LED video processor with 3D synchronization function

Technical Field

The utility model relates to an image processing correlation technique field among the full-color large screen display system of LED specifically is LED video processor who has 3D synchronization function.

Background

3D display technology related to LED display screens has become a new research field and direction; by utilizing the parallax principle, when a viewer watches a picture, only two groups of images with slightly staggered shooting positions are provided for the left eye and the right eye to watch respectively, so that a group of pictures with stereoscopic impression can be seen; the parallax error principle is used as the basis for the fact that the parallax error is not separated from the original image. The two sets of pictures are alternately played in a very short time, specifically, the picture entering the left eye of a viewer is played by the LED display screen during the first refreshing, the right eye of the viewer is shielded by the glasses worn by the viewer, and the left and right directions are switched during the next refreshing; continuously exchanging the two actions, namely switching two sets of shutter pictures at high speed, and finally forming continuous 3D pictures by using the persistence characteristics of human eyes and the synthetic action of brain;

at present, widely used glasses are liquid crystal shutter glasses capable of continuously shielding left and right eyes at a high speed, the method has high synchronization requirements on an LED display screen and the liquid crystal shutter glasses, special wireless transmitting equipment needs to be added to synchronize the LED display screen and the liquid crystal shutter glasses, and the cost is increased, so that an LED video processor with a 3D synchronization function is designed and produced, and the problems are solved.
