A method of implementing pulse-width modulated image display systems (10, 20) with a spatial light modulator (SLM) (15) configured for split-reset addressing. Display frame periods are divided into time slices. Each frame of data is divided into bit-planes, each bit-plane having one bit of data for ...

A DMD spatial light modulator (20) having an improved reset waveform (80) that improves the electrostatic control over the DMD mirrors (30) during switching states (T3). An intermediate bias level is provided to the yoke (32) and mirror (30) during the mirror reset cycle (T3) which is sufficient to ...

Texas Instruments Incorporated, Charles A Brill, Frederick J Telecky Jr, Richard L Donaldson, November 16, 1999: US05986721 (14 worldwide citation)

A method of controlling the display period of video data, and system thereof, that matches the frame period of displayed video data to the speed of a color wheel. The period of the color wheel is measured to determine the display period. An optimum frame sequence pattern is selected, based on the di ...

Mark L Burton, Donald B Doherty: Reset scheme for spatial light modulators. Texas Instruments Incorporated, Julie L Reed, James C Kesterson, Richard L Donaldson, June 9, 1998: US05764208 (7 worldwide citation)

A method for causing a micromechanical spatial light modulator to display data for a period less than its settling time. The modulator elements receive a first pulse (40) that causes them to release from their previous state, a bias voltage is removed and reapplied, allowing the elements to move to ...

A method of evaluating pulse width modulation patterns for a spatial light modulator display device. The method makes use of a light difference series function. This series function is obtained by representing on or off times of a display element as a light function. (FIG. 3). Two such light functio ...
