ABSTRACT:
A method for driving a display apparatus has a predetermined plural number of light emission blocks in each field, and displays grayscale by combining the light emission blocks. A grayscale level addition/subtraction operation is performed, by computation, on a discontinuous grayscale in accordance with an input grayscale level or 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.
