Abstract
The present invention provides an image processing method, system for laser TV and the laser TV set thereof, which receives a TV signal before converting into ultra high definition images sequences; whose each image is then segmented and converted into two frames of image, and two sequences of image will then be obtained; which are then driven by two DMD driving chips and displayed in a time share and diagonal staggered way during a period satisfying a visual persistence. The present invention utilizes a principle of visual persistence, since two frames of image segmented from a frame of ultra high definition image may be processed at a same time by two existing DMD driving chips being able to process FHD images, and both frames of image may be displayed at different positions on the screen at different time, forming one frame of ultra high definition image in a human's vision. The present invention owns a simple method, which utilizes an existing FHD element and achieves an ultra high definition display, has a low cost and a wide application.
