A flexible display panel, display device and binding method thereof

Abstract

The invention discloses a flexible display panel, a display device and a binding method thereof. The flexible display panel includes a plurality of fan-out leads arranged in a fan-out area along a first direction; The virtual extension line of the lead wire intersects with the first intersection point on the reference line perpendicular to the first direction; the chip-on-chip film has a plurality of output pads arranged along the first direction and corresponding to the fan-out lead wires one by one; The virtual extension lines of the output pads corresponding to the fan-out leads of the zone intersect at the second intersection point on the reference line. In this way, when the size of the flexible display panel changes along the first direction, since the virtual extension lines of the one-to-one corresponding output pads and fan-out leads have the same angle with the reference line, it is possible to adjust the flexible display panel and The chip-on-chip film is bonded after relative position in the vertical first direction, so as to realize the correct alignment of the output pad and the fan-out lead, thereby improving the bonding yield and reliability.

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...
