A method of compensating for misalignments along a seam of first and second electronic panels installed for a display device is provided. Each of the first and second electronic panels includes a plurality of pixels formed in an i×j matrix, wherein i and j are integers at least one. The method includes 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.
