High-resolution projection display method capable of completely copying pixels

The invention discloses a high-resolution projection display method capable of completely copying pixels, which is realized by utilizing a projection system, and the projection system comprises an image processing control unit, a micro display chip, a pixel copying module, a projection objective lens and a projection screen, the method comprises the steps that the image processing control unit controls image scanning of the micro-display chip and deflection of the pixel copying module at the same time, an image of the micro-display chip passes through the pixel copying module and then is amplified by the projection objective to be imaged on the projection screen, and uniform pixel gaps exist in physical pixels on the micro-display chip in the row and/or column direction. The width of each pixel gap is an integral multiple of the size of a single physical pixel, and the pixel gaps are filled after projection of the micro-display chip, so that projection display of the whole image is completed.
