Flexible display panel, display device and binding method for flexible display panel

Abstract

The invention discloses a flexible display panel, a display device and a binding method for the flexible display panel. The flexible display panel comprises a plurality of fanout leads, wherein the fanout leads are arranged in a fanout region along the first direction; virtual extension lines of the fanout leads in a side region of the fanout region are at least intersected at a first intersection point in a reference line vertical to the first direction; a chip on film comprises a plurality of output pads which are arranged along the first direction and correspond to the fanout leads one by one; and virtual extension lines of the output pads corresponding to the fanout leads in the side region are at least intersected at a second intersection point in the reference line. When the size of the flexible display panel changes along the first direction, the included angles between the virtual extension lines of the output pads and the fanout leads, which are in one-to-one correspondence, and the reference line are the same, so that correct alignment of the output pads and the fanout leads is achieved by adjusting the relative positions of the flexible display panel and the chip on film in the direction vertical to the first direction and then binding the flexible display panel and the chip on film, and the binding yield and the reliability are improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display panel, a display device and a binding method thereof. Background technique [0002] Flexible display technology has been a research hotspot in the field of display technology in recent years. Because of its advantages of being thinner, more shock-resistant, and lighter, it will be widely used in civilian and military fields. Flexible display can be defined as the substrate of the display panel made of a very thin flexible substrate, which can be bent to a radius of curvature of only a few centimeters or less without damaging the display function of the display panel. [0003] When making a flexible display device, the flexible substrate is generally fixed on the glass substrate first, and then the subsequent flexible display panel manufacturing process is performed. This process is compatible with the existing display panel manufacturing equipment. Aft...
