Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device, and relates to the technical field of display. The display panel comprises a substrate, an array layer which is located on the side, facing the light emitting face of the display panel, of the substrate; a light-emitting device layer which is located on the side, facing the light-emitting face of the display panel, of the array layer and comprises a plurality of organic light-emitting devices, wherein each organic light-emitting device comprises an anode, a light-emitting layer and a cathode which aresequentially arranged, and the cathodes are located on the sides, away from the substrate, of the anodes; a cathode connecting part located in the non-light-emitting area, wherein the cathode is electrically connected through the cathode connecting part; a fingerprint recognition assembly which comprises a plurality of fingerprint recognition sensors, wherein the fingerprint recognition sensors are located on the side, facing the substrate, of the cathode, the orthographic projection of the fingerprint recognition sensors on the plane where the substrate is located is at least partially overlapped with the cathode connecting part, and the transmittance of the cathode connecting part is larger than that of the cathode. Therefore, the fingerprint recognition sensitivity of the display module and the display device is improved, and the experience effect of a user is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Human fingerprints are unique and non-deformable, which makes fingerprint recognition more secure. At the same time, because of its simple operation, it is widely used in various fields, for example, the field of display technology. In the field of display technology, taking a mobile phone as an example, when unlocking or opening a specific application, it can be done through fingerprint recognition. [0003] With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. In this way, before operating the display device with fingerprint recognition function, the user only needs to touch the fingerprint recognition module of the displ...
