摘要： An organic vapor jet printing (OVJP) device is provided that includes an OVJP print die having one or more delivery channels to deliver organic material and carrier gas to a region below the print die and one or more exhaust channels to remove material from below the print die. A directly-heated delivery line connected to the one or more delivery channels and a source of the organic material external to the OVJP print die includes a resistive material and a plurality of electrical connections to the resistive material. When a current is applied to the resistive material via the plurality of electrical connections, the resistive material heats the interior of the directly-heated delivery line.
