Problems solved by technology

However, when the 2D / 3D switchable stereoscopic display device is in the two-dimensional display mode, the light emitted by each sub-pixel on the two-dimensional pixel plane of the display panel is diffused by the diffuser in its outgoing direction, so some sub-pixels emit The light from the 2D / 3D switchable stereoscopic display device cannot be completely and clearly transmitted to human eyes, resulting in fuzzy display of the 2D / 3D switchable stereoscopic display device.

Embodiment 1

[0043] Example 1 Figure 5 Shown is a schematic diagram of a detailed structure of a 2D / 3D switchable stereoscopic display device provided in Embodiment 1 of the present invention. Such as Figure 5 As shown in , the 2D / 3D switchable stereoscopic display device includes: a display panel 51 providing two-dimensional images, a PDLC cell whose scattering degree is controlled by a voltage control unit 54, and a 2D / 3D switching device.

[0044] The PDLC cell is composed of two substrates 53a, 53b carrying transparent electrodes and a PDLC material 52 encapsulated between 53a and 53b. The transparent electrodes (not shown) on the two substrates 53a, 53b are electrically connected to the voltage output terminals A, B of the voltage control unit 54, respectively.

[0045] The 2D / 3D switching device specifically includes: a polarization conversion device responsible for rotating the vibration direction of the linearly polarized light provided by the PDLC cell by 90 degrees in 2D and ...

Embodiment 2

[0048] Example 2 Figure 7 Shown is a schematic diagram of a detailed structure of a 2D / 3D switchable stereoscopic display device provided by Embodiment 2 of the present invention.

[0049] Such as Figure 7 As shown in , the 2D / 3D switchable stereoscopic display device includes: a display panel 71 , a PDLC box 72 with adjustable scattering rate and a 2D / 3D switching device 73 . Wherein, the 2D / 3D switching device 73 specifically includes: a rod lens grating 75 made of birefringent material, a substrate 76 with a flat surface, and twisted liquid crystal 78 filled between the rod lens grating 75 and the substrate 76 . Wherein, the side of the cylindrical lens grating 75 facing the outgoing surface of the PDLC box 72 is a plane, and the opposite surface of the plane is a convex (or concave) surface with a plurality of semi-cylindrical lenses arranged in parallel, and the generatrix of each cylindrical surface is connected to the two-dimensional pixel The columns of the matrix ...

Abstract

The invention discloses a 2D / 3D switchable three dimensional display device, which not only includes display panel and 2D / 3D switchable device, but also includes a polymer dispersed liquid crystal PDLC device with adjustable scattered rate, which is equipped between the display panel and the 2D / 3D switchable device. The PDLC device is used to cause the emergent light of display panel to scatter or directly transmit to the 2D / 3D switchable device. In the 2D / 3D switchable three dimensional display device provided by the invention, because the PDLC device could cause the emergent light of display panel to scatter, the Moire fringe produced by mutualinterference between the display panel and the 2D / 3D switchable device can be eliminated.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a 2D / 3D switchable stereoscopic display device. Background technique [0002] With the development of display technology, a 2D / 3D switchable stereoscopic display device has become a new research direction in the field of stereoscopic display. Compared with the stereoscopic display device with only a single stereoscopic display function, the 2D / 3D switchable stereoscopic display device can allow users to freely choose to use the two-dimensional display mode or the three-dimensional display mode for viewing. Therefore, this kind of display device has greater practical value . [0003] figure 1 Shown is a schematic structural diagram of an existing 2D / 3D switchable stereoscopic display device, which mainly includes a display panel 11 and a 2D / 3D switching device 12 . Wherein, the outgoing light of the display panel in the more common 2D / 3D switchable stereoscopic display devic...
