Problems solved by technology

[0003] Existing GOA Bending: The process of bending and attaching the flexible OLED GOA area to the back to achieve the long-side full-screen display effect still has certain technical defects. For example, the GOA area is very narrow (about 5mm) and the bending device is used for vacuum The adsorption process is difficult to ensure the stability of bending
In addition, the curved surface pressing used in the existing preparation method is also difficult to ensure the adhesion effect, which is likely to cause the risk of fragmentation

Abstract

The invention discloses a bending preparation method of a GOA region of a flexible display panel. The flexible display panel includes: a substrate and a GOA bendable region arranged on the edge of the substrate, including the following steps: pasting an inflatable component on the GOA bendable region The servo motor drives the inflatable component to rotate and bend the GOA bendable area to the back surface of the substrate; the inflatable component is inflated to press and connect the GOA bendable area to the back surface of the substrate. The present invention also discloses a flexible display panel prepared by the above-mentioned bending preparation method of the GOA region of the flexible display panel. The implementation of the flexible display panel and the bending preparation method of the GOA region of the present invention improves the stability of GOA bending and the reliability of curved surface pressing, and improves assembly efficiency and product yield.

Description

technical field [0001] The invention relates to the field of display panel manufacturing, in particular to a flexible display panel and a bending preparation method of a GOA region thereof. Background technique [0002] With the continuous maturity of flexible OLED display technology, the types of flexible display products are also continuously diversified. At this stage, borderless display products have become the mainstream of the market. Therefore, their process requirements are getting higher and higher. Among them, GOA (GateDriver on Array, array substrate row drive) bending technology is one of the important technologies to achieve borderless. [0003] Existing GOA Bending: The process of bending and attaching the flexible OLED GOA area to the back to achieve the long-side full-screen display effect still has certain technical defects. For example, the GOA area is very narrow (about 5mm) and the bending device is used for vacuum The adsorption process is difficult to ...
