The invention discloses a flexible display panel with fingerprint identification and a manufacturing method, which can reduce the thickness of the display panel, simplify the production process steps, and improve the fingerprint identification performance and damage resistance performance of the flexible display panel. The flexible display panel with fingerprint identification includes a flexible substrate, an inorganic layer and a flat layer; wherein, the flexible substrate includes a display area and an edge area, the display area has a fingerprint identification area, and the edge area has a bending area; the surface of one side of the flexible substrate is bonded with an inorganic layer, and the inorganic layer is hollowed out corresponding to the fingerprint recognition area and provided with a black filter flat layer, and the inorganic layer is hollowed out corresponding to the bending area and provided with a black A flat layer: the inorganic layer, the black filter flat layer and the black flat layer are attached to the side away from the flexible substrate with a flat layer.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a flexible display panel with fingerprint identification and a manufacturing method. Background technique [0002] With the development of display technology, the display effect of display devices is getting better and better, which brings people a good visual experience. However, due to the improvement of living standards, people's requirements for display devices are not limited to display effects, but also require display It has a variety of functions. Therefore, fingerprint recognition and flexible display panels are widely used in display screens of electronic devices such as mobile phones, personal digital assistants (PDAs), and computers. [0003] At present, the fingerprint recognition technologies mainly adopted in the industry are capacitive fingerprint recognition technology and photosensitive fingerprint scanning technology. The position of the valley thus forms th...
