Abstract

The present disclosure provides a display device with a display panel and driver. The driver includes a logo compensator to generate a logo map data with respect to a logo area through which the logo image is displayed and compensates for a brightness of the logo area using the logo map data. The logo compensator includes an extractor, a logo calculator, a logo determination unit, and a brightness compensation block. The extractor extracts logo area data. The logo calculator calculates the logo map data with first data corresponding to a first image recognized as the logo image and second data corresponding to a second image recognized as a logo background image. The logo determination unit sets a boundary area and determining whether a first area corresponding to the first image overlaps the boundary area to output determination data. The brightness compensation block compensates for the brightness of the logo area.

Dependent claims

A display device comprising:

a display panel comprising a display area configured to display an image comprising a logo image and a non-logo image;
and
a driver configured to receive an image signal and apply a data signal to the display panel, the driver comprising a logo compensator configured to generate logo map data for a logo area configured to display the logo image and to compensate for a brightness of the logo area based on the logo map data, the logo compensator comprising:
an extractor configured to extract logo area data with respect to the logo area from the image signal;
a logo calculator configured to calculate the logo map data comprising first data corresponding to a first image recognized as the logo image and second data corresponding to a second image recognized as a logo background image around the logo image;
a logo determination unit configured to set a portion of the logo area as a boundary area, to determine whether a first area corresponding to the first image in the logo area overlaps the boundary area, and to output determination data;
and
a brightness compensation block configured to compensate for the brightness of the logo area based on the determination data.
