Abstract:
A multiple backlight display system includes a display device having a light guide device including a plurality of edges. An edge backlight device is located along one of the edges of the light guide device. An array backlight device includes a plurality of array backlight zones that are located between the edges of the light guide device. A computing device receives an image for display on the display device and determines a plurality of brightness zones in the image. The computing device then generates backlight driving information using the plurality of brightness zones and provides the backlight driving information to the display device. The backlight driving information is configured to drive the array backlight device such a first array backlight zone provides light having a first brightness that is different than a second brightness of light that is provided by at least one second array backlight zone.
