Three-dimensional display device and system, and three-dimensional display method

Abstract

The invention relates to a three-dimensional display device, which comprises an inner polaroid, an outer polaroid and a display base plate arranged between the inner polaroid and the outer polaroid. The inner polaroid is provided with staggered first polarizing region and second polarizing region, wherein the difference of polarizing angles of the first polarizing region and the second polarizingregion is 90 degrees. The outer polaroid is provided with a third polarizing region and a fourth polarizing region of which the arrangement positions correspond to the first polarizing region and thesecond polarizing region, wherein the difference of the polarizing angles of the third polarizing region and the first polarizing region is 90 degrees, and the difference of the polarizing angles of the fourth polarizing region and the second polarizing region is 90 degrees. The light beams passing through the first polarizing region can just pass through the third polarizing region after passingthrough the base plate so as to pass through one lens of a pair of three-dimensional glasses; and the light beams passing through the second polarizing region can just pass through the fourth polarizing region after passing through the base plate so as to pass through the other lens of the pair of the three-dimensional glasses, so a three-dimensional visual effect is generated.

Description

technical field [0001] The invention relates to a stereoscopic display technology of a liquid crystal display device, in particular to a stereoscopic display technology capable of producing a stereoscopic effect by changing the polarizer in the original liquid crystal display device. Background technique [0002] If you want to make a flat screen display a three-dimensional effect, you need to apply the principle of stereo vision, that is, send the image you want to see to the left eye to the left eye, and send the image you want to see to the right eye to the right eye. After processing by the brain, it will form Stereoscopic images. [0003] For 3D movies, it can be produced using the principle of polarization imaging: use two cameras with slightly different angles to shoot left-eye images and right-eye images, and then perform horizontal polarization processing and vertical polarization processing respectively before projecting them on the screen. When viewers want to wa...
