Abstract:
A first latch circuit temporarily memorizes a display pixel data by one line. A second latch circuit temporarily memorizes the display pixel data as a preceding display pixel data that precedes the display pixel data by one line. The load judging circuit judges a transition state of the display pixel data based on the display pixel data and the preceding display pixel data and predicts a drive load capacity CL based on a result of the judgment. A drivability adjusting circuit adjusts a signal level of the display pixel data based on a result of the prediction of the drive load capacity CL and adjusts drivability of an output.
