Description

LED polarisation stereoscopic display screen

Technical field

The utility model relates to LED stereo display technique field, in particular to a kind of new structural LED polarisation solid is aobvious Display screen.

Background technique

The principle of 3D three-dimensional imaging is to allow the right and left eyes of people to watch the different two width figures of same object but visual angle respectively Piece can form the principle of stereo-picture using the binocular parallax of people, show in plane and generate stereo display effect on medium.Viewing It when active 3D image, needs to wear shutter liquid crystal glasses, the time difference switched using light valve liquid crystal glasses, makes the left side of people Right eye alternately watches image, allows left eye to see left-eye image, right eye sees eye image.Glasses and video image switch same stepping Row, the switch speed of image commonly reach 120 frames/second, and under the influence of human eye vision persistence characteristic, left images are in human brain Middle synthesis generates the 3D stereoscopic depth of perception of flat image.

Shutter 3D display device inter-compatibility in the market, the GPU of specific company, cannot not drive 3D system. Liquid crystal 3-D spectacles must be worn watching active 3D display, and the characteristics of 3D glasses is that have stroboscopic and be easy by other masters The interference of dynamic light source, therefore it is required that indoors observation effect is preferred LED display, and the refresh rate of display screen body must reach 1800Hz or more could eliminate the flickering of screen body when bringing viewing since indoor scan screen refresh rate is too low.Meanwhile liquid crystal For the light transmittance of glasses generally all within 60%, screen body brightness also preferably must be held in a suitable numerical value, to draw when guaranteeing viewing Face it is clear.

3D glasses need to be equipped with battery, and the electromagnetic wave emitted while a battery produces current generates radiation.3D The problem of glasses flash is mainly reflected in shutter type 3 D spectacles, and the frequency being opened and closed at left and right sides of 3D glasses is 50/60Hz, That is two eyeglasses are per second will respectively to be opened and closed 50/60 time, even so quickly, user's glasses are still that can feel to obtain, If watched for a long time, the burden of eyeball will be will increase.Different frame variation break times and individual difference are different, glasses it is tired Phenomena such as labor degree and the tired speed of brain are also different, and the long-time viewing of most serious may cause vomiting.
