A color display panel comprises at least one pixel. The pixel comprises a sub-pixel circuit of a type comprising a light-emitting cell ( 13 ) for emitting light with a first spectral distribution when a voltage in a first operating range is applied, and for emitting light with a different spectral distribution when a voltage in a second operating range is applied. The color display panel further comprises at least one data line ( 8 ) for passing a signal controlling the emission of light by the light-emitting cell to the first sub-pixel circuit. The sub-pixel circuit further comprises at least two active components ( 9, 10 ) for applying respective voltages to the cell ( 13 ) in dependence on respective reference voltages under control of the signal.
