摘要： A pixel circuit, a driving method, and a display device are provided. The pixel circuit includes a light emitting element, a driving circuit, a first energy storage circuit, a first setting circuit, a second setting circuit and a light emitting control circuit. The first setting circuit controls to connect the first setting voltage terminal and the first node under the control of the first control signal provided by the first control terminal; the second setting circuit controls to connect the second setting voltage terminal and the second terminal of the first energy storage circuit under the control of the second control signal provided by the second control terminal. The present disclosure may implement PWM control by adopting the light emitting control circuit.

摘要： An array substrate and a display device. The array substrate (100) includes a base substrate (110), a first electrode (120), a first insulating layer (130) and a second electrode (140). The first electrode (120) is on the base substrate (110); the first insulating layer (130) is on a side of the first electrode (120) away from the base substrate (110); the second electrode (140) is on a side of the first insulating layer (130) away from the first electrode (120). The second electrode (140) is provided with a first through-hole (141) and a slit (142) communicated with the first through-hole (141) and extending from the first through-hole (141) to an edge of the second electrode (140), and an orthographic projection of the first electrode (120) on the base substrate (110) completely falls within an orthographic projection of the second electrode (140), the first through-hole (141) and the slit (142) on the base substrate (110). At this time, the first electrode (120), the second electrode (140), and the first insulating layer (130) can constitute a capacitor (Cst). The array substrate can ensure that the actual capacitance value of the capacitor is consistent with the design value when the alignment deviation occurs, thereby improving the yield of the display device using the array substrate.
