Abstract
A laser induced thermal imaging apparatus for imaging an imaging layer of a donor film on an acceptor substrate. The laser induced thermal imaging apparatus includes: a substrate stage having an electromagnet, and adapted to receive an acceptor substrate having a pixel area of the organic light emitting device and a donor film including the organic light emitting layer to be imaged on the pixel area; a laser oscillator for irradiating a laser on the donor film; a contact frame adapted to be located between the substrate stage and the laser oscillator and including an opening portion of a pattern corresponding to a part to be imaged of the donor film and a permanent magnet for forming a magnetic force with the substrate stage; and a contact frame moving mechanism for moving the contact frame toward the substrate stage.
