    Abstract: A display device includes a driver for a display panel. The display panel includes a first area and a second area that includes a plurality of pixels. The driver includes a master driver and a slave driver. The master driver compensates a first image signal for the first area to generate a first compensation signal based on the first image signal and a second image signal for the second area. A first data signal corresponding to the first compensation signal and a scan control signal a provided to the first area. The slave driver compensates the second image signal to generate a second compensation signal based on the first image signal and the second image signal. A second data signal corresponding to the second compensation signal and the scan control signal are provided to the second area.

    Abstract: A pixel luminance compensating unit is disclosed. In one aspect, the disclosed pixel luminance compensating unit includes an uncompensated gray-level region processing unit configured to generate first output-data by processing first input-data corresponding to a first portion of an input luminance curve corresponding to an uncompensated gray-level region. The disclosed unit further includes a compensated gray-level region processing unit configured to generate second output-data by processing second input-data corresponding to a second portion of the input luminance curve corresponding to a compensated gray-level region. The disclosed unit further includes an interpolated gray-level region processing unit configured to generate third output-data by processing third input-data corresponding to a third portion of the input luminance curve corresponding to an interpolated gray-level region, wherein the interpolated gray-level region processing unit is configured to generate the third portion by interpolating between the first portion and the second portion.
