Abstract
A display panel driver includes a reference register, a calculator, and a data signal generator. The reference register stores a reference compensation gamma data curve generated by compensating a luminance characteristic deviation of a display panel in a reference luminance mode. The calculator calculates a compensation gamma data curve for each of a plurality of luminance modes based on the reference compensation gamma data curve to perform a dimming operation. The data signal generator generates data signals corresponding to input grayscale levels based on the compensation gamma data curve.
Claims20
A display panel driver, comprising:
- a reference register to store a reference compensation gamma data curve, the reference compensation gamma data curve to be generated by compensating a luminance characteristic deviation of a display panel in a reference luminance mode;
- a calculator to calculate a compensation gamma data curve for each of a plurality of luminance modes based on the reference compensation gamma data curve to perform a dimming operation;
- and
- a data signal generator to generate data signals corresponding to input grayscale levels based on the compensation gamma data curve.
A display device, comprising:
- a display panel including a plurality of pixels;
- and
- a display panel driver to drive the display panel, wherein the display panel driver includes:
- a reference register to store a reference compensation gamma data curve, the reference compensation gamma data curve to be generated by compensating a luminance characteristic deviation of a display panel in a reference luminance mode;
- a calculator to calculate a compensation gamma data curve for each luminance mode based on the reference compensation gamma data curve to perform a dimming operation;
- and
- a data signal generator to generate data signals corresponding to input grayscale levels based on the compensation gamma data curve.
