An apparatus ( 200 ) for driving a display ( 310, 320 ) including an array of display elements ( 20 ), each element ( 20 ) comprising a plurality of sub-pixels of red (R), green (G), blue (B) and white (W) colors. The apparatus ( 200 ) comprising a processor ( 300 ) operable: (a) to receive input signals (RI, GI, BI) for controlling red, green and blue colors of each element ( 20 ) of the display ( 320 ); (b) to process the input signals (RI, GI, BI) to generate corresponding red, green, blue and white output drive signals for the red (R), green (G), blue (B) and white (W) sub-pixels of each element ( 20 ), said output drive signals being enhanced according to a gain factor (HS) for increasing element luminosity subject to potential color saturation occurring at one or more of the elements ( 20 ) being addressed by selectively reducing color saturation at said one or more of said elements ( 20 ); and (c) to apply said output drive signals to respective sub-pixels (R; G, B, W) for each element ( 20 ) of the display ( 320 ).
