Display module and imaging method

An imaging method, wherein the method is applied to a display, the display comprises a self-luminous array, a pixel expansion apparatus, and a lens of an optical engine, the self-luminous array comprises a plurality of self-luminous pixels, the pixel expansion apparatus comprises a driver and a transparent flat plate, and the method comprises:

• separately emitting, by the plurality of self-luminous pixels of the self-luminous array, light beams, wherein the light beams are imaged on an imaging plane of the lens of the optical engine through the transparent flat plate, wherein a color of a light beam emitted by a first self-luminous pixel in the plurality of self-luminous pixels is different from a color of a light beam emitted by a second self-luminous pixel, and wherein the first self-luminous pixel is adjacent to the second self-luminous pixel;
• and
• wherein the transparent flat plate is driven by the driver to rotate in a time-division manner, wherein a first area on the imaging plane of the lens of the optical engine displays different colors in the time-division manner, the different colors being produced by imaging, in different time units, light beams emitted by different self-luminous pixels of the plurality of self-luminous pixels onto the same first area, and wherein the first area is any unit imaging area in an imaging area of the imaging plane.
