Abstract
A display device includes an auto current limiter (ACL) circuit and a luminance control circuit. The ACL circuit acquires a first parameter on the basis of luminance-related data of input image data, and then acquires a second parameter by applying a luminance control parameter from the luminance control circuit to the first parameter. The ACL circuit corrects the input image data by a second correction function acquired from the second parameter.
Claims5
A display device comprising:
- a display panel;
- a gray-level correction circuit;
- and
- a luminance control circuit which controls luminance of the display panel, wherein
- the gray-level correction circuit
- acquires a first parameter for generating a first correction function on the basis of luminance-related data of input image data, and
- corrects the first parameter on the basis of a luminance control parameter related to control of the luminance of the display panel from the luminance control circuit, acquires a second parameter for generating a second correction function, and corrects a gray level of the input image data on the basis of the second correction function.
