A system for cooling various components of an electronic display. During polishing, the pressure of the sealed hollow is adjusted with a pressure regulating mechanism 9 communicating with the hollow, thereby elastically deforming the diaphragm. The adjusted output power of the power converter adjusts a high end level of light output by the solid state lighting load at the maximum phase angle to match a predetermined high end value and adjusts a low end level of light output by the solid state lighting load at the minimum phase angle to match a predetermined low end value. The controller mitigates pitch motion and heave motion by adjusting a movement of the movable arm. One method includes creating halftone mask structures and applying compression coding techniques to arrayed pixels sorted using the halftone mask structures in order to convert an image to a compressed bi-level, halftoned image.
