Light emission control method capable of alleviating high contrast coupling

A light emission control method to be implemented by a driver circuit and for controlling a display, the display including a plurality of light emitting elements that are to be divided into a plurality of display sets, said light emission control method comprising steps of:

• (A) generating a number (M) of sub-frames based on an image frame, where
• M=2B+C=(N+E)+C, in which B>0, N>0, E≥0, and C≥0,
• the image frame corresponds to a display time period, and contains frame gray values of the plurality of light emitting elements,
• the display time period includes a number (M) of display time intervals,
• each of the number (M) of sub-frames contains partial gray values of the plurality of light emitting elements, and
• with respect to each of the plurality of light emitting elements, the partial gray value of the light emitting element that is contained in each of a first one to an Nth one of the number (M) of sub-frames is greater than or equal to zero, and a sum of the partial gray values of the light emitting element that are respectively contained in the first one to the Nth one of the number (M) of sub-frames is equal to the frame gray value of the light emitting element;
• (B) obtaining a display set arrangement that indicates which one(s) of the plurality of light emitting elements is/are included in each of the plurality of display sets;
• (C) obtaining a display order of the number (M) of sub-frames in the number (M) of display time intervals, where
• the display order indicates, with respect to each of the plurality of display sets, a one-to-one corresponding relationship between the number (M) of sub-frames and the number (M) of display time intervals, and
• the one-to-one corresponding relationships indicated by the display order with respect to the plurality of display sets are different from each other;
• and
• (D) in each of the number (M) of display time intervals, controlling each of the plurality of display sets as indicated by the display set arrangement to display one of the number (M) of sub-frames that corresponds to the display time interval according to the one-to-one corresponding relationship indicated by the display order with respect to the display set.
