Flexible display substrate mother board and manufacturing method of flexible display substrate

Abstract

The embodiment of the invention provides a flexible display substrate mother board and a manufacturing method of a flexible display substrate, and relates to the display technical field. When a flexible substrate is separated from a bearing substrate, display components on the flexible substrate are prevented from being damaged, and uneven separation is avoided. The manufacturing method comprises the steps that a pattern layer for heating is formed on the bearing substrate, wherein the pattern layer for heating comprises a plurality of regional blocks which are arranged at intervals; the flexible substrate is formed on the substrate where the pattern layer for heating is formed, and the display components are formed on the flexible substrate, wherein the area of the flexible substrate is greater than the area of the pattern layer for heating; the flexible substrate is heated through the pattern layer for heating and is cut, the positions, corresponding to the regional blocks, of the bearing substrate are separated from the flexible substrate in a stripping mode, and the flexible display substrate is formed. When the flexible substrate and the bearing substrate are separated, the manufacturing method of the flexible display substrate needs to prevent the display components on the flexible substrate from being damaged and avoid the uneven separation.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display substrate motherboard and a method for manufacturing the flexible display substrate. Background technique [0002] Flexible display technology has developed rapidly in recent years, which has led to great progress in flexible displays from screen size to display quality. Whether it is the cathode ray tube (Cathode Ray Tube, referred to as CRT) that is on the verge of disappearing, or the current mainstream liquid crystal display (Liquid Crystal Display, referred to as LCD), they are essentially traditional rigid displays. Compared with traditional rigid displays, flexible displays have many advantages, such as impact resistance, strong shock resistance, light weight, small size, and more convenient to carry. [0003] Flexible displays can be mainly divided into three types: electronic paper (flexible electrophoretic display), flexible organic light-emitting d...

Problems solved by technology

[0004] However, when the laser beam is used for the lift-off process, although the intensity and focus depth of the laser beam are controlled, since the flexible substrate and each pattern layer of the display element formed on the flexible substrate are very thin, the light of the laser beam is still very thin. Will inevitably damage the display components

In addition, due to the limited beam area of ​​the laser beam, the flexible substrate and the hard carrier substrate need to be gradually peeled off by moving the laser beam during peeling, which will lead to uneven peeling of the flexible substrate and the carrier substrate. Phenomenon
