Abstract
Organic light-emitting display substrates and methods of preparing the same, and organic light-emitting display apparatuses are provided. An organic light-emitting display substrate includes a display area and opening areas in the display area. A method of preparing the organic light-emitting display substrate includes: forming a flexible substrate on a support substrate, where the flexible substrate includes openings located in the opening areas respectively; forming an organic light-emitting device layer on a side of the flexible substrate away from the support substrate; forming an encapsulation layer on a side of the organic light-emitting device layer away from the flexible substrate, such that the encapsulation layer covers the organic light-emitting device layer and the openings, where the encapsulation layer includes first to-be-etched portions; etching the first to-be-etched portions to remove the first to-be-etched portions; and peeling off the support substrate from the flexible substrate to obtain the organic light-emitting display substrate.
