Abstract
In a display apparatus having a plurality of light emitting elements, a single frame includes a plurality of sub-frames, each of which includes a plurality of weighted elements with different gradations expressed at powers of two. When the number of sub-frames in a single frame is X (X is an integer greater than 1) and a maximum gradation value that can be expressed in each of the sub-frames is 2−1 (Y is an integer greater than 1), and the single frame is expressed by the gradation value in a range of X·2to X(2−1)−2, a lighting controller allocates the gradation value to each of the sub-frames so that the weighted element at an end of a timeline of at least one sub-frame of the plurality of sub-frames in the single frame is turned OFF.
