Problems solved by technology

[0004] However, the usual way to scan the display screen is from left to right and from top to bottom. Due to the speed limit of the galvanometer, a fixed number of frames per second is scanned, resulting in the frame rate of the video image cannot be increased.

Abstract

The invention provides a three-level video information transmission system for full-laser projection. Video signals in the three-level video information transmission system are input and then subjected to pixel point reforming, segmenting and packaging processing through the first-level processing subsystem to be distributed to the multiple sets of second-level processing subsystems. The secondaryprocessing subsystem decodes, divides, packages and distributes to the multiple groups of tertiary processing subsystems, the multiple groups of LDs are driven at the same time after being processedby the tertiary processing subsystems, pixel scanning is realized through galvanometer driving, display of a frame of image is completed, and the frame rate and brightness are greatly improved.

Description

technical field [0001] The invention relates to the technical field of laser projection and video signal processing, and more specifically, relates to a three-stage video information transmission system for full laser projection. Background technique [0002] Laser projection display technology is a display technology that uses RGB three primary color lasers as the light source. Among the many different forms of display technologies at present, laser display technology represents the trend and mainstream direction of the future development of display technology, and is the focus of future competition in the display field. Engineering projection and digital cinema based on modern digital technology are solving the resolution and clarity of video images, including signal acquisition, processing, storage, transmission and reproduction. [0003] Both interlaced scanning and progressive scanning are methods of reproducing video images. The interlaced scanning method is that each...
