[0061] Figure 4 A flow chart showing a method for releasing a flexible display device according to the first embodiment of the present invention is shown. Such as Figure 4 As shown, the release method of the flexible display device of the present invention includes the following steps: forming a releaseable flexible substrate on a support carrier (step S110 ). On the releasable flexible substrate, heat treatment is performed on the first heat treatment area on the releasable flexible substrate according to a preset cutting line position for forming the flexible display device (step S120 ). Step S120 can increase the adhesive force between the first heat treatment area and the support carrier. An electronic component layer is formed on the releasable flexible substrate (step S130). A display material layer is formed on the electronic component layer (step S140). Cutting the releasable flexible substrate along the cutting line (step S150 ). The cut detachable flexible sub...

Abstract

The invention provides a release method of a flexible display device. A releaseable flexible substrate is formed on a support carrier. On the releaseable flexible substrate, the position of the cutting line of the flexible display device is formed according to at least one preset. The first heat treatment area on the detachable flexible substrate is heat treated to increase the adhesion between the first heat treatment area and the support carrier, an electronic component layer is formed on the detachable flexible substrate, and a display is formed on the electronic component layer. Material layer, cutting the detachable flexible substrate along the cutting line, and separating the cut detachable flexible substrate from the support carrier, and the separated detachable flexible substrate is sequentially arranged with cut electronic component layers And the display material layer, the present invention greatly simplifies the structure and manufacturing process of the flexible substrate, does not need to use a release layer and laser to remove it, greatly improves the yield of flexible electronic components and greatly reduces the production cost.

Description

technical field [0001] The invention relates to the field of flexible display devices, in particular to a release method of a flexible display device that prevents the flexible substrate from breaking during cutting by enhancing the local adhesion between the flexible substrate and the supporting substrate Background technique [0002] Flexible displays, also known as rollable displays, are bendable and deformable display devices made of flexible materials and visible flexible panels. Flexible displays are one of the hottest trends in display technology. Although it has not yet been popularized in the market, it is foreseeable that scroll-type PDAs or e-book readers are no longer far away, and large-format wall-mounted flexible displays will soon become a reality. For example, all visual materials, including various books, newspapers, magazines and video files, can be presented through this display and can be viewed anytime and anywhere. Although currently popular MP4 play...
