Projection optical engine, electronic device, and projection imaging method

A projection imaging method, wherein the method is applied to a projection optical engine, and

• the projection optical engine comprises:
• a first display panel, wherein the first display panel comprises a plurality of pixels of a first color, and the pixel of the first color comprises an active light-emitting device;
• a second display panel, wherein the second display panel comprises a plurality of pixels of a second color, and the pixel of the second color comprises an active light-emitting device;
• and
• a light combination apparatus, a pixel expansion apparatus, and an optical engine lens;
• the projection imaging method comprises:
• combining, by using the light combination apparatus, light emitted by the pixel of the first color and light emitted by the pixel of the second color, and then emitting combined light;
• the projection optical engine works in a plurality of cycles, and each cycle comprises a first moment and a second moment;
• at the first moment, the light emitted by the light combination apparatus is imaged in a first location region on an imaging plane after passing through the pixel expansion apparatus and the optical engine lens;
• and
• at the second moment, the light emitted by the light combination apparatus is imaged in a second location region on the imaging plane after passing through the pixel expansion apparatus and the optical engine lens, wherein the second location region is offset relative to the first location region.
