A method and system for configuring security devices on a security network. A gate insulating layer, a semiconductor layer, an ohmic contact layer and a conductor layer are sequentially deposited, and the conductor layer and the ohmic contact are patterned to form a data wire including a plurality of data lines, a source electrode and a drain electrode of the display area and data pads of the peripheral area, and an ohmic contact layer pattern thereunder. The target \u03b3 value is obtained from an ADIP of the disk.
