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 at least one defective display pixel, the method comprising:
- generating first, second, and third sub-frames using image data for the image, information that identifies the at least one defective display pixel, a first pixel offset between the first sub-frame and the second sub-frame, and a sub-pixel offset between the first sub-frame and the third sub-frame; and
alternating between displaying the first sub-frame in a first position, displaying the second sub-frame in a second position spatially offset from the first position by the first pixel offset, and displaying the third sub-frame in a third position spatially offset from the first position by the sub-pixel offset.

Abstract
A method of displaying an image with a display device having at least one defective display pixel is provided. The method comprises generating first, second, and third sub-frames using image data for the image, information that identifies the at least one defective display pixel, a first pixel offset associated with the second sub-frame, and a sub-pixel offset associated with the third sub-frame, and alternating between displaying the first sub-frame in a first position, displaying the second sub-frame in a second position spatially offset from the first position according to the first pixel offset, and displaying the third sub-frame in a third position spatially offset from the first position and the second position according to the sub-pixel offset.

9. A system for displaying an image, the system comprising:
-
a display device having a defective display pixel; and an image processing unit configured to generate first, second, and third sub-frames using image data for the image, information that identifies the defective display pixel, a first pixel offset between the first sub-frame and the second sub-frame, and a sub-pixel offset between the first sub-frame and the third sub-frame; wherein the display device is adapted to alternately display the first sub-frame in a first position, display the second sub-frame in a second position spatially offset from the first position by the first pixel offset, and display the third sub-frame in a third position spatially offset from the first position by the sub-pixel offset. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A system for displaying an image using a display device having a defective display pixel, the system comprising:
-
means for generating first, second, and third sub-frames using image data for the image, information that identifies the defective display pixel, a first pixel offset between the first sub-frame and the second sub-frame, and a sub-pixel offset between the first sub-frame and the third sub-frame; and means for alternating between displaying the first sub-frame in a first position, displaying the second sub-frame in a second position spatially offset from the first position by the first pixel offset, and displaying the third sub-frame in a third position spatially offset from the first position by the sub-pixel offset. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A non-transitory computer-readable medium storing computer-executable instructions that, when executed by a computer, perform a method of generating a first sub-frame, a second sub-frame associated with a pixel offset from the first sub-frame, and a third sub-frame associated with a sub-pixel offset from the first sub-frame for display at spatially offset positions by a display device having a defective display pixel to generate the appearance of an image, comprising:
-
calculating a first sub-frame pixel value associated with the defective display pixel for the first sub-frame; calculating a second sub-frame pixel value associated with the defective display pixel for the second sub-frame based on the pixel offset from the first sub-frame; and calculating at least third and fourth sub-frame pixel values associated with the defective display pixel for the third sub-frame based on the sub-pixel offset from the first sub-frame. - View Dependent Claims (25, 26)
