The method of manufacturing the OLED display device using the LITI apparatus includes arranging an acceptor substrate on a substrate stage; forming a donor film on the acceptor substrate; disposing a patterned mask above the acceptor substrate; irradiating the donor film with a laser beam generated by a laser beam generator through an opening of the mask; and transferring a pattern of the donor film onto the acceptor substrate. The LITI apparatus and the manufacturing method allow a transfer layer of a donor film to be easily transferred onto a substrate by scanning a laser beam without regard to a size of the substrate.

  • Patent number: 8697328
    Abstract: Disclosed herein is a film-type photodegradable transfer material, comprising: a support film; a resin protection layer; a photodegradable photoresist layer; and a cover film, wherein the resin protection layer has an adhesion force of 0.05 kgf or less. When the film-type photodegradable transfer material is used to form a fine circuit pattern, such as a printed circuit board or the like, the resolution of the pattern can be increased by minimizing the distance between a mask and a photosensitive resin layer at the time of exposure, and work can be performed in the form of a sheet or a roll to roll process can be applied to the work even when the support film has been removed before an exposure process.

    Abstract: A thermal transfer method for selectively transferring a red organic light material of a transfer layer from a donor substrate to a recipient substrate to form a red organic light emitting element. The donor substrate has a reflecting layer in a planned formation region of the transfer layer and an absorbing layer in a region other than the planned formation region of the transfer layer. The transfer layer is formed on an area on the front face side of the base. The transfer layer in the region where the absorbing layer is formed is selectively removed. the donor substrate and the other substrate are placed in opposition. The transfer layer on the reflecting layer is transferred to the recipient substrate.
