1. A display panel comprising a plurality of pixels, wherein each of the plurality of pixels comprising a plurality of main sub-pixels and a backup sub-pixel, and for any one of the plurality of pixels, if there is a failed main sub-pixel, the backup sub-pixel is configured for cooperating with normal main sub-pixels to output metamerized light of a target color;
the backup sub-pixel comprises:
a first backup light-emitting element for emitting blue light;
a second backup light-emitting element for emitting blue light;
a third backup light-emitting element for emitting blue light;
a red conversion block on the first backup light-emitting element and configured for converting the blue light emitted by the first backup light-emitting element into red light;
a green conversion block on the second backup light-emitting element and configured for converting the blue light emitted by the second backup light-emitting element into green light; and
a blue conversion block on the third backup light-emitting element and configured for converting the blue light emitted by the third backup light-emitting element into blue light with a desired wavelength band.
