A method of integrating barcode information and EDID firstly inputs barcode information and temporarily stores the information in a first storage device; reads a pre-stored barcode rule and a pre-stored check code from a second storage device, wherein the barcode rule is defined with relevant data of plural codes included in the barcode information; then, respectively stores the plural codes included in the barcode information into corresponding storage spaces of the first storage device according to the barcode rule; next, determines whether a specific code of the barcode information matches with the check code; if the specific code of the barcode information matches with the check code, reads a pre-stored EDID from an EDID burning device, and integrates the EDID with the plural codes of the barcode information so as to generate a new EDID; finally, performs a burning operation to a display device based on the new EDID.
