    摘要： This disclosure provides systems, methods, and apparatus for providing pixel circuits for controlling the state of operation of light modulators in a display device. The state of operation of the light modulator can be controlled by the pixel circuit based on a data voltage stored in a data storage element of the pixel circuit. The pixel circuit includes an actuation circuit for providing an actuation voltage to the light modulator and a feedback circuit for providing a positive feedback voltage from an output node of the actuation circuit to an input node of the actuation circuit. In some implementations, the feedback circuit includes the data storage element connected between the input node and the output node.

    摘要： 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.

    摘要： This disclosure provides systems, methods and apparatus for a multi-state shutter assembly. The multi-state shutter assembly can be used in an electronic display. The shutter assembly can include a movable light obstructing component. The shutter assembly also can include first and second actuators configured to move the light obstructing component between three states, including a fully light obstructive state, a substantially transmissive state, and a partially transmissive state. At least one of the three states is a neutral state in which both the first and second actuators are in an unactuated state. The shutter assembly also can include a controller configured to control the first and second actuator to selectively move the light obstructing component into each of the three states.

    摘要： This disclosure provides systems, methods and apparatus for providing multi-level multi-state shutter assemblies. The shutter assembly includes at least a first shutter at a first height over a substrate and a second shutter at a second height over the substrate. Both the first shutter and the second shutter can be operated in an open or closed state for passing or partially blocking light propagating through an aperture. In some implementations, the shutter assembly can operate in four states: a fully transmissive state, a fully obstructive state and two partially transmissive states based on the open or closed states of the first and second shutters.
