Patent ID: 8842144

Claim:
A method of manufacturing an organic light emitting diode (OLED) display device using a laser induced thermal imaging method, the method comprising: 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 patterned mask; and transferring a pattern of the donor film onto the acceptor substrate, wherein the donor film comprises a base film, a light-to-heat conversion (LTHC) layer formed on the base film, and a transfer layer formed on the LTHC layer, and wherein the transfer layer is in direct contact and is attached to the acceptor substrate, wherein a width of the patterned mask is less than or equal to a length of each pixel region on which emissive layers are formed and arranged along a second direction of the acceptor substrate, and wherein the length of the patterned mask is sufficient to cover a length of the acceptor substrate, in a first direction of the acceptor substrate, on which the emissive layers are formed and arranged on the same line along the first direction of the acceptor substrate.
