A display panel and a mobile terminal are disclosed. The display panel includes a gate driving circuit, the gate driving circuit includes a first driving transistor and a second driving transistor disposed along a second direction, the first driving transistor includes a first source and a first drain, the second driving transistor includes a second source and a second drain, the first source and the second source are connected to a same control node. The first source, the first drain, the second source and the second drain are disposed side by side along the first direction, the first source and the second source are disposed between the first drain and the second drain, and the first source and the second source at least partially overlap in the second direction.

Display panels and mobile terminals

A display panel and a display module are provided. The display panel includes a non-display area, a central display area, and a peripheral display area arranged between the two areas. A counterpart substrate is arranged opposite to an array substrate, with a liquid crystal layer positioned between the array substrate and the counterpart substrate. A meta-surface structure layer of the counterpart substrate is arranged in the peripheral display area. Light emitted from the peripheral display area is at least partially deflected by the meta-surface structure layer and then emerges from the non-display area. The meta-surface structure layer in the peripheral display area alters the propagation path of light, allowing at least part of the light emitted from the peripheral display area to enter the non-display area. This approach overcomes the limitations imposed by a frame, enlarges the display area of the display panel, and achieves a narrow-frame display panel.

Display panel and display module having meta structure layer in peripheral display area

A display panel and a display device. The display panel includes a first substrate, a second substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. The first substrate includes a driving circuit layer. The driving circuit layer includes a light-shielding portion and a plurality of light-transmitting portions. The second substrate includes a light-shielding layer. The light-shielding layer includes a body portion and a plurality of hollow portions. The body portion is disposed corresponding to the light-shielding portion. The hollow portions are disposed corresponding to the light-transmitting portions. The first substrate further includes a refractive layer disposed on a side of the light-shielding portion away from the liquid crystal layer, or the second substrate further includes a refractive layer disposed on a side of the body portion away from the liquid crystal layer.

Display panel and display device

A gate driving circuit including cascaded gate driving units is provided. A gate driving unit includes a pull-up control module, a pull-up module electrically connected to the pull-up control module through a first node, a pull-down maintaining module electrically connected to the first node and a voltage line, and a voltage control module. An input terminal of the pull-up module loads a clock signal, and an output terminal is electrically connected to a gate line. The pull-down maintaining module is electrically connected to the pull-up module through the first node and includes an inverter module. The voltage control module is electrically connected to an output terminal of the inverter module to control a first transition edge of a signal at the output terminal of the inverter module to lag behind a second transition edge of the clock signal within a duration of a corresponding clock pulse of the clock signal.
