3D (3-Dimensional) display system

Abstract

The invention is suitable for the technical field of display and provides a 3D (3-Dimensional) display system. The system comprises a signal decomposition unit, a projection and display apparatus and a polarization regulator. The 3D display system is characterized in that: firstly, a 3D video signal is decomposed into six signals of red, green and blue of the left and right eyes; the red light and blue light of the left eye and the green light of the right eye are taken as an optical signal, and the red light and the blue light of the right eye and the green light of the left eye are taken as another optical signal, and the two optical signals are alternately output at different moments; next, the polarization state of one optical signal is adjusted by means of the own polarization characteristics of the three-color light of red, green and blue recombined after decomposition, and finally, the polarization state of a left-eye image signal is different from that of a right-eye image signal projected to the same screen. At the moment, 3D display can be realized without adding a polarizer; and the light energy utilization efficiency of the 3D display system is greatly improved. Besides, the 3D display system provided by the embodiment of the invention realizes 3D display through only one projection and display apparatus; and therefore, the system structure is simplified and the cost is greatly reduced.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a 3D display system. Background technique [0002] At present, there are three kinds of projection display technologies: LCD, DLP and LCOS. The efficiency of single-plate LCD and LCOS is generally low. In order to improve optical efficiency, 3-plate LCD and 3-plate LCOS generally adopt SPS color combination technology. In the optical part of the projector output, it is basically necessary to add double polarizers. The final The light effect is less than 1 / 4 of that of ordinary projection, and the utilization efficiency is very low. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a 3D display system, aiming at solving the problem of low utilization rate of light energy in the existing 3D display system. [0004] The embodiment of the present invention is achieved in this way, a 3D display system includes: [0005] Sign...
