal molecules is strict...

Abstract

The invention provides a display device and a 2D display mode realization method. The display device comprises a visual scene separation structural layer and an electro-optical material. The realization method comprises the steps of applying a voltage to the display device and adjusting the voltage to V1 till the refractive index of the electro-optical material is equal to that of the visual scene separation structural layer, wherein the display device is in a 2D display mode at the moment. Through adoption of the realization method, the phenomenon that requirements on the refractive index setting of the visual scene separation structural layer and a preparation process of the display device are high in the prior art is relieved, and a lens residue phenomenon caused by non-strictly equal refractive indexes of the electro-optical material and the visual scene separation structural layer in the prior art is overcome; therefore, the 2D display effect of the display device is good.

Description

technical field [0001] The present application relates to the field of 2D / 3D display, in particular, to a display device and a method for realizing the 2D display mode thereof. Background technique [0002] In the prior art, in a 2D / 3D switchable display device, the combination of a visual separation structure layer and an electro-optical material (such as a liquid crystal material) is used to realize switching between 2D mode and 3D mode. Electro-optic materials have different refractive indices under different voltages. When the voltage V between the electrodes of the display device OFF , its refractive index n 1 , at V ON , its refractive index n 2 . The refractive index of the visual separation structure layer material needs to be equal to n 1 or n 2 , so as to realize the 2D display of the display device. [0003] When the refractive index of the view separation structure layer is equal to n 1 , and when the refractive index of the electro-optic material is also...
