Abstract
A method of zero-D dimming backlights for 3D or multi-view displays using right and left image data. The method receives right and left pixel luminance values for the right and left image data, and it remaps the right and left pixel luminance values using a factor based upon an average luminance value or based upon a luminance percentile value or a modified factor that further includes the absolute difference between left and right pixel luminance values. The factor or modified factor are selectively used to remap particular right and left pixel luminance values based upon a disparity consideration. The method results in power savings by dimming the backlight without perceptible or substantial loss in brightness of the display.
