Abstract
Examples of a projection optical engine, an electronic device, and a projection imaging method are described. One example of a light combination apparatus is configured to combine light emitted by one pixel of a first color and light emitted by one pixel of a second color, and then emit combined light. The light emitted by the light combination apparatus is imaged on an imaging plane after passing through a pixel expansion apparatus and an optical engine lens. The pixel expansion apparatus is configured to enable the light emitted by the light combination apparatus to be imaged at different locations on the imaging plane at different moments.
