When moving images are displayed on matrix display panels, we sometimes observe pixels that appear at places where they should not. For instance, red pixels appear at the places of green or blue pixels, or even at places between two pixels. We named this phenomenon "false pixels". These false pixels are found to be originated from the after-image of human eyes and stimulation pattern from light-emitting pixels. Also, when the displays have extended light-emission periods, we observe extension of apparent pixel size. Because of these phenomenon, quality degradation occurs to moving images in the matrix displays.
