Abstract
A display device includes a display panel including a display region and first and second drivers. Feature data indicating feature values of first and second images displayed on first and second portions of the display region are exchanged between the first and second drivers, and the first and second drivers drive the first and second portions of the display region in response to the feature data.
Claims20
A display device, comprising:
- a display panel;
- a plurality of drivers driving said display panel;
- and
- a processor,
- wherein said plurality of drivers include:
- a first driver driving a first portion of a display region of said display panel;
- and
- a second driver driving a second portion of said display region,
- wherein said processor supplies first input image data associated with a first image displayed on said first portion of said display region and supplies second input image data associated with a second image displayed on said second portion of said display region,
- wherein said first driver is configured to calculate first feature data indicating a feature value of said first image from said first input image data,
- wherein said second driver is configured to calculate second feature data indicating a feature value of said second image from said second input image data,
- wherein said first driver is configured to calculate first full-screen feature data indicating a feature value of an entire image displayed on said display region of said display panel, based on said first and second feature data, to generate first output image data by performing a correction calculation on said first input image data in response to said first full-screen feature data, and to drive said first portion of said display region in response to said first output image data, and
- wherein said second driver is configured to generate second output image data by performing the same correction calculation as that performed in said first driver on said second input image data and to drive said second portion of said display region in response to said second output image data.

A display panel driver for driving a first portion of a display region of a display panel, comprising:
- a feature data calculation circuit receiving input image data associated with a first image displayed on said first portion of said display region and calculating first feature data indicating a feature value of said first image from said input image data;
- a communication circuit receiving from another driver second feature data indicating a feature value of a second image displayed on a second portion of said display region driven by said other driver;
- a full-screen feature data operation circuit calculating full-screen feature data indicating a feature value of an entire image displayed on said display region of said display panel, based on said first and second feature data;
- a correction circuit generating output image data by performing a correction calculation on said input image data in response to said full-screen feature data;
- and
- a drive circuitry driving said first portion of said display region in response to said output image data.

An operation method of a display device including a display panel and a plurality of drivers driving said display panel, said plurality of drivers comprising a first driver driving a first portion of a display region of said display panel and a second driver driving a second portion of said display region, said method comprising:
- supplying first input image data associated with a first image displayed on said first portion of said display region to said first driver;
- supplying second input image data associated with a second image displayed on said second portion of said display region to said second driver;
- calculating first feature data indicating a feature value of said first image from said first input image data in said first driver;
- calculating second feature data indicating a feature value of said second image from said second input image data in said second driver;
- transmitting said second feature data from said second driver to said first driver;
- calculating first full-screen feature data indicating a feature value of an entire image displayed on said display region of said display panel, based on said first and second feature data in said first driver;
- generating first output image data by performing a correction calculation on said first input image data, based on first full-screen feature data in said first driver;
- driving said first portion of said display region in response to said first output image data;
- generating second output image data by performing the same correction calculation as that performed in said first driver on said second input image data in said second driver;
- and
- driving said second portion of said display region in response to said second output image data.
