Laser induced thermal imaging apparatus and fabricating method of organic light emitting diode using the same
A laser induced thermal imaging apparatus and a fabricating method of organic light emitting diodes using the same, which laminate an acceptor substrate and a donor film using a magnetic force in vacuum, and are used to form a pixel array on the acceptor substrate. A substrate stage includes a magnet or magnetic substance. The acceptor substrate has a pixel region for forming first, second, and third sub-pixels, and the donor film has an organic light emission layer to be transferred to the pixel region. A laser oscillator irradiates a laser to the donor film. A contact frame is adapted to be disposed between the substrate stage and the laser oscillator, and is used to form a magnetic force with the substrate stage. The contact frame includes an opening through which the laser passes. A contact frame feed mechanism moves the contact frame in a direction of the substrate stage.
