Abstract
The present disclosure relates to a display panel. The display panel includes a light switching layer, and a color film layer located on the light switching layer, wherein the color film layer includes a diffraction grating. The color film layer further includes a collimating layer located on a side of the diffraction grating facing away from the light switching layer. The color film layer further includes a light splitting layer located between the diffraction grating and the light switching layer.
Claims10
A display panel comprising:
- a light switching layer;
- a color film layer located on the light switching layer;
- and
- a scattering layer, wherein the scattering layer is located one of i) between the light switching layer and the color film layer and ii) on a side of the light switching layer facing away from the color film layer,
- wherein the color film layer comprises a diffraction grating, and a light splitting layer located between the diffraction grating and the light switching layer,
- wherein light transmitted through the diffraction grating is completely separated after passing through the light splitting layer, so as to obtain separated monochromatic lights of different colors.
