摘要： A method displays a halftone image on a display unit by using a frame division technique that divides each frame of the halftone image into subframes each having a specific sustain discharge period to provide a specific intensity level. The method differs the position of the halftone image on the display unit from subframe to subframe in each frame. The method is capable of displaying dynamic halftone images without intensity level disturbance, smears, or false color contours.
