Cascaded bit sequences in display systems

摘要

The present disclosure pertains to a method for designing cascaded bit sequences for cascaded digital displays. The method avoids unwanted interactions between cascaded sequences in cascaded digital displays. By using sequences with a particular structure, cascaded sequences can be designed such that no sequence is affected by the others. The following rules must be followed in constructing the sequence. First, the display devices must be frame-locked, so that the timing relationship between the sequences is maintained throughout each frame. Second, for each display device, the ratio of bit plane weights must remain constant, regardless of the pixel data displayed on the other display device(s). Third, the amount of bit plane skew must remain constant, regardless of the pixel data displayed on the other display device(s). Fourth, bit plane phased leakage must be compensated for or avoided.

1. A method for designing and using cascaded bit sequences for a cascaded display system comprising a plurality of cascaded display devices and producing one or more images, comprising:
constructing cascaded bit sequences for the one or more images, wherein the cascaded bit sequences are constructed of segments and bits so that
(a) the cascaded display devices utilize frames that are locked, wherein timing between the cascaded bit sequences is maintained throughout each frame of each cascaded display device,(b) for each cascaded display device, a ratio of bit plane weights remains constant,(c) bit plane skew remains constant,(d) bit plane phased leakage is avoided, and(e) the cascaded bit sequences are constructed to include short bits without including additional dark time; and implementing the cascaded bit sequences on the cascaded display system to produce a desired multiplication of intensities of the one or more images, wherein the cascaded bit sequences for each cascaded display device do not otherwise interact with or affect each other.
