A laser irradiation device and a method of manufacturing an organic light emitting diode display device using the same. The approach includes a step of detecting whether a computer system is coupled to a packet switched network via the first communications line and if the computer system is coupled to the packet switched network, a step of concurrently enabling voice communications over the first communications line using a first voice telephony device coupled to the computer system. The data read from each one of the plurality of chips is stored in a corresponding one of a plurality of storage devices in response to the read strobe pulse associated with such one of the plurality of chips. Further, a tracking system configured to store tracking information associated with the object.
