    Abstract: Systems and methods for a digital pixel circuit for liquid crystal displays are provided. The design includes a dual-voltage pixel design, a two-transistor level-shift circuit design, self-adjusting transistor bias circuitry; and an optional on-chip test-array to determine die-specific design-center values for critical transistor leakage and threshold parameters. Level shift design simplicity, small pixel pitch, and applicability for small display applications such as microdisplays, are among the various benefits and advantages obtained.

    Abstract: An image system dynamically updates drive sequences in an image system. Drive sequences are image display settings or display driving characteristics with which a display is operated. The image system may determine the drive sequence at least partially based on input from one or more sensors. For example, the image system may include sensors such as an inertial measurement unit, a light sensor, a camera, a temperature sensor, or other sensors from which sensor data may be collected. The image system may analyze the sensor data to calculate drive sequence settings or to select a drive sequence from a number of predetermined drive sequences. Displaying image content on a display includes providing the display with image data and includes operating the display with various drive sequences.

    Abstract: A method is disclosed for controlling a liquid crystal pulse width modulated display. A repetition period includes A group periods, each including B modulation intervals, each modulation interval spanning H unit durations and, except for the final modulation interval of the repetition period, a remainder unit duration. A desired number N of unit duration pulses are distributed into H unit duration pulses for each modulation interval, with remainder desired pulses distributed among the remainder unit durations of the modulation intervals. A drive sequence is generated, including one or more repetitions of the repetition period.

    Abstract: A display driver device (210) receives a downloadable “sequence” for dynamically reconfiguring displayed image characteristics in an image system. The display driver device comprises one or more storage devices, for example, memory devices, for storing image data (218) and portions of drive sequences (219) that are downloaded and/or updated in real time depending on various inputs (214).
