Abstract

The invention provides a flexible display motherboard and a manufacturing method of a flexible display screen, belonging to the technical field of flexible display screens. The flexible display motherboard comprises a carrier substrate, a flexible substrate, and a display device arranged on the flexible substrate; a plurality of heating resistors are arranged between the carrier substrate and theflexible substrate; a bonding force formed by the heating resistors and the carrier substrate is greater than that formed by the heating resistors and the flexible substrate; the flexible substrate isprovided with extension parts filled between the adjacent heating resistors; a hydrogen bond is formed by molecular chain structures of the extension parts and a molecular chain structure of the carrier substrate; the heating resistors are used for heating the carrier substrate and the flexible substrate, so that the hydrogen bond is destroyed by heat generated by the heating resistors. Accordingto the flexible display motherboard and the manufacturing method of the display screen, the flexible substrate can be stripped from the carrier substrate, and the display effect of the flexible display screen can be also improved.

Description

technical field [0001] The invention relates to the technical field of flexible display screens, in particular to a flexible display motherboard and a method for manufacturing a flexible display screen. Background technique [0002] In recent years, flexible display technology has developed rapidly, and its manufacturing process and technology have been continuously improved, resulting in continuous increase in the size of flexible displays and continuous improvement in display quality. [0003] In the manufacturing process of the flexible display, it is necessary to adhere a flexible substrate on a hard and flat carrier substrate, and then manufacture electronic display devices on the flexible substrate and complete the fabrication of the flexible display motherboard, and then remove the flexible substrate from The carrier substrate is peeled off to obtain a flexible display. At present, laser lift-off is often used to lift off the flexible substrate. [0004] However, wh...
