Patent ID: 7940231

Claim:
A display panel drive-control device comprising: a first latch circuit for temporarily memorizing a display pixel data by one line; a second latch circuit for temporarily memorizing a preceding display pixel data that precedes the display pixel data by one line; a load judging circuit for judging a transition state of the display pixel data based on the display pixel data and the preceding display pixel data and predicting a drive load capacity based on a result of the judgment; a drivability adjusting circuit for adjusting a signal level of the display pixel data based on a result of the prediction of the drive load capacity; wherein the drivability adjusting circuit comprises: a signal level adjusting circuit for adjusting the display pixel data to have such a signal level that is necessary for the display; and a drivability adjustment output circuit for adjusting a drivability of the display pixel data which is level-adjusted with the signal level adjusting circuit in accordance with a prediction result of the drive load capacity by the load judging circuit, and wherein the drivability adjusting circuit comprises: a plurality of drivability adjustment output circuits having different levels of drivability respectively; and a selector for selecting the drivability adjustment output circuit suitable for the drive load capacity from the plurality of drivability adjustment output circuits.
