Abstract: An OLED array substrate is provided. The OLED array includes multiple sub-pixels defined by multiple data lines and multiple scan lines, and a resistance-type pressure sensing element located in non-opening regions of the sub-pixels. The pressure sensing element includes multiple resistors. Each resistor has a serpentine wire structure. The serpentine wire structure includes a first sub-wire and a second sub-wire connected to two adjacent first sub-wires. Both the first sub-wire and the second sub-wire are located in non-opening regions of the sub-pixels on the OLED array substrate. The resistance-type pressure sensing element is arranged in a display region of the OLED array substrate without influencing the display effect of a display panel or a display device. An extension direction of a projection of the first sub-wire on an array substrate intersects with extension directions of projections of the data lines and the scan lines on the array substrate.

The display panel includes: a light-shielding layer including imaging apertures, a light-emitting element layer including first light-emitting elements and second light-emitting elements, a touch functional layer, and a fingerprint recognition module. The orthographic projection of the second light-emitting element on the light-shielding layer is closer to the corresponding imaging aperture than the orthographic projection of the first light-emitting element on the light-shielding layer. In a first detection stage, the first light-emitting elements emit light, the second light-emitting elements do not emit light, and the fingerprint recognition module generates a first fingerprint image. In a second detection stage, the second light-emitting elements emit light, and the fingerprint recognition module generates a second fingerprint image. The first fingerprint image and the second fingerprint image are combined into a fingerprint image.
