摘要： A gamma variation of image intensity is created by varying the illumination intensity during a pulse width modulated display time period. During the pulse width modulated display time period a ramp signal may be compared with the image data to determine when pixel electrodes of the pixel array are switched. The illumination intensity may be varied in concert with ramp signal to produce a quadratic variation of displayed intensity on image data value. The illumination source could be an LED illumination source and intensity of the LED illumination source could be controlled using pulse width modulation.

摘要： A digital display provides pulse-width-modulated pixel waveforms by applying a wired-NOR function to selected bits of stored image data. Image bits are selected according to a digital sequence and the wired-NOR function results in a trigger signal that may be used to switch the state of a pixel element. The pixel element may be a pixel state latch of a pixel driver circuit. The digital display may accept conventional 24-bit color video signals (one 8-bit gray-scale value for each pixel for each of the red, green, and blue primary colors), and convert this input signal to sequential color with PWM digital gray scale drive to each pixel.

摘要： A digital display with image data storage memory that minimizes the impact of defective memory cells by remapping stored image data. Memory defects may be detected by automatic or visual testing. The digital display may perform a mapping process such that image data placed in the location of the defective storage cells is based on the significance of the data, both by bit and by color. The mapping process may operate on addressed rows of memory cells of the digital display.

摘要： A microdisplay having interface circuitry on the same silicon backplane to allow it to receive digital images and video in a variety of formats and convert same to field sequential color signals for generation of full color images. It includes column data processors having a comparator for each block of N-columns of pixels. Image data is double-buffered in SRAM memory cells located beneath the pixel electrodes, but not within each pixel. The stored data is logically associated with each pixel via the column data processors. Image compression is accomplished by converting RGB data to a variant of YUV data and sampling the color components of the converted data less frequently than the luminance components. The SRAM image buffer consumes a reduced amount of power. A temperature compensation scheme allows the temperature of the microdisplay to be sensed and the drive voltage to the pixel electrodes to be varied in response thereto.

摘要： 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.

摘要： Drive voltages of a liquid crystal display are adjusted based on one or more environmental conditions. The pixel drive voltages may be adjusted based on temperature. A pixel voltage may be varied such that it is a higher voltage at relatively lower temperatures and a lower voltage at relatively higher temperatures. The window voltage may be varied based on temperature. The window voltage may be stepped through different values within a display phase. The window voltage may be varied during a blanking period of the display phase such that the pixel sees a relatively larger voltage to obtain a desired initial state more quickly. Then, during a light modulating time period, the window voltage may be stepped such that there is a lower voltage field for holding the state of the pixel.

摘要： A display system that achieves a gamma characteristic different than 1, such as a gamma characteristic of 2 for example. The gamma characteristic may be selectable and it may be selectable via timing characteristics rather than by varying the intensity of the light source. Defective memory registers are also compensated for by selecting them to store bits of relatively lower significance.

摘要： 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.
