Abstract: Embodiments of the present disclosure provide a pixel circuit, a driving method thereof, and a display panel. The pixel circuit comprises: a light-emitting element; a driving sub-circuit configured to generate a current for driving the light-emitting element to emit light; and a first and a second light emission controlling sub-circuit, configured to supply the current for driving the light-emitting element to emit light to a first terminal of the light-emitting element under a control of a first controlling signal, respectively; a driving controlling sub-circuit configured to provide a data signal to the driving sub-circuit under a control of a second controlling signal; and the resetting sub-circuit configured to reset the driving sub-circuit, the first terminal of the light-emitting element, and a second node with a first voltage, under a control of a first resetting signal and a second resetting signal.

Abstract: Provided are a display panel and a manufacturing method thereof and a display device. The display panel includes: a base substrate; a pixel defining layer including first openings defining sub-pixels; an encapsulation layer; and a light modulation layer. The light modulation layer is configured such that light from each of at least one sub-pixel propagates along a direction away from the base substrate after total reflection upon incidence on an interface between the first light modulation portion in a corresponding second opening and the first light modulation sub-layer. The display panel satisfies at least one of a first condition or a second condition. The first condition is that at least a part of edge of the first orthographic projection has a recess. The second condition is that at least a part of edge of the second orthogonal projection has at least one of a recess or a protrusion.

Abstract: A display substrate has an active area and a frame region located at at least one side of the active area. The display substrate includes a substrate, pixel units, at least one blocking dam and a first encapsulation layer. The pixel units is disposed on the substrate and located in the active area. The at least one blocking dam is disposed on the substrate and located in the frame area. The at least one blocking dam is provided with at least one groove on a surface thereof facing away from the substrate, a depth direction of the at least one groove is perpendicular to the substrate, and an extending direction of the at least one groove is substantially the same as an extending direction of the blocking dam provided with the at least one groove. The first encapsulation layer covers the at least one blocking dam.
