Abstract
An image display apparatus include a plurality of scan wirings and a plurality of modulation wirings forming a matrix, display elements to be driven in matrix according to a scan signal applied by the scan wirings and a modulation signal applied by the modulation wirings, and a scan circuit for scanning the plurality of scan wirings and applying a scan signal to the selected scan wiring. An output circuit stores an input signal to be inputted in time-series, generates a plurality of outputs consisting of a time-series signal for generating a modulation signal based on the stored result and outputs the plurality of outputs to a plurality of output paths as parallel outputs. In addition, a modulation side drive circuit outputs parallel modulation signals based on the time-series signal for generating a modulation signal. The modulation side drive circuit is provided in a plural form corresponding to each of the plurality of output paths and each of the plurality of modulation side drive circuits supplies the modulation signal to a part of and a plurality of modulation wirings among the plurality of modulation wirings, and the output circuit starts to output at least one of the parall…
