Abstract
The invention discloses an optical-waveguide display module with multiple light sources, including a light-source array of timing-orthogonal-characteristic, a relay device, a display device of orthogonal-characteristic, an optical waveguide device, a converging device, a control device, and other components. The light-source array of timing-orthogonal-characteristic includes more than one orthogonal-characteristic light sources. All orthogonal-characteristic light sources are switched on and off in each time cycle sequentially, with only one orthogonal-characteristic light source being switched on at a time-point of each time cycle. By designing the spatial distribution of converging spots of lights from different orthogonal-characteristic light sources, one two-dimensional image is projected into the pupil of the viewer in each time cycle, which realizes VAC-free three-dimensional display based on Maxwellian view technology or More-than-one-view-one-pupil technology.
