Problems solved by technology

Since bubbles or foreign objects are likely to be generated in the polyimide film production process, it is easy to cause incomplete peeling between the flexible substrate and the rigid substrate during the peeling process of the flexible substrate and the rigid substrate, resulting in perforation of the flexible substrate or the film layer of the flexible substrate. Peeling and other issues
These problems will not only damage the film layer of the flexible substrate and make the packaging of the light-emitting device abnormal, but also make it easier for water and oxygen in the air to invade the light-emitting device through the damaged position of the flexible substrate, resulting in display failure.

Abstract

The invention provides a display panel manufacturing method comprising the following steps: a flexible protection layer is made on a rigid substrate, a flexible substrate is formed on the flexible protection layer, an illuminating device is made on the flexible substrate, a packaging structure is formed by the illuminating device, and therefore the illuminating device can be packaged on the flexible substrate; the rigid substrate is separated from the flexible protection layer; the flexible protection layer, the illuminating device and the packaging structure jointly form a display panel. Theinvention also provides the display panel. According to the display panel and the manufacturing method therefor, the flexible substrate can be prevented from being damaged while being peeled off the rigid subtracted, and reliability of the display panel can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) has the advantages of fast response, wide temperature range, self-illumination, flexible display, etc. The third-generation display technology after Liquid Crystal Display (LCD) / Light Emitting Diode (LED). With the continuous increase of market demand, the field of OLED technology has achieved extensive coverage in the display field. [0003] Compared with traditional OLED display panels with rigid substrates, OLED display panels with flexible substrates have advantages such as portability and bendability, and are receiving more and more attention and favor. At present, the flexible substrate of the OLED display panel is first fabricated on the rigid substrate, and then the flexible substrate is peeled off the rigid substrate by a lift-off technique to form a f...
