Abstract
The color patterned front light (CPFL) may be implemented by shining light through a side of a CPFL panel that is situated adjacent to and in front of a monochromic reflective display (MRD). The CPFL may direct one of red, green, blue, or white light through a rear surface of the panel and onto each of the pixels in the MRD. The pixels may be grouped in blocks, such as n-by-m or n-by-n blocks of pixels. The pixels in the block may be selectively activated by the MRD to either absorb the light or reflect the light shone on the respective pixel. By adjusting the representation of the pixels in the MRD, the block may appear to change color based on the colored light from the CPFL that is reflected outward from the display.
