Abstract:
A display apparatus includes a display panel; a correcting circuit configured to carry out gamma correction on input gradation data in response to correction data which specifies a shape of a gamma curve to generate output gradation data; and a driving circuit configured to drive the display panel in response to the output gradation data from the correcting circuit. The correcting circuit carries out approximation calculation for the gamma correction based on the input gradation data by using a correction calculation equation whose coefficients are determined based on the correction data, and the correction calculation equation is switched based on a value of the input gradation data and a value of the correction data.
