IN-FRAME TIME-SHARING TYPE HALF-TONE DISPLAY METHOD AND IN-FRAME TIME-SHARING DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress a color false outline phenomenon when a dynamic image is displayed by means of an in-frame time-sharing type half-tone display method. SOLUTION: In the half-tone display method in a display method in which a display screen is constructed of a plurality of cells, data displayed in each cell is rewritten for every frame, and luminance of each cell is decided on the basis of a light quantity radiated from the cell during one frame equivalent duration, one frame is divided into a plurality of subframes, and a subframe radiating light and a subframe radiating no light are combined together so as to indicate a half tone. In this case, the subframes whose luminances satisfy a relationship Nn=Nn-1+Nn-2 are provided when luminances of a plurality of the subframes are Nn, Nn-1, Nn-2,..., N1 in the luminance order from the most intensity one.
