<p>A light emitting diode (LED) driver (4) for an LED backlighting system in a display. The driver includes an input (22) for receiving a driver signal. A correction unit applies a non-linear correction to the driver signal to produce a gamma corrected driver signal. The gamma correction compensates for the non-linear perceptual response of the human eye to luminance information. The LED driver also includes an output (24) for outputting the gamma corrected driver signal to one or more LEDs (2).</p> |
