Patent ID: 6903710

Claim:
A method of displaying a halftone image on a display panel by dividing one frame of the halftone image into a plurality of subframes each having a specific sustain discharge period to provide a specific intensity level, light emission of each subframe being controlled such that luminance of a pixel on a retina becomes substantially equal to the luminance of a pixel corresponding to an input image based on a move direction and a speed of motion of the input image that moves on the display panel, comprising the steps of: preparing at least two subframes having the same intensity level in the plurality of subframes, where one halftone image is represented by at least two patterns of light-emitting subframes; determining one pattern of light-emitting subframes by selecting subframes located close to a portion of a specific pixel on the retina; and controlling light emission of subframes in the determined one pattern based on positioning information of the subframes in the specific pixel on the retina, with priority, when the at least two subframes having the same intensity level are included in an area of the specific pixel on the retina.
