    Abstract: A display panel and a display device are disclosed. The display panel includes a first substrate, a second substrate, and a liquid crystal layer disposed therebetween. The first substrate includes a first base and a planarization layer disposed on a side of the first substrate adjacent to the liquid crystal layer. A side of the planarization layer adjacent to the liquid crystal layer includes a textured structure, which includes at least one groove path. The first substrate further includes a bottom edge. An extending direction of the at least one groove path forms an included angle with the bottom edge, the included angle being greater than or equal to 45 degrees and less than or equal to 135 degrees. A liquid crystal material in the liquid crystal layer diffuses along the extending direction of the groove path through the groove path based on capillary phenomenon.

    Abstract: A gate drive circuit includes a charging circuit, a first shutdown circuit and a second shutdown circuit, and a first startup circuit and a second startup circuit. The charging circuit includes an energy storage element, a first switch unit and a second switch unit. The energy storage element switches between charging and discharging states based on control signals responded by control terminals of the first switch unit and the second switch unit. Control terminals of the first shutdown/startup circuit and second shutdown/startup circuit respond to the shutdown/startup control signal when the energy storage element is in the discharging state so that output terminals of the first shutdown/startup circuit and the second shutdown/startup circuit output two shutdown/startup signals to the sub-pixel.

    Abstract: A pixel driving circuit, a method thereof, and a display panel, related to the field of display technology. The pixel driving circuit includes: a first charging unit, a discharging unit, a second charging unit, an energy storage capacitor and a driving transistor. The first charging unit is configured for pre-charging the energy storage capacitor. The discharge unit is configured for discharging the voltage of the pre-charged energy storage capacitor to a preset voltage. The second charging unit is configured for inputting the data voltage to the storage capacitor. After the second charging unit charges the energy storage capacitor, the voltage of the energy storage capacitor is equal to the sum of the preset voltage and the data voltage. The energy storage capacitor is connected to the gate electrode of the driving transistor.

    Abstract: Provided are an array substrate and a display panel. The array substrate includes: a base and first leads and second leads disposed in a non-display area on the base, the first leads are electrically connected to pixel electrodes, the second leads are electrically connected to a common electrode or to a ground electrode, the array substrate further includes an electrically actuated component, a bottom surface of which is conductive. After the electrically actuated component changes from an energized state to a de-energized state, the bottom surface is deformed and contacts at least part of the first leads and at least part of the second leads. The pixel electrodes and the common electrode or the ground electrode are shorted as the bottom surface of the electrically actuated component contacts the first leads and the second leads, to release residual charge on the pixel electrode.
