Please note that as the frame number progresses, the bit pattern in each row moves to the
right one pixel. This type of pattern shown in an area may cause diagonal lines to appear as
though they are moving to the right. As previously stated, any image distortion greatly
depends on the application. However, the pattern shown in
tendency to demonstrate a walking distortion.
Assuming that the 3-bit input pattern that represents this 33% duty cycle grayscale is 0x2 (or
010b), the values in
table. In this mode, the X locations are ignored by the grayscale generation.
Finally, just for demonstration purposes, a matrix with mixed 3 and 4 count axes is shown in
