Classification: CPC G | IPC C  G  H

Claim 6:
7. A display device, wherein the display device comprises a plurality of pixels, wherein one of the pixels comprises a first control circuit and a first sub-pixel, wherein the first sub-pixel comprises first light emitting element with a first peak wavelength, wherein the first control circuit is coupled with the first light emitting element, wherein another of the pixels comprises a second control circuit and a second sub-pixel, wherein the first sub-pixel and the second sub-pixel are the same color sub-pixels, wherein the second sub-pixel comprises a second light emitting element with a second peak wavelength different from the first peak wavelength, wherein the second control circuit is coupled with the second light emitting element, and wherein:
the first control circuit is configured to provide a first driving current with a first pulse amplitude to the first light emitting element, wherein the first pulse amplitude is set to adjust the first peak wavelength of the first light emitting element toward a target wavelength; and
the second control circuit is configured to provide a second driving current with a second pulse amplitude to the second light emitting element, wherein the second pulse amplitude is set to be different from the first pulse amplitude to adjust the second peak wavelength of the second light emitting element toward the target wavelength, such that the first light emitting element and the second light emitting element emit at the target wavelength or a color point range.
