    摘要: A method for printing or exposing photosensitive media is disclosed herein. The method uses standard spatial light modulators with standard addressing circuitry. The data is written to the device for the first row, the photosensitive media is exposed to the light reflected from the device, and the device is turned off. The data from the first row is then written to the second line of the device, and new data is loaded into the first line of the device. The media is again exposed. This is repeated until the entire region of the drum is completely exposed. The device can be repositioned to cover a different region of the drum and the process would be repeated.

    摘要: A spatial light modulator array with adaptable multiplexed memory architecture. The modulator has an array of individually controllable pixels, where a predetermined number of pixels are assigned to a memory cell (16). The memory cell receives data from an input bus (14). On a signal (22), the memory cell transfers its data to a secondary memory (18), and to the activation circuitry (20) of one of its assigned pixels. On a second signal, the pixel responds to the data on the activation circuitry. When the display time of the data is less than the load time for the memory cell, the secondary memory is set with a second signal (24) so as to make the pixel dark and another control signal makes the pixels respond to the memory. In this way, the load time is lengthened and the data rate remains relatively low, even though the number of bits of intensity may not be the same as the number of bits of intensity used to determine the number of pixels assigned to each memory cell.

    摘要: A method and system for adjusting the brightness and contrast of a digital pulse-width modulated display without scaling the input image data. Brightness is adjusted by changing the duty cycle of a displayed pixel either by altering the bit display durations, or by turning the pixel on during blanking periods 36. The contrast ratio may be altered by changing the display duration of at least one of the MSBs differently than the display duration of at least one of the LSBs. Contrast may be increased by extending the MSB display periods 50 and shortening the LSB display periods 52. Contrast may be decreased by shortening the MSB display periods 56 and extending the LSB display periods 58. The color tint of the displayed image may be altered by individually changing the brightness of the constituent colors.

    摘要: An SLM-based video receiver (10) receives a video input of some standardized format at a signal interface unit (11) and passes the input to a processor (12). The processor (12) performs analog-to-digital conversion if the pixel data is analog and also performs other enhancements to prepare the pixel data for loading into a video memory (14). The pixel data from the processor (12), representing a field of pixel data, is stored into the memory (14) for loading into rows of pixel elements of a spatial light modulator (16). The spatial light modulator (16) receives the pixel data in rows and each individual pixel element responds accordingly. The pixel elements of the spatial light modulator (16) emit light or reflect light from a source (18) and generate a video frame for display on a screen (20). By exploiting the addressing functions of the spatial light modulator (16), the SLM-based video receiver (10) displays a video frame using a field of pixel data.
