Processing method and processing system of a flexible substrate

A method of processing a flexible substrate, comprising:

• measuring a first expansion volume of the flexible substrate, wherein the first expansion volume is a contraction volume generated when the flexible substrate is lifted off from a rigid substrate;
• and
• applying a first application pressure to the flexible substrate to laminate the flexible substrate on a base substrate, and then removing the first application pressure;
• wherein according to a first corresponding relationship between a first pressure applied to the flexible substrate and a compressive expansion volume generated by the flexible substrate in compression and according to the first expansion volume, the first application pressure is selected to allow a second expansion volume of the flexible substrate to at least partially compensate for the first expansion volume, the second expansion volume is a relaxation volume;
• the method further comprises:
• establishing the first corresponding relationship between the first pressure applied to the flexible substrate and the compressive expansion volume of the flexible substrate;
• wherein establishing the first corresponding relationship between the first pressure applied to the flexible substrate and the compressive expansion volume of the flexible substrate comprises:
• obtaining a change curve of the second expansion volume of the flexible substrate with respect to the first pressure;
• or
• dividing the second expansion volume of the flexible substrate into a plurality of sections by size, wherein each of the sections corresponds to one value of the first pressure.
