Abstract: This disclosure provides systems, methods, and apparatus for providing protective coatings on electromechanical systems (EMS) devices. A display apparatus can include an electrostatic actuation assembly for controlling the position of a suspended portion of a display element. The electrostatic actuation assembly can include a load beam, drive beam, and a coating disposed over a portion of the drive beam. The coating can include a plurality of raised tabs spaced apart from each other. One or both of the size of the raised tabs and a pitch between raised tabs can be varied along a surface of the drive beam. The voltage used to actuate the actuator is, in part, related to the shape and relative position of the load and drive beams. The raised tabs can be sized, spaced, or positioned to affect a desired rest position and rest shape of the drive beam relative to the load beam.

Abstract: This disclosure provides systems, methods, and apparatus for generating images on a multi-primary display. A multi-primary display can include control logic that converts input image data into the multi-primary color space employed by the display by mapping the input pixel values into an intermediate color space according to a gamut mapping function and then decomposing the mapped pixel values into color subfields associated with the display's primary colors. The control logic can be configured to identify a lossy gamut mapping saturation parameter value to use in the gamut mapping process which results in a power-saving desaturated image that is perceived by the Human Visual System (HVS) as substantially maintaining its color fidelity.

Abstract: Systems, methods and apparatus, including computer programs encoded on computer storage media, of this disclosure allow for forming an image frame on a display device. In one aspect, a controller associated with a display device can be configured to correct for output white point shift due to variation, across separate color subfields of an image frame, in the respective number of subframes or the respective subframe weights. The controller can determine aggregate subframe weights for at least two color subfields and adjust at least one display parameter based on the determined aggregate subframe weights, to shift the output white point towards a white point of a target color gamut. The display parameter(s) can include a duty cycle of a color subfield, tristimulus coordinates of light used to illuminate a color subfield or gamut mapping function. The controller can display the image frame according to the adjusted display parameter(s).

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: This disclosure provides systems, methods and apparatus for optically obstructing inoperable display elements in a display apparatus. In one aspect, a display apparatus can include a plurality of display elements each having a shutter suspended over a substrate. The shutters can be capable of moving into and out of an optical path aligned with at least one aperture formed in a substrate. When a display element is inoperable, the shutter associated with the display element may be unable to block light passing through the aperture. To improve the quality of images formed on the display apparatus, the aperture associated with the inoperable display element can be optically obstructed, so that light directed toward the aperture is blocked even if the shutter is stuck in the open position. In some implementations, the aperture may be optically obstructed by a light-blocking pigment deposited over the aperture.

Abstract: This disclosure provides systems, methods and apparatus for powering display light sources. A display can include a DC/DC converter included in a power management integrated circuit (PMIC) to serve as the light source driver. Battery current drawn by the DC/DC converter can be smoothed, in part, by introducing a capacitor in parallel with the set of light sources. A display controller can control the DC/DC converter to output a substantially constant current for substantially the entirety of a time period for displaying a set of subframes, storing enough charge on the capacitor to support the current drawn through the light sources by a digital-to-analog converter included in the PMIC. Output current level for the DC/DC converter can be determined for the time period over which the subframes are displayed. The set of subframes can include subframes of a single image frame, or of one or more image frames.
