ABSTRACT:
Display structures and methods are provided that introduce redundancy and use this redundancy with different mapping rules on different interleaved display lines to visually diffuse display artifacts. The artifacts are typically produced by errors in the transmission and recovery of analog display signals that subsequently drive digital displays. This visual diffusion substantially reduces the display artifacts and, because these visual improvements require only one element (an ADC) in the display system to be configured at a higher resolution, the visual advantageous are realized with relatively low cost.
