Abstract
An organic light emitting display device and a driving method thereof are disclosed. The display device has sub-pixels of multiple colors. In one aspect, the organic light emitting display device detects sub-pixels which are positioned at the edges of the panel. Data for the sub-pixels on the edges are reduced so that colors on the edges are less observable.
Claims16
An organic light-emitting display panel, comprising:
- a first group of pixel rows and columns comprising odd-numbered pixel rows and odd-numbered pixel columns;
- a second group of pixel rows and columns comprising even-numbered pixel rows and even-numbered pixel columns;
- first color sub-pixels and second color sub-pixels arranged only in the pixel rows and columns of one of the first and second groups, wherein the first color sub-pixels and the second color sub-pixels are alternately arranged in each of the pixel rows and columns of the one of the first and second groups;
- and
- third color sub-pixels arranged in the pixel rows and columns of another one of the first and second groups,
- wherein a size of one of the third color sub-pixels is smaller than a size of one of the first or second color sub-pixels.

- a data processor configured to receive first data and to generate second data based on the first data, wherein the data processor is configured to generate the second data by changing grayscale values of the first data for the first, second, or third color sub-pixels positioned in first and last pixel rows from among the pixel rows and first and last pixel columns from among the pixel columns of the display panel;
- and
- a data driver configured to drive data lines connected to the first, second, and third color sub-pixels in response to the first or second data.
