1. A display device, comprising:
a pixel light-emitting panel, comprising an N1 number of light-emitting pixel units distributed in an array, wherein the light-emitting pixel units are driven to emit light through a driver; and
a plurality of color conversion panels, comprising at least a first color conversion panel, a second color conversion panel and a third color conversion panel, wherein
the first color conversion panel comprises an N2 number of first color pixels and an N3 number of first transparent pixels, the first color pixels and the first transparent pixels are disposed relative to the light-emitting pixel units,
the second color conversion panel comprises an N4 number of second color pixels and an N5 number of second transparent pixels, the second color pixels and the second transparent pixels are disposed relative to the light-emitting pixel units, lights generated by at least part of the light-emitting pixel units sequentially pass through the first color pixels and the second transparent pixels to achieve a color conversion to form a color front image, and lights generated by at least part of the light-emitting pixel units sequentially pass through the first transparent pixels and the second color pixels to achieve a color conversion to form a color rear image, and
the third color conversion panel comprises an N6 number of third color pixels and an N7 number of third transparent pixels, the lights generated by at least part of the light-emitting pixel units sequentially pass through the first transparent pixels, the second transparent pixels, and the third color pixels to achieve the color conversion, and N3=N4+N6, N5=N2+N6, N7=N2+N4.
