Problems solved by technology

[0003] However, in the fingerprint identification panel in the prior art, the fingerprint identification unit is arranged in the gap between a plurality of pixel units in the display panel, and as the display panel develops towards high resolution, the pixel unit The gap is getting smaller and smaller. If the fingerprint recognition unit is set in the gap, it will affect the pixel density of the display panel. If the number of fingerprint recognition units is reduced, the sensitivity of the fingerprint recognition unit will be affected, so it is difficult to achieve a better Fingerprint recognition effect

Abstract

The invention provides a display panel, a manufacturing method thereof and a display device, whichbelong to the technical field of display. The display panel comprises a substrate, a plurality of light emitting devices and a plurality of fingerprint identification units,wherein the plurality of light-emitting devices are arranged at one side of the substrate, the plurality of fingerprint identification units are arranged at one side, deviating from the substrate, of the lightemitting device located in the fingerprint identification area, and at least one fingerprint identification unit and onelightemitting device located in the fingerprint identification area are arranged in a stacked mode. The fingerprint identification unit in the display panel provided by the invention does not need tooccupy extra space of the layer where the lightemitting device is located, so that the fingerprint identification unit can be prevented from influencing the resolution of the display panel, and the fingerprint identification unit can be prevented from influencing the lightemitting rate of the lightemitting device.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, the display panel with fingerprint identification function has become the mainstream. Usually, a fingerprint identification unit is arranged in the fingerprint identification area of ​​the display panel, and fingerprint identification is realized according to the change of the light intensity received by the fingerprint identification unit. [0003] However, in the fingerprint identification panel in the prior art, the fingerprint identification unit is arranged in the gap between a plurality of pixel units in the display panel, and as the display panel develops towards high resolution, the pixel unit The gap is getting smaller and smaller. If the fingerprint recognition unit is set in the gap, it will affect the pixel densi...
