Problems solved by technology

The existing capacitive fingerprint recognition technology needs to separately set hardware devices such as tactile switches, capacitive elements, and fingerprint recognition sensors at the fingerprint touch position, which increases the process time and design cost, and the fingerprint recognition of this technology cannot be set in the display area.
[0004] In order to reduce the lower frame of the existing flexible display device, the bottom of the flexible display panel adopts the bottom bending technology; the inorganic layer is easy to break when it is bent

Abstract

The invention discloses a fingerprint identification flexible display panel and a manufacturing method thereof. The fingerprint identification flexible display panel and the manufacturing method thereof can reduce the thickness of the display panel, simplify the production processes and improve the finger identification function and the wear-resisting performance of the flexible display panel. Thefingerprint identification flexible display panel comprises a flexible substrate, an inorganic layer and flat layers, wherein the flexible substrate comprises a display area and a boundary area, theinside of the display area is provided with a fingerprint identification area, and the inside of the boundary area is provided with a bent area; the inorganic layer is adhered to one surface of the flexible substrate, the area of the inorganic layer, which corresponds to the fingerprint identification area, is hollowed out and provided with a black filter flat layer, and the area of the inorganiclayer, which corresponds to the bent area, is hollowed out and provided with a black flat layer; one sides of the inorganic layer, the black filter flat layer and the black flat layer, which back to the flexible substrate, are provided with the flat layers through adhesion.

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...
