Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for enhancing display viewability in high ambient conditions without excessive increase in power consumption. In one aspect, a controller associated with the display device can be configured to obtain an indication of ambient light conditions from an ambient light sensor or from a host device hosting the display device. Upon receiving an image frame, the controller can derive a set of color subfields and determine a bit-depth value for each color subfield based on the obtained indication of current ambient light conditions and mapping data which maps ranges of ambient light to respective bit-depth values on a color subfield by color subfield basis. The controller can then generate a number of subframes for each color subfield based on the respective determined bit-depth value and cause the generated subframes to be displayed.

Abstract: Systems and methods for a display having an array of pixels, a substrate, and a control matrix formed on the substrate are described. The array of pixels includes mechanical light modulators that can be referred to as micro-electro-mechanical or MEMS light modulators. The MEMS light modulators may be shutter-based light modulators, and an array of apertures may be formed on the substrate corresponding spatially to the shutters in the array of shutter-based light modulators. Each modulator is configured to be driven from a-light-blocking state to a-light-transmissive state through a movement direction. The array of light modulators are arranged to reduce the correlations in movement directions of neighboring pixels, thereby reducing the amplitude of acoustic emissions from the display.

Abstract: A display includes pixels and a controller. The controller can cause the pixels to generate colors corresponding to an image frame. The controller can cause the display to display the image frame using sets of subframe images corresponding to contributing colors according to a field sequential color (FSC) image formation process. The contributing colors include component colors and at least one composite color, which is substantially a combination of at least two component colors. A greater number of subframe images corresponding to a first component color can be displayed relative to a number of subframe images corresponding to another component color. The display can be configured to output a given luminance of a contributing color for a first pixel by generating a first set of pixel states and output the same luminance of the contributing color for a second pixel by generating a second, different set of pixel states.
