Method, apparatus and computer product to compensate for misaligned or overlapped electronic wallpapers

Apparatus of compensating for misalignments along a seam of first and second electronic panels installed for a display device, each of the first and second electronic panels including a plurality of pixels formed in an i×j matrix, wherein i and j are integers at least one, the apparatus comprising:

• a control device controlling a pixel driver for driving first pixels in a first column of the first electronic panel to alternately turn on the first pixels, wherein the first column is closest to the seam;
• a camera device placed over the seam to capture images for the respective first pixels in the first column under a control by the control device;
• and
• a pattern detector detecting each of the first pixels based on a corresponding one of the captured images,
• wherein the control device determines one of at least one horizontal displacement or a vertical displacement along the seam and compensates for the misalignments along the seam based on the determined at least one horizontal displacement or the vertical displacement.

A computer program product stored in a non-transitory computer-readable storage medium having computer readable program instructions, the computer readable program instructions read and carried out by a processor for performing a method of compensating for misalignments along a seam of first and second electronic panels installed for a display device, each of the first and second electronic panels including a plurality of pixels formed in an i×j matrix, wherein i and j are integers at least one, the method comprising:

• controlling a camera device to be placed over the seam;
• alternately turning on first pixels in a first column of the first electronic panel, the first column being closest to the seam,
• capturing, using the camera device, images for the respective first pixels;
• detecting, using a pattern detector, each of the first pixels based on a corresponding one of the captured images;
• determining one of at least one horizontal displacement or a vertical displacement along the seam;
• and
• compensating for the misalignments along the seam based on the determined at least one horizontal displacement or the vertical displacement.
