Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel comprises a display area and a non-display area at least partially surrounding the display area; the display area comprises a fingerprint identification area, the fingerprint identification area comprises a plurality of sub-areas arranged in an array, and each sub-area comprises at least one fingerprint identification circuit; the fingerprint identification circuit comprises at least one fingerprint identification sensor, a plurality of signal lines and a plurality of circuit elements; and each sub-area is provided with a central area and a peripheral area, at least one part of the fingerprint identification sensor is located in the central area, and the circuit elements and at least parts of the signal lines are located in the peripheral area. The signal lines in the fingerprint identification circuit are intensively arranged in the peripheral area, and the fingerprint identification sensors are intensively arranged in the central area so that the effective area of each fingerprint identification sensor can be maximized, and the light incoming amount of the fingerprint identification sensors and the fingerprint identification precision are improved; and meanwhile, the short-circuit risk of the display panel is also reduced.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display panels have characteristics such as self-illumination, high contrast ratio, thinness, and power saving, and thus are widely used in various smart terminal devices. [0003] In recent years, with the rise of full-screen technology, it has become a trend to integrate fingerprint identification in the display area of ​​the display device. Usually, the fingerprint identification area includes a fingerprint identification circuit, and the fingerprint identification circuit includes a fingerprint identification sensor and a plurality of signal lines electrically connected to the fingerprint identification sensor. For a display device using optical fingerprint recognition technology, when performing fingerprint recognition, the light emitted by the fingerpri...
