Abstract: Disclosed are a display panel, a driving method thereof and a display device. 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.

Abstract: Display panel and display apparatus are provided. The display panel includes a display layer and a touch control layer. The display layer includes pixel units each including a number of sub-pixels arranged as a matrix. The touch control layer includes a bridge layer, a touch control metal layer, and an insulation layer there-between. The touch control metal layer includes metal mesh units, corresponding to the pixel units. In the touch control metal layer, adjacent metal mesh units are not connected. The touch control layer also includes at least one first touch control electrode, each including multiple metal mesh units. Adjacent two metal mesh units of the multiple metal mesh units are electrically connected through a connection lead. The connection lead is disposed on the bridge layer and electrically connected to each of the adjacent two metal mesh units through a corresponding via hole in the insulation layer.

Abstract: A spatial light modulator (SLM) includes a first liquid crystal panel and a second liquid crystal panel that are oppositely configured, and a polarization adjustment part configured between the first liquid crystal panel and the second liquid crystal panel. An alignment direction of the first liquid crystal panel is parallel to an alignment direction of the second liquid crystal panel. The first liquid crystal panel is configured to perform a phase modulation on incident linear-polarized light. The polarization adjustment part is configured to rotate, by a preset angle, a polarization direction of linear-polarized light exited from the first liquid crystal panel. The second liquid crystal panel is configured to adjust a polarization state of linear-polarized light exited from the polarization adjustment part to adjust an amplitude of exited light.

Abstract: Display panel and display device are provided. The display panel includes fingerprint recognition units, a substrate, drive circuits, and organic light-emitting units. A distance between two adjacent drive circuits in a drive circuit group is less than a distance between two adjacent drive circuits in two adjacent drive circuit groups along a first direction. The drive circuits from a first row to an i-th row is a first drive circuit, and the drive circuits from a j-th row to an M-th row is a second drive circuit. A first direction component, along the first direction, of each of vias that correspond to at least a portion of the first drive circuit pointing to a corresponding electrically-connected anode, and a second direction component, along the first direction, of each of vias that correspond to at least a portion of the second drive circuit pointing a corresponding electrically-connected anode, are opposite components.

Abstract: A display panel and a display device are provided. The display panel includes a base substrate and a plurality of pixel units disposed on the base substrate. Each of the plurality of pixel units includes a drive thin film transistor, a switch thin film transistor, a reset thin film transistor, and an organic light-emitting device. For each of the switch thin film transistor and the reset thin film transistor, in a direction perpendicular to a plane of the base substrate, a source and a drain are respectively located at two sides of a gate. The drain of the switch thin film transistor is electrically connected to a gate of the drive thin film transistor, and the drain of the reset thin film transistor is electrically connected to a drain of the drive thin film transistor. The drain of the drive thin film transistor is coupled to the organic light-emitting device.
