    摘要： A method and an apparatus for making a light emitting display is provided. The apparatus includes a discharge device with an inlet and an outlet with the portion of the discharge device defining a delivery path. An actuating mechanism is moveably positioned along the delivery path. A substrate retaining device is positioned spaced apart from the outlet of the discharge device in the delivery path. The inlet of the discharge device is adapted to be connected to a pressurized source of a thermodynamically stable mixture of a compressed fluid and one of a hole transporting material, a light emitting material, and an electron transporting material. The compressed fluid is in a gaseous state at a location beyond the outlet of the discharge device and prior to the substrate retaining device.
