Problems solved by technology

[0003] However, based on the current arrangement of the metal film layer in the display area, the area of ​​the light transmission area in the fingerprint identification area is very small, so that when fingerprint identification is performed, the amount of light reflected into the fingerprint identification area by the touch body is less , leading to low detection accuracy of fingerprint recognition

Abstract

Embodiments of the present invention provide a display panel and a display device, which relate to the field of display technology, and increase the area of ​​the area through which light passes in the fingerprint identification area, thereby improving the accuracy of fingerprint identification. The display panel includes: gate lines and data lines, which define sub-pixel areas; the sub-pixel areas include pixel circuits and light-emitting elements, and the light-emitting elements include anodes; light-emitting control signal lines and power signal lines; light-emitting control signal lines and The power signal line defines the sub-pixel area into the main light-transmitting area and the non-main light-transmitting area; the pixel circuit is located in the non-main light-transmitting area; the display area also includes the fingerprint identification area, and the shape of the anode in the fingerprint identification area is parallel to the opposite side. Approximate quadrilateral, at least one set of opposite sides of the anode has an included angle α with the row direction, 0°<α<90°. The above-mentioned display panel is used to realize screen display.

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] For the display panel with fingerprint recognition function, in order to better realize the full screen design and avoid the fingerprint recognition area occupying the space of the non-display area, the display area can be reused as the fingerprint recognition area by using the under-screen fingerprint technology. [0003] However, based on the current arrangement of the metal film layer in the display area, the area of ​​the light transmission area in the fingerprint identification area is very small, so that when fingerprint identification is performed, the amount of light reflected into the fingerprint identification area by the touch body is less , leading to low detection accuracy of fingerprint recognition. 【Content of invention】 [0004] In view of this, the embodiments of the present inven...
