Disclosed embodiments comprise dynamic pulse width modulation (PWM) bit sequence selection techniques for use with video display devices. By dynamically selecting and applying a bit sequence based on the display image content and the limited dynamic range of human perception, the bit sequence used to display a given scene may be optimized in order to provide for increased bit depth or increased brightness. Generally one out of a plurality of available bit sequences would be applied to a given scene, with different bit sequences designated for displaying bright scenes and dark scenes. Alternatively, different bit sequences may be applied depending upon the amount of motion in a scene. Thus, a dynamic bit sequence selection technique may allow for a display device with increased bit depth and increased brightness.
