Abstract: A method of increasing the brightness of a pulse width modulation display system. Image bits are displayed during display periods having a non-binary relationship. The display period of an object bit 902 is set equal to a minimum data load time, and the display periods of all other bits are initially set to have a binary relationship with the object bit. The display periods of at least one non-object bit 904, 906, 908 are then reduced in order to reduce the total frame time to no more than the available useable frame time 910. Preferably, only the display periods of bit of significance greater than the object bit are reduced. The reduction of display periods is guided by Weber's law, in order to prevent the non-binary steps from being noticeable or objectionable to the viewer.

Abstract: The present invention provides a method of ameliorating the effects of misalignment between modulator arrays, and a system using the same. The ability reduce the effects of misalignment allows multiple, smaller, more cost effective arrays to be used instead of one large array. This can reduce the manufacturing costs of the array, especially arrays that are produced using semiconductor manufacturing processes such as the digital micromirror device. To avoid visual artifacts caused by the misalignment of two or more modulator arrays 1702, 1704, the individual arrays are overlapped and the portion of the image is generated by both arrays. The contribution to the combined output by the overlapping arrays varies, with each array making a small contribution to the overlapped area 1706 at one end and a large contribution at the other end of the overlapped area 1706. Because the overlapping portions of the modulator arrays 1712 collectively form a portion of the image, the alignment error is effectively spread over the entire overlapping portion 1706 and is much less noticeable.

Abstract: A method of pulse width modulation using a spatial light modulator (40) with a finite transition time. The method uses m bits per sample to digitize the incoming data, but apportions the LSB times for pulse width modulation based upon m-1 bits. The current video frame displays all of the bits for each sample, except for the LSBs for each sample. The next video frame displays all of the bits for each sample, adding one more LSB for dividing up the frame time. The first frame could use either the additional LSB time and display no data, or it could use only that number of LSB times it needs. In the latter, the system will have to adjust to different partitions of the frame time for alternating frames. The system includes a spatial light modulator (40), a memory (42), a formatter (48), a sequence controller (44) and a toggle circuit (46), to perform this method.

Abstract: 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. Two such light functions can be subtracted to compare two different patterns on the same display element (interframe) or to compare the same pattern on different display elements (intraframe). The result of the subtraction is a light difference function, which can be expressed as a series function. Mathematical expressions using the series function correlate to various optical characteristics.
