Classification: CPC G | IPC C  G  H

Claim 7:
8. A driving method for operating a display device, wherein the display device comprises a plurality of sub-pixels, wherein the sub-pixels comprise a first sub-pixel and a second sub-pixel, wherein the first sub-pixel and the second sub-pixel are the same color sub-pixels, wherein the first sub-pixel comprises a first light emitting element with a first peak wavelength, wherein the second sub-pixel comprises a second light emitting element with a second peak wavelength different from the first peak wavelength, wherein the driving method comprising:
providing 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
providing 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 both of the first light emitting element and the second light emitting element emit at the target wavelength or in a color point range.
