Passive circular polarization 3D LED display screen module, passive circular polarization 3D LED display device and passive circular polarization 3D LED display system

Abstract

The invention is suitable for the technical field of 3D display, and provides a passive circular polarization 3D LED display screen module, a passive circular polarization 3D LED display device and a passive circular polarization 3D LED display system. The passive circular polarization 3D LED display screen module comprises an LED pixel lamp array formed by a plurality of LED pixel lamps arranged in an array form, and further comprises a circular polarizing film array set on a light-out surface of the passive circular polarization 3D LED display screen module, wherein the circular polarizing film array comprises a plurality of circular polarizing films composed of levorotation circular polarizing films and dextrorotation circular polarizing films which are alternatively arranged in a row and / or column direction, and the number of the circular polarizing films is equal to that of a plurality of LED pixel lamps. According to the invention, by means directly setting the alternatively arranged levorotation circular polarizing films and dextrorotation circular polarizing films at the pixel lamp array, a tedious work of precise location for a polarization axis direction of the polarizing film of each pixel point can be avoided effectively, a problem of generation of 3D image ghosting, flickering vision of human eyes, easily produced visual fatigue and uncomfortable sense during watching caused by head swinging of audiences is avoided, and visual angle of stereo images also can be expanded.

Description

technical field [0001] The invention belongs to the technical field of 3D display, and in particular relates to a passive circularly polarized 3D LED display module, a display device and a system. Background technique [0002] 3D technology can make the picture three-dimensional and realistic, and the image is no longer limited to the plane of the screen, as if it can go out of the screen, so that the audience has an immersive feeling. 3D display screens based on 3D technology mainly include: color difference type, polarized light type and active shutter type. [0003] However, the existing shutter-type 3D display screens require images to be quickly switched between left and right eyes, resulting in visual flickering of the human eye, visual fatigue, and uncomfortable viewing; polarized display screens need to strictly ensure that the direction of the polarization axis of the polarizer is correct. There are tens of thousands of pixels on the display, and the workload of en...

Problems solved by technology

[0004] The purpose of the present invention is to provide a passive circularly polarized 3D LED display module, display device and system, aiming to solve the problem that the existing shutter-type 3D display screen needs to quickly switch images between the left and right eyes, resulting in human visual flickering and easy Visual fatigue and uncomfortable viewing; Polarized display screens need to strictly ensure that the direction of the polarization axis of the polarizer is correct. For thousands of pixels on the display, the workload of ensuring the direction of the polarization axis is quite cumbersome, and it is difficult to ensure that each pixel The polarizing axis directions of the polarizers of the points are all fitted correctly, which affects the overall 3D display effect
