Abstract
A method for selective transfer of a color organic layer from a donor layer onto a device having an array of pixels with each pixel formed from color subpixels, includes the steps of providing a substrate having opposing first and second surfaces; forming a light transmissive heat insulating layer over the first surface of the substrate; forming a light absorbing layer over the heat insulating layer; providing the substrate with an array of openings extending from the second surface to the heat insulating layer, the number and positions of the openings corresponding to the number and positions of the color subpixels of the device, and each opening having a size equal to or smaller than the size of the color subpixel. The method also includes providing a transferable color forming organic donor layer formed on the light absorbing layer; positioning the device in contact or close proximity to the donor layer in an oriented relationship between the openings in the substrate and the corresponding color subpixels on the device; and employing a source of radiation for producing sufficient heat at the light absorbing layer over the openings to cause the selective transfer of portions of the transferable color forming organic donor layer to the corresponding color subpixels of the device.
