Abstract: The present disclosure provides an organic light-emitting diode display substrate and a manufacturing method thereof. The manufacturing method includes: sequentially forming a first electrode, a light-emitting layer and a second electrode on a base substrate; forming a protection layer having a first opening on a side of the second electrode distal to the base substrate; and forming a second opening in the second electrode, the second opening being located below the first opening. In the present disclosure, with the protection layer, only a portion of the second electrode below the first opening is removed, so that other portions of the second electrode are prevented from being damaged, thereby eliminating a poor display of the display device.

Abstract: A display panel is disclosed. The display panel includes a flexible substrate; a display sub-region on the flexible substrate including a light emitting device; a peripheral region of the display sub-region spacing the display sub-region from an adjacent display sub-region; and a current compensator in the peripheral region for compensating a current flowing through the light emitting device of the display sub-region in response to deformation of the flexible substrate.

Abstract: A display substrate having a display area and a gate-on-array (GOA) area outside the display area is provided. The display substrate includes a base substrate; a light shielding layer on the base substrate; an insulating layer on a side of the light shielding layer away from the base substrate; and a GOA signal line on a side of the insulating layer away from the light shielding layer, and is connected electrically in parallel with a first part of the light shielding layer, the first part being in the GOA area. The display substrate includes a plurality of first vias extending through the insulating layer in the GOA area. The GOA signal line is electrically connected to the first part of the light shielding layer through the plurality of first vias respectively, thereby connecting the GOA signal line and the first part of the light shielding layer electrically in parallel.

Abstract: The present disclosure discloses a display panel and a detecting method thereof. By providing at least one resistance sensor in a bending region, an extending direction of the resistance sensor is perpendicular to an extending direction of an axis for bending and overlaps with the axis for bending. By electrically connecting the resistance sensor to a detecting circuit, a change of the resistance value of the resistance sensor can be reflected as a change of voltage.
