Abstract: The present application provides a displaying base plate and a displaying device, which relates to the technical field of displaying. The displaying device can ameliorate the problem of screen greening caused by electrostatic charges, thereby improving the effect of displaying. The displaying base plate includes an active area and a non-active area connected to the active area, the non-active area includes an edge region and a first-dam region, and the first-dam region is located between the active area and the edge region; the displaying base plate further includes: a substrate; an anti-static layer disposed on the substrate, wherein the anti-static layer is located at least within the edge region; and a driving unit and a touch unit that are disposed on the substrate, wherein the driving unit is located within the active area.

Abstract: Provided are a display substrate, a testing method therefor and a preparation method therefor, and a display panel, which are used for improving the success rate of transistor testing. The display substrate comprises a base substrate and a pixel circuit, wherein the pixel circuit comprises an active layer, a first gate insulating layer, a first gate electrode layer, a second gate insulating layer, a second gate electrode layer, a first interlayer insulating layer, a source/drain electrode layer, and a second interlayer insulating layer. The pixel circuit is divided into a plurality of transistors, and further comprises a gate electrode contact hole and a source/drain electrode contact hole.

Abstract: The present disclosure provides a display substrate, including: a base substrate having an opening region, a transition region surrounding the opening region and a pixel region surrounding the opening region; at least one ink-jet printing dam in the transition region and surrounding the opening region; and at least one conductive film layer in the transition region, where an orthographic projection of the conductive film layer on the base substrate is overlapped with an orthographic projection of the ink-jet printing dam on the base substrate. In the technical solution of the present disclosure, the conductive film layer is intended to absorb and conduct heat, so as to reduce the heat on the ink-jet printing dam.

Abstract: A display panel includes a substrate, a plurality of data lines, at least one circle of barrier wall structure, and a connector. The substrate includes a display area, and a peripheral area which surrounds the display area and includes a fan-out area. The plurality of data lines are located on one side of the substrate and in the display area, extending from the display area to the fan-out area. The at least one circle of barrier wall structure surrounds the display area, and at least a part of the at least one circle of barrier wall structure is located in the fan-out area. The connector is located between the plurality of data lines and the barrier wall structure, and one end, away from the substrate, of the connector extends into the barrier wall structure to fasten the barrier wall structure.
