Technique for reducing display crosstalk and systems implementing the same

A flat panel display, comprising:

• an array of pixels electrically addressable via a plurality of scan lines and a plurality of data lines;
• and
• a display driver module in electrical communication with the plurality of scan lines and the plurality of data lines, the display driver module being programmed to:
• (i) receive image data for displaying an image on the flat panel display, the image data comprising a grayscale value for each pixel;
• (ii) determine a grayscale delta for each pixel from the grayscale values where, for a given pixel addressable by a first scan line of the scan lines and a first data line of the data lines, the grayscale delta is a variation between the grayscale value for the given pixel and the grayscale value for another pixel addressable via the first data line and addressable via a scan line that is to be addressed prior to the first scan line when displaying the image;
• (iii) determine an aggregated grayscale delta for the first scan line by summing the grayscale deltas of each pixel addressable by the first scan line;
• (iv) determining that a magnitude of the aggregated grayscale delta for the first scan line equals or exceeds a threshold value, wherein the threshold value is a value of an aggregated grayscale delta that results in line crosstalk;
• (v) select, for image modification, a subset of pixels addressable by the first scan line;
• (vi) modify the image data for the selected subset of pixels addressable by the first scan line such that a magnitude of a modified aggregated grayscale delta for the first scan line is below the threshold value, thereby generating modified image data;
• and
• (vii) apply scan signals sequentially to the plurality of scan lines and data signals to the plurality of data lines to display the image on the flat panel display using the modified image data.

A non-transitory computer-readable medium containing instructions which when executed on a data processing apparatus in communication with a flat panel display causes the flat panel display to display an image, the flat panel display comprising an array of pixels electrically addressable via a plurality of scan lines and a plurality of data lines, the scan lines being addressed sequentially in a scan direction, a method for displaying the image when executed comprising:

• (i) receiving, at a display driver module for the flat panel display, image data for displaying the image on the flat panel display, the image data comprising a grayscale value for each pixel;
• (ii) determining a grayscale delta for each pixel from the grayscale values where, for a given pixel addressable by a first scan line of the scan lines and a first data line of the data lines, the grayscale delta is a variation between the grayscale value for the given pixel and the grayscale value for another pixel addressable by the first data line and addressable by a scan line that is to be addressed prior to the first scan line when displaying the image;
• (iii) determining an aggregated grayscale delta for the first scan line by summing the grayscale deltas of each pixel addressable by the first scan line;
• (iv) determining that a magnitude of the aggregated grayscale delta for the first scan line equals or exceeds a threshold value, wherein the threshold value is a value of an aggregated grayscale delta that results in line crosstalk;
• (v) selecting, for image modification, a subset of pixels addressable by the first scan line;
• (vi) modifying the image data for the selected subset of pixels addressable by the first scan line such that a magnitude of a modified aggregated grayscale delta for the first scan line is below the threshold value, thereby generating modified image data;
• and
• (vii) displaying the image on the flat panel display using the modified image data.
