Patent ID: 8294833

Claim:
An image projection method for projecting an image onto a display, the method comprising the steps of: a) obtaining an image pixel array for the image to be projected; b) obtaining a plurality of pixel allocation arrays for the image pixel array, each pixel allocation array including occupied elements and vacant elements; c) generating a trigger pulse train for a laser light source according to a pixel allocation array, whereby a trigger pulse is generated for each occupied element of the pixel allocation array; d) generating a modulation signal for the laser light source on the basis of the image pixel array; e) switching the laser light source with the trigger pulse train and modulating the laser light source with the modulation signal to generate a laser light pulse sequence for a sub-frame image; and f) scanning the laser light pulse sequence to traverse the display such that the sub-frame image is projected onto the display; wherein the steps c) to f) are carried out for each pixel allocation array of the plurality of pixel allocation arrays so that the image appears on the display.
