Abstract: A method of increasing the brightness of a pulse width modulation display system. Image bits are displayed during display periods having a non-binary relationship. The display period of an object bit 902 is set equal to a minimum data load time, and the display periods of all other bits are initially set to have a binary relationship with the object bit. The display periods of at least one non-object bit 904, 906, 908 are then reduced in order to reduce the total frame time to no more than the available useable frame time 910. Preferably, only the display periods of bit of significance greater than the object bit are reduced. The reduction of display periods is guided by Weber's law, in order to prevent the non-binary steps from being noticeable or objectionable to the viewer.
