1. A method of compensating data, the method comprising:
- providing a look-up table divided into a first area, a second area and a boundary area between the first and second areas, said first, second and boundary areas being defined by a first previous reference value, a second previous reference value greater than the first previous reference value, a first current reference value and a second current reference value less than the first current reference value; and
generating compensation data for a current frame based on whether grayscale data of said current frame and of a previous frame satisfy a condition for one of the first, second or boundary areas.

Abstract
A method of compensating data uses a look-up table divided into a first area, a second area and a boundary area between the first and second areas defined by a first previous reference value, a second previous reference value greater than the first previous reference value, a first current reference value and a second current reference value less than the first current reference value. A compensation data of a current frame is generated based on to which one of the first, second and boundary areas grayscale data of previous and current frames belongs.

7. A method of compensating data, the method comprising:
-
generating a first compensation data for a current frame, when grayscale data of a previous frame has a value less than a first previous reference value and grayscale data of a current frame has a value greater than a first current reference value; generating a second compensation data for the current frame, when grayscale data of the previous frame has a value greater than a second previous reference value greater than the first previous reference value or grayscale data of the current frame has a value less than a second current reference value less than the first current reference value; and generating a third compensation data for the current frame when grayscale data of the previous frame has a value between the first and second previous reference values and grayscale data of the current frame has a value greater than the second current reference values, or when grayscale data of the current frame has a value between the first and second current reference values and grayscale data of the previous frame has a value less than the second previous reference value. - View Dependent Claims (8, 9, 10, 11, 12)

13. A data compensation apparatus for compensating display data, comprising:
a frame memory for storing grayscale data of a previous frame; and
a compensation part having a look-up table divided into a first area, a second area and a boundary area between the first and second areas, said first, second, and boundary areas defined by a first previous reference value, a second previous reference value greater than the first previous reference value, a first current reference value and a second current reference value less than the first current reference value, said compensation part being configured to generate compensation data for a current frame based on whether grayscale data of said current frame and of said previous frame satisfy a condition for one of the first, second or boundary areas.- View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
