Abstract
A mura compensation device includes a first memory which stores a grayscale compensation value of a reference pixel defined by m×n pixels included in a display panel, and a weight, where each of m and n is a positive integer equal to or greater than 2, a second memory which receives the grayscale compensation value from the first memory and stores the grayscale compensation value, and a compensator which applies the grayscale compensation value and the weight to grayscale data to generate compensated grayscale data. The compensator applies an individual weight to the weight depending on a normal state or defective states of the display panel to adjust the weight.

A mura compensation device comprising:
- a first memory which stores a grayscale compensation value of a reference pixel defined by m×n pixels included in a display panel, and a weight, wherein each of m and n is a positive integer equal to or greater than 2;
- a second memory which receives the grayscale compensation value from the first memory and stores the grayscale compensation value;
- and
- a compensator which applies the grayscale compensation value and the weight to grayscale data to generate compensated grayscale data,
- wherein the compensator applies an individual weight to the weight depending on a normal state or defective states of the display panel to adjust the weight.
A mura compensation system comprising:
- a first memory which stores a grayscale compensation value of a reference pixel defined by m×n pixels included in a display panel, and a weight, wherein each of m and n is a positive integer equal to or greater than 2;
- a second memory which receives the grayscale compensation value from the first memory and stores the grayscale compensation value;
- a compensator which applies the grayscale compensation value and the weight to grayscale data to generate compensated grayscale data;
- and
- a data driver which generates a data voltage based on the compensated grayscale data and applies the data voltage to the display panel,
- wherein the compensator applies an individual weight to the weight depending on a normal state or defective states of the display panel to adjust the weight.
