A write buffer configured to receive the bit plane blocks of data and to generate bit plane data frames. A memory controller configured to receive the bit plane data frames and to write a first bit plane data frame to a memory while simultaneously reading a second bit plane data frame from memory. A read buffer configured to receive the second bit plane data frame and to convert the second bit plane data frame to a digital display device format.

Abstract: 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.

Abstract: Independent color stretch is an improved method for “stretching” the color sequence utilized in color-sequential displays using switchable light sources, such as LED or Laser, to match the frame rate of the video source. It utilizes a stretch factor that is directly proportional to the sequence duration to simplify the calculation of stretch factors and allow them to be combined. Independent color stretch also provides independent stretch factors for each color and allows real-time adjustment of the duty cycle of each color.
