System and method for correcting defective pixels of a display device
First Claim
1. A method of displaying an image with a display device having a plurality of defective pixels, the method comprising:
- identifying first and second numbers of stuck-on-stuck pixels caused by the plurality of defective pixels for first and second offsets, respectively, between a first sub-frame and a second sub-frame;
selecting the first offset as a selected offset in response to the first number being less than the second number and the second offset as the selected offset in response to the second number being less than the first number;
generating the first sub-frame and the second sub-frame using image data for the image;
adjusting a first sub-frame pixel value in the first sub-frame associated with one of the plurality of defective pixels; and
alternating between displaying the first sub-frame in a first position and displaying the second sub-frame in a second position, the second position displaced from the first position by an amount defined by the selected offset.

Abstract
A method of displaying an image with a display device having a plurality of defective pixels is provided. The method comprises selecting an offset between a first sub-frame and a second sub-frame using information associated with the plurality of defective pixels, generating the first sub-frame and the second sub-frame using image data for the image, adjusting a first sub-frame pixel value in the first sub-frame associated with one of the plurality of defective pixels, and alternating between displaying the first sub-frame in a first position and displaying the second sub-frame in a second position, the second position displaced from the first position by an amount defined by the offset.

12. A system for displaying an image, the system comprising:
-
an image processing unit; and a display device having a plurality of defective pixels; wherein the image processing unit is configured to determine a selected offset from one of a plurality of possible offsets between a first sub-frame and a second sub-frame with a lowest number of stuck-on-stuck pixels caused by the plurality of defective pixels, wherein the image processing unit is configured to generate a first sub-frame and a second sub-frame using image data for the image, information associated with the plurality of defective pixels, and the selected offset, wherein the display device is configured to alternately display the first sub-frame in a first position and display the second sub-frame in a second position, and wherein the second position is displaced from the first position according to the selected offset. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A system for displaying an image using a display device having a plurality of detective pixels, the system comprising:
-
means for selecting a selected offset from one of a plurality of possible offsets between a first sub-frame and a second sub-frame with a lowest number of stuck-on-stuck pixels; means for generating the first sub-frame and the second sub-frame using image data for the image, the information associated with the plurality of detective pixels, and the selected offset; and means for sequentially displaying the first sub-frame in a first position and displaying the second sub-frame in a second position which is displaced from the first position according to the selected offset. - View Dependent Claims (24)

25. A computer-readable medium storing instructions readable and executable by a computer for causing the computer to perform a method of generating a first sub-frame and a second sub-frame for display at spatially offset positions defined by a selected offset by a display device having a plurality of defective pixels to generate the appearance of an image, comprising:
-
determining the selected offset as one of a plurality of possible offsets with a lowest number of stuck-on-stuck pixels caused by the plurality of defective pixels; generating the first sub-frame including adjusting a first plurality sub-frame pixel values of the first sub-frame associated with the plurality of defective pixels; and generating the second sub-frame including adjusting a second plurality sub-frame pixel values of the second sub-frame associated with the plurality of defective pixels. - View Dependent Claims (26, 27, 28, 29)
