Temperature distribution of the circular heat source was studied by analyzing the heat transfer of the environment of the circular source for OLED. Circular nozzle source was used to fabricate thin organic layer as the organic material in it was heated, vaporized and deposited to the large size flat panel. Circular source for large size fat panel for OLED has been modified to obtain higher productivity and heat transfer characteristics was predicted using computer simulation. Fundamentals for OVPD process also was presented to estimate flow and heat transfer characteristics of the process which can increase the material efficiency.
