Abstract
Making a high absorption donor substrate for providing one or more OLED materials to an OLED device by: providing an absorber anti-reflection layer over a transparent support element, the anti-reflection layer having the real portion of its index of refraction greater than 3.0, and a thickness near the first reflectivity minimum at the wavelength of interest; providing a metallic heat-absorbing layer over the anti-reflection layer for absorbing laser light which passes through the transparent support element and the anti-reflection layer; and selecting the transparent support element, the anti-reflection layer, and the metallic heat-absorbing layer to have an average reflectivity of less than 10%, and the micro reflectivity variation due to variations in the thickness of the transparent support element of less than 10% at the wavelength of interest; and providing one or more organic material layers in the absence of a binder material, over the metallic heat-absorbing layer.
