Patent ID: 8537185

Claim:
A laser induced thermal imaging apparatus comprising: a substrate stage including a magnet or magnetic substance, the substrate stage being adapted to receive an acceptor substrate and a donor film to be laminated to each other on the substrate stage, the acceptor substrate having a pixel region for forming pixels, each pixel comprising a first sub-pixel, a second sub-pixel, and two third sub-pixels, the donor film having an organic light emission layer to be transferred to the pixel region; a laser oscillator for irradiating a laser to the donor film; a contact frame adapted to be disposed between the substrate stage and the laser oscillator, and comprising a magnet configured to form a magnetic force with the substrate stage to adhere the acceptor substrate and the donor film to each other between the substrate stage and the contact frame; and a contact frame feed mechanism for moving the contact frame in a direction of the substrate stage, wherein the contact frame includes first and second frames, first and second openings through which the laser passes are formed respectively at the first and second frames, the first and second sub-pixels are formed corresponding to the first opening, and the two third sub-pixels are formed corresponding to the second opening, Wherein the first and second frames are alternately mounted to form emission layers of organic light emitting diodes corresponding to the first, second and third sub-pixels.
