    摘要: Disclosed are a cutting method of flexible display panel, a controlling device in the cutting method and a cutting apparatus of flexible display panel. The cutting method comprises steps of placing a transparent substrate (21) carried with a flexible film layer (22) on a base (10); cutting only the transparent substrate (21) by means of a cutting tool (30); obtaining a cutting trace of the cutting tool (30); and controlling a laser knife (40) to cut the flexible film layer (22) carried on the transparent substrate (21) along the cutting trace of the cutting tool cutting the transparent substrate. In this way, by controlling the laser knife (40) to cut the flexible film layer (22) disposed on the transparent substrate (21) following the cutting trace of the cutting tool (30) cutting the transparent substrate (21), the flexible film layer (22) can be completely cut at the same time when or after the transparent substrate (21) is completely cut, so as to avoid rough selvedges during cutting the flexible film layer (22), thereby improving the cutting effect of cutting the flexible display panel; besides, in case that the cutting tool (30) and the laser knife (40) operate in parallel cutting mode, it can also improve the cutting efficiency.

    摘要: The present disclosure provides a flexible display device, wherein there is a flexible support structure fixed on a surface of the flexible display module, which is used to disperse stress. During use of the flexible display device, the flexible support structure can be used to disperse the point force or linear force that the flexible display device is subject to when being bent into even planar force. Besides, the flexible support structure can reduce the stress exerted on the flexible display module, avoiding delamination among the film layers caused by local stress concentration on the flexible display module. In addition, given the same thickness of the flexible display module, the flexible display device can be bent to a smaller bending radius.
