Organic matter vapor deposition device and organic light emitting display manufactured thereby

Abstract

An organic material deposition device configured to sense a deposition amount of an organic material deposited in a vacuum chamber by detecting a back propagation characteristic variation of a passive radio frequency identification (RFID) sensor. The organic material deposition device includes: a chamber configured to perform an organic material deposition process therein; a deposition source mounted in the chamber to vaporize an organic material; a deposition mask mounted to face the deposition source and configured to bond a substrate at an opposite side to the deposition source; an antenna mounted in the chamber to receive back propagation from a radio frequency identification (RFID) sensor; and a radio frequency (RF) reader connected to the antenna to measure an organic material deposition amount from a variation of the back propagation.
