Abstract

The application relates to the technical field of display, in particular to a fingerprint operation prompting method, a display panel and a display device, in order to solve the problem in the prior art that there will be ghost shadow in the in-display fingerprint identification area due to long-time display of the same static graph. The method comprises the following steps: detecting whether a display device receives a fingerprint recognition instruction; and when a fingerprint recognition instruction for the display device is detected, dynamically displaying a first image used to prompt fingerprint operation in a preset target area, wherein the preset target area is within the display area of the display device. Thus, the problem of ghost shadow caused by the fact that the light emittingsub pixels in the preset target area always display a static image can be avoided. Moreover, the light emission duration of the light emitting sub pixels is reduced to a certain extent, the aging problem of the light emitting sub pixels is alleviated, and the display quality is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a fingerprint operation prompting method, a display panel, and a display device. Background technique [0002] In the prior art display devices with fingerprints under the screen, since the fingerprint identification module is hidden under the screen, it is not convenient for users to find the corresponding fingerprint identification area in time to perform fingerprint identification operations. If the same static graphic is displayed for a long time, even if there is no need to prompt after the fingerprint identification operation is completed or the entire screen displays the picture normally, an afterimage will be left in the fingerprint identification area, thereby affecting the display device. display quality. Contents of the invention [0003] Embodiments of the present application provide a fingerprint operation prompt method, a display panel, and a display d...
