Abstract:
The present disclosure provides a method for manufacturing a flexible substrate. The method includes forming at least two flexible substrate layers in a stacking form on a surface of a glass baseplate, wherein a first flexible substrate layer of the flexible substrate layers relatively close to the glass baseplate has a refractive index less than a refractive index of a second flexible substrate layer of the flexible substrate layers relatively far from the glass baseplate; forming a water and oxygen blocking layer on a surface of the second flexible substrate layers, wherein the water and oxygen blocking layer has a refractive index greater than the refractive index of the second flexible substrate layers disposed below the water and oxygen blocking layer.

Claim (Index 11):
The method according to  claim 9 , wherein the step S 201  comprises:\n providing 4,4\u2032-diaminodiphenyl ether as a diamine, and 4,4\u2032-(hexafluoroisopropylidene)diphthalic anhydride and pyromellitic dianhydride as dianhydrides, and then dissolving 4,4\u2032-diaminodiphenyl ether, 4,4\u2032-(hexafluoroisopropylidene)diphthalic anhydride and pyromellitic dianhydride in N-methylpyrrolidone, so as to form a first polyamic acid solution containing 10-14% of fluorine, wherein a solid content of the first polyamic acid solution is 10-14%; \n coating the first polyamic acid solution on the surface of the glass baseplate; and \n heating a coating layer of the first polyamic acid solution, wherein a heating temperature is ramped up to 300-400\u00b0 C. in accordance with a predetermined procedure, so as to cure the coating layer of the first polyamic acid solution to form the first polyimide layer; and \n wherein the step S 202  comprises: \n dissolving 9,9-bis(4-(4-amino-3-hydroxy)phenoxy)phenylfluorene and 4,4\u2032-(hexafluoroisopropylidene)diphthalic anhydride of same moles in isoquinoline, so as to form a second polyamic acid solution, wherein the second polyamic acid solution includes polyamic acid and polyimide, and a solid content of the second polyamic acid solution is 13-17%; and then adding zirconium tetra-n-butoxy into the second polyamic acid solution, such that a ratio of polyimide to zirconium tetra-n-butoxy is 1:1.5; \n coating the second polyamic acid solution on a surface of the first polyimide layer; and \n heating a coating layer of the second polyamic acid solution, wherein the heating temperature is ramped up to 300-350\u00b0 C. in accordance with the predetermined procedure, so as to cure the coating layer of the second polyamic acid solution to form the second polyimide layer.
