An organic light-emitting diode (OLED) display is disclosed. In one aspect, the OLED display includes red, green, and blue pixels. Each pixel includes a pixel electrode, a hole auxiliary layer formed over the pixel electrode, and an organic emission layer formed over the hole auxiliary layer. Each pixel also includes an electron auxiliary layer formed over the organic emission layer, and a common electrode formed over the electron auxiliary layer. Each of the red and green pixels further includes a host layer formed between the hole auxiliary layer and the organic emission layer and a resonance layer formed between the host layer and the organic emission layer.

A laser induced thermal imaging (LITI) apparatus and a method of making an electronic device using the same are disclosed. The LITI apparatus includes a chamber, a substrate support, a contact frame, and a laser source or oscillator. The LITI apparatus transfers a transferable layer from a film donor device onto a surface of an intermediate electronic device. The LITI apparatus uses a magnetic force to provide a close contact between the transferable layer and the surface of the intermediate device. The magnetic force is generated by magnetic materials formed in two components of the LITI apparatus that are spaced apart interposing transferable layer and the surface of the intermediate device. Magnets or magnetic materials are formed in the two following components of the LITI apparatus: 1) the intermediate device and the film donor device; 2) the intermediate device and the contact frame; 3) the substrate support and the film donor device; or 4) the substrate support and the contact frame.

A manufacturing method using an additional heat-treatment process for a donor film with improved surface roughness. The improved donor film, used in a laser induced thermal imaging method, is capable of enhancing the lifetime of products and reducing the defect rates thereof. A manufacturing method for a donor film according to the invention, includes: providing a donor film comprising a base film, a light-to-heat conversion layer and an organic film; heating the donor film to provide a heat-treated donor film; and cooling the heat-treated donor film. The surface roughness of a donor film can be improved, and the non-uniform distribution of a laser on a region subjected to the LITI process can be minimized to prevent the over- or under-transfer of an transferred organic film, etc., and the non-uniform adhesion of the transferred organic film with an acceptor substrate.
