<p>A backlit display with improved display characteristics is provided in which the light sources comprise LEDs arranged in rows and columns. A data processing unit provides a signal to a light driver to select the appropriate light source corresponding to a displayed pixel and drives the light source with a power level to produce an appropriate level of illumination, the light source of each region of the display being independent of those of other regions. For each region, motion detection (308) is performed in order to determine it is a motion block or a still block. A screen is then generated (310) based on a motion map, and a screen function may be changed (312) to determine which backlight to illuminate and the level of illumination.</p> |
