Abstract

The invention discloses a polarized three-dimensional (3D) display device and system. The system comprises a polarized 3D display device which generates circularly polarized light through scanning image signals, and circular polarizing glasses receiving the circularly polarized light; during the process of scanning the image signals by the polarized 3D display device, light-valve liquid crystal is rotated, and the circularly polarized light emitted by a light valve is obtained according to an angle between a polarizing plate and the light valve; the circular polarizing glasses have left and right lenses; and each of the lens is formed by adhering a 1 / 4 lambda wave plate and the polarizing plate and is respectively used for receiving the circularly polarized light opposite to a polarizing state direction. In match with the circular polarizing glasses, when the circularly polarized light emitted by the light valve shakes above heads of observers, a frosting phenomenon described by a Malus law is not generated, so that the frosting phenomenon caused by the observers of rotating heads left and right is avoided; an observing effect is improved; and an observing experience of the observers is improved.

Description

technical field [0001] The present invention relates to the field of 3D display, and more specifically, relates to a polarized 3D display device and system. Background technique [0002] With the continuous development of modern science and technology, multimedia display technology has also been developed rapidly, making people feel clear and real when watching videos or movies. In order to further enhance people's viewing experience, more real and clear display Technology, that is, 3D display technology has also developed rapidly. [0003] 3D display technology utilizes the principle of human binocular parallax, that is, people's left and right eyes receive different images, and then the brain superimposes and regenerates the image information to form a three-dimensional image with front-back, up-down, left-right, far-near, etc. The image with directional effect makes people feel like they are there when watching a film or video. In order to realize this stereoscopic effe...
