Abstract: A transportation system of a cassette comprises a port and a system controller. The port accommodates a cassette carrying a glass substrate, and the port includes displacement sensors for sensing a position of a cassette. The system controller calculates a distortion amount of the cassette using sensed values of the cassette and determines if the cassette is in a normal settlement status by comparing the distortion amount with a tolerance value. Therefore, the position of the cassette can be automatically taught without clamping operation of a clamping device clamping the cassette disposed in the port, thereby preventing defects of the glass substrate by removing various defect-causing factors such as particles and static electricity that may occur during a conventional clamping operation. In particular, quality defects of OLED can be eliminated by preventing particles and static electricity that affect product quality defects in the OLED manufacturing process.
