Abstract

Disclosed is a thermal transfer substrate including a base substrate and a touch module on the base substrate. A side of the touch module which is in contact with the base substrate is adhesive, the adhesiveness decreasing under a first condition while increasing under a second condition. The present disclosure solves the problem that the manufacturing yield rate of touch display panels is relatively low, and improves the manufacturing yield rate of the touch display panels. The present disclosure is used for manufacturing a touch display panel.
