Embodiment Construction

[0030] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. For the convenience of describing the embodiment of the present invention, the direction parallel to the bottom of the display device shown in the drawings in all the drawings is referred to as the horizontal direction below, and the calculation of any inclination angle shall take this horizontal direction as the reference direction, and will be directly opposite to When viewed by the display device, the counterclockwise direction is regarded as the positive direction of the angle.

[0031] An embodiment of the present invention provides a low-scattering 2D-3D switchable stereoscopic display device, which sequentially includes a display device, a polarized light conversion device, and a birefringent combination lens along the direction of an optical path. Wherein, the birefringent combined lens includes: a convex lens array and a concave lens array, and ...

Abstract

The invention discloses a stereoscopic display device in low scattering 2D-3D switching type, which comprises a display device, a polarized light converting device and a birefringent combined lens. The birefringent combined lens comprises a plurality of parallel grooves and a liquid crystal material with the orientation parallel to the direction of the grooves; the direction of the grooves and any group of parallel stripes in the two-dimensional structure light filed of the display device form a special included angle; the polarized light converting device leads linearly polarized light provided by the display device to carry out controllable rotary or direct transmission so as to provide two linearly polarized light with polarization directions vertical to each other and the polarizationdirection of one of the linearly polarized light being parallel to the liquid crystal orientation of the birefringent combined lens; the two linearly polarized light with the polarization directions vertical to each other and provided by the polarized light converting device is shown by the birefringent combined lens as a convex lens and a plano lens. The stereoscopic display device in the low scattering 2D-3D switching type has high display clearness and does not have the phenomenon of blanching of the display device when being turned off.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a low-scattering 2D-3D switchable stereoscopic display device. Background technique [0002] With the development of stereoscopic display technology, 2D-3D switching stereoscopic display devices have emerged as the times require. This type of display device can display two-dimensional images or three-dimensional images according to the needs of viewers. Compared with display devices that only have a single stereoscopic display function , with broader market prospects. [0003] figure 1 It is an existing 2D-3D switching stereoscopic display device, which includes: a liquid crystal display 11 , a twisted nematic liquid crystal cell 12 and a birefringent combination lens 13 . Wherein, the liquid crystal display 11 is used for displaying a planar image in which the emitted light is horizontal / vertical linearly polarized light, that is, provides the twisted nematic liquid crystal...
