2D/3D switchable stereo display device

Abstract

The invention belongs to the technical field of stereo display and particularly relates to a 2D / 3D switchable stereo display device which comprises a display panel and a liquid crystal lens arranged on the light outlet side of the display panel. The liquid crystal lens comprises a first substrate, a second substrate, liquid crystal molecules and interstitials, wherein the first substrate and the second substrate are oppositely arranged, and the liquid crystal molecules and the interstitials are arranged between the first substrate and the second substrate. The first substrate is provided with a plurality of first electrodes, every two adjacent first electrodes is at a certain interval, the second substrate is provided with second electrodes, and the 2D / 3D switchable stereo display device further comprises a control module which is used for controlling first voltage exerted between the first substrate and the second substrate. When the 2D / 3D switchable stereo display device is in 2D display, the first voltage generates a first electric field equal in electric field intensity, the first electric field drives the liquid crystal molecules to be deflected, so that the refractivity between the liquid crystal molecules and the interstitials is within a preset range, and the problem that due to the refractivity, light is refracted at the interstitial positions, bright spots or color spots occur at the interstitial positions and viewing effect is affected is solved.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, and in particular relates to a 2D / 3D switchable stereoscopic display device. Background technique [0002] Humans perceive the depth of objects through the slight difference between what the right and left eyes see, and thus recognize stereoscopic images. This difference is called parallax. Stereoscopic display technology is to create the parallax of the left and right eyes of people through artificial means, and send two images with parallax to the left and right eyes respectively, so that the brain can observe the real three-dimensional objects after obtaining the different images seen by the left and right eyes. a feeling of. [0003] With the continuous deepening of people's understanding of liquid crystal materials, liquid crystal lenses made of liquid crystal materials have a wide range of applications, such as in the field of three-dimensional display. figure 1 A schematic s...

Problems solved by technology

When the 2D / 3D switchable stereoscopic display device is in the 2D display state, when the light emitted by the display panel 1' passes through the spacer 24' and the liquid crystal molecules 23' near the spacer 24', at this time, the refractive index of the spacer 24' The refractive index difference with the liquid crystal molecules 23' is large, and the light is refracted at the spacer 24'. When the human eye looks at the liquid crystal lens 2', bright spots or colored spots appear at the spacer 24', which affects the viewing effect of the viewer. and viewing comfort

[0004] The prior art discloses a stereoscopic display device, which includes a display panel and a liquid crystal lens grating. The display panel includes a plurality of pixel units and a black matrix arranged between the plurality of pixel units. The liquid crystal lens grating includes spacers whose positions are Corresponding to the position of the black matrix in the display panel, setting the black matrix in the display panel not only affects the display effect of the display panel, but also the black matrix cannot completely cover the gaps, resulting in bright spots still appearing at the gaps when viewed by human eyes
