Abstract: A display panel and a display device are provided. The display panel includes a transistor, and the transistor includes an active layer extending in a second direction and a gate layer located on one side of the active layer. The gate layer includes a main stem portion extending in a first direction and a branch portion extending from a side of the main stem portion. In a top view, the active layer overlaps the main stem portion and the branch portion to realize a multiple gate design, optimize layout of the transistor, and facilitate increasing an aperture ratio of a pixel and realizing a sensing integration design.

Abstract: A display panel, a pixel driving circuit, and a display device are provided. Driving transistors include a first transistor and a second transistor connected in parallel. An absolute value of a threshold voltage of the first transistor is greater than an absolute value of a threshold voltage of the second transistor. A carrier mobility of the first transistor is greater than a carrier mobility of the second transistor. A driving current is affected by characteristics of the second transistor and an increase speed is slowed down, which improves a problem of color unevenness of the display panel at low brightness.

Abstract: A display panel and a display device are provided. The display panel includes an active layer, a gate electrode layer, and a metal layer. By forcibly pulling down an electrical potential of a scan signal in a first scan line when a pulse rising edge of the scan signal in the second scanning line arrives, an electrical potential falling time of each scan signal in a display area can be shortened. At the same time, a control line is constructed to at least partially overlaps an electrical potential transmission line in a thickness direction of the display panel, to increase an aperture ratio as much as possible.

Abstract: The present invention discloses a display panel and an electronic terminal. The display panel includes a first display region and a second display region. The second display region includes a plurality of display subregions. Each of the plurality of display subregions includes a display portion and a light-transmitting portion. Each of the plurality of display subregions includes a switch control unit, a liquid crystal layer, a transparent electrode group, and a color filter layer. The liquid crystal layer is disposed in the display portion and the light-transmitting portion. The transparent electrode group is configured to control a deflection direction of liquid crystal molecules in the liquid crystal layer, which puts the light-transmitting portion in a light-transmitting state or an opaque state.
