Abstract
A method of operating on a flexible donor sheet, before or after organic material has been transferred to such sheet, to form a rigid edge frame to facilitate its mounting, including cutting notches in each of the four corners of the sheet, and folding the four notched edge portions of the sheet and securing the folded portions to the main body of the sheet to form at least four rigid edges so as to provide a rigid edge frame which can be readily mounted in an OLED device manufacturing process.
