Claim 0:
1. A method of preparing an organic light-emitting display substrate comprising a display area and a plurality of opening areas located in the display area, the method comprising:
forming a flexible substrate on a support substrate, such that the support substrate supports the flexible substrate, wherein the flexible substrate comprises a plurality of openings each of which is located in a respective opening area;
forming an organic light-emitting device layer on a side of the flexible substrate away from the support substrate, such that the organic light-emitting device layer is located in the display area;
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, wherein the encapsulation layer comprises first to-be-etched portions, each of which is located in a respective opening and extends in a direction intersecting side walls of the opening;
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.
