1. A method for adjust luminance-chrominance of pixels of two LED panels, the method being utilized in a calibrating device, and the method comprising:
analyzing an image of a target region which a seam between the two LED panels disposed side by side is in, to obtain characteristic data associated with the seam;
comparing the characteristic data associated with the seam with a predetermined value to generate a comparison result; and
adjusting grayscale data of pixels of a first LED panel of the two LED panels based on the comparison result, for adjusting luminance-chromaticity of the pixels, wherein the pixels which grayscale data are adjusted comprises at least one pixel line of the first LED panel adjacent to the seam, wherein the at least one pixel line is in a first direction or a second direction, and the first direction is perpendicular to the second direction.
