Problems solved by technology

However, since the base substrate of the flexible display is usually a yellow polyimide material, the transmittance to blue light is low, which seriously affects the transmission of the reflected light of the fingerprint, resulting in the slow unlocking speed of the fingerprint recognition module.

Abstract

The invention provides a display panel and a display device, which relate to the field of display technology, wherein the display panel includes a display screen and a fingerprint identification module, the display screen includes a base substrate, a metal wire layer and a pixel definition layer, and the metal wire layer is located on the base substrate Between the pixel definition layer and the pixel definition layer, the fingerprint identification module is located on the side of the substrate away from the pixel definition layer; the metal wire layer has a light-transmitting area, and the pixel definition layer includes a light-emitting area and a non-light-emitting area, and at least part of the non-light-emitting area is set There is a light conversion layer, and the position of the light conversion layer corresponds to the position of the light transmission area. The display panel provided by the present invention improves the light intensity and transmittance of the incident light of the fingerprint so that it can pass through the display screen more accurately and efficiently to reach the fingerprint recognition module, thereby increasing the speed of fingerprint recognition and unlocking.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] When OLED full-screen display panels are applied to mobile terminals such as mobile phones, the effective display area is large, and the amount of information that can be displayed is large, thereby improving the human-computer interaction experience. Therefore, full-screen display panels are increasingly used in display devices. middle. While the existing display panel realizes a full display, in order to realize the fingerprint recognition function, it is necessary to integrate a fingerprint recognition module in the display area of ​​the full display. [0003] Usually, the fingerprint identification module is arranged under the display area. In the working state, the display screen emits light to the light-emitting elements outside the screen body, and then reflects to the screen body through the fin...
