A method for driving a display apparatus has a predetermined plural number of light emission blocks (SF0 to SF6) in each field (ODD FIELD;EVEN FIELD;FRAME), and displays grayscale by combining the light emission blocks (SF0 to SF6). When the total number of light emission pulses is varied by a power control, the ratio of emission pulses set for each subfield is displaced from the theoretical value, resulting in a loss of continuity. A grayscale level addition/subtraction operation is performed, by computation, on a discontinuous grayscale in accordance with an input grayscale level. Alternatively the grayscale level addition/subtraction operation is performed, on a discontinuous grayscale, in accordance with an input grayscale level, before applying error diffusion, for any brightness discontinuous portion occurring due to the combination of the light emission blocks (SF0 to SF6). |
