Claim 9:
10. A method for driving a display panel comprising a plurality of pixels, each of the plurality of pixels comprising a plurality of main sub-pixels and a backup sub-pixel, the method comprising:
detecting whether there is a failed main sub-pixel in each of the plurality of pixels, wherein for any one of the plurality of pixels, if there is a failed main sub-pixel, the backup sub-pixel cooperates with normal main sub-pixels to output metamerized light of a target color; otherwise, the backup sub-pixel does not work, and the plurality of main sub-pixels outputs the target color;
wherein 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;
the method further comprises independently adjusting spectral power distribution of the red light converted from the blue light, spectral power distribution of the green light converted from the blue light, and spectral power distribution of the blue light with the desired wavelength band converted from the blue light to output metamerized light of the target color.
