Abstract
A circuit apparatus is provided for driving source electrodes of a display panel based on image data and to control a backlight of the display panel. For example, the circuit apparatus includes a display drive (DD) circuit having a parameter generation (PG) part and an image data conversion (IDC) part. The PG part is operable to generate an image data-conversion parameter and a backlight control parameter based on a brightness distribution of the image data of one frame. The IDC part is operable to convert the image data based on the image data-conversion parameter. The DD circuit is operable to output source signals generated based on the converted image data and output, control the backlight based on the backlight control parameter, and stop an action of the parameter generation part in response to no change in the image data of one frame from image data of a preceding frame being detected.
