Abstract
A display apparatus has code conversion assembly for converting a video signal into a coded signal comprised of a plurality of bits, each indicating a combination of luminescence and non-luminescence in the plurality of sub-fields. The plurality of sub-fields includes at least one sub-field having a relative ratio of luminescent time which deviates from a power series of 2. The plurality of sub-fields having a high relative ratio of luminescent time are arranged in a time sequence in a descending or ascending order. The relative ratio of luminescent time includes at least the highest, the second highest and the third highest relative ratios of luminescent time. When an up-shift occurs in a circumstance that at a gray level of n, a first sub-field having the high relative ratio of luminescent time is lit on while a second sub-field having a next higher relative ratio of luminescent time than the first sub-field is lit off, and at a gray level of n+1, the second sub-field is lit on, the first sub-field is caused to be lit off at the gray level of n+1.
