A multi-state light modulating system having grayscale based on a series of time intervals includes an arrangement that establishes the duration of each time interval such that the time intervals in the series have progressively varying duration. The arrangement also determines a drive signal for each time interval that causes the light modulator to assume a specific light modulating state. The arrangement also causes the light modulator to produce a desired time-averaged light level over the series of time intervals by in part driving the light modulator using the drive signal that corresponds to a particular time interval for a duration that is longer than the duration of the time interval. The arrangement also or alternatively arranges the series of time intervals such that the light modulator is in the same state immediately prior to the particular time interval as the light modulator is in immediately after the time interval.

A display system includes a light modulator divided into an array of individually controllable pixels and an input-driven illumination device. The illumination device is adapted to receive a variable input and is configured to direct light of variable intensity onto the modulator, depending on the input. The display system further includes a calibrating arrangement for establishing the input to the illumination device to produce a desired intensity level of light. The calibrating arrangement includes a light sensing mechanism, which senses the light from the illumination device while the illumination device is driven by an initial input. The calibration arrangement is configured to determine a comparison between the sensed light and a value representative of the desired-intensity level. The calibration arrangement further includes a control arrangement responsive to the comparison for varying the input so as to provide light of the desired intensity level.

A direct-view display includes an array of MEMS light modulators and a control matrix formed on a transparent substrate, where each light modulator can be driven into at least two states, and a controller for controlling the states of each light modulator in the array. The control matrix transmits data and actuation voltages to the array. The controller includes an input, a processor, a memory, and an output. The input receives image data encoding an image frame for display. The processor derives a plurality of sub-frame data sets from the image data, where each sub-frame data set indicates desired states of light modulators in multiple rows and multiple columns of the array. The memory stores the plurality of sub-frame data sets. The output outputs the plurality of sub-frame data sets according to an output sequence to drive light modulators into the states indicated in the sub-frame data sets.

Methods and devices for generating grayscale using digital pulse width modulation between optical states. Grayscale may be generated for each component color using multiple algorithm cycles per display field. Subsets of binary weighted bit values for data values of each component color may be split across algorithm cycles to reduce the number of data comparisons per color per display field. The total number of data comparisons per color per display field may be reduced by half or more.

A display system includes a display panel having an array of pixels, the pixels having ON states and OFF states. The pixels form images by modulating light in a temporal sequence during an image frame in response to drive signals generated from incoming video data. A light source arrangement that emits at least two colors of light illuminates the display panel. The image frame is divided into color segments with only one color of light being emitted from the light source during each segment. The color segments are further divided into grayscale periods. Transition segments are provided for the transitions between colors. The state of each pixel during these transition segments is a function of the desired brightness level for each pixel, as derived from incoming video data.

A display device adjusts the operational timing of the illumination source relative to pixels of the display device. Grayscale may be generated in the pixels using pulse width modulation. The operational timing may be adjusted based on the temperature of the display device. The display device may be a liquid crystal display device and the operational timing of the illumination source may be adjusted to compensate for variation in the response time of the liquid crystal material based on temperature.
