Abstract: A display substrate, a manufacturing method thereof, and a display device are provided. The display substrate includes a base substrate, organic light-emitting elements, a data line, and an electrode line. The organic light-emitting element includes a first electrode, a light-emitting layer and a second electrode sequentially stacked; the data line is located between the base substrate and the organic light-emitting element; the electrode line is on the same layer as the data line and located in a region outside a light-emitting region of the organic light-emitting element. The display substrate further includes at least one connection portion, which is in the region outside the light-emitting region and is configured to connect the electrode line and the first electrode, the connection portion is spaced apart from the second electrode, and the light-emitting layer covers the second electrode and the at least one connection portion.

Abstract: A grid-driving-circuit array is applied to a display panel, the display panel is delimited into a plurality of active areas, and each of the active areas includes multiple rows of pixel units and multiple rows of grid lines. The multiple groups of grid driving units supply grid driving signals to the plurality of active areas, and each of the groups of grid driving units includes one or more grid driving circuits. The one or more grid driving circuits are configured for supplying the grid driving signals to the grid lines within the active area corresponding to the one or more grid driving circuits. One or more multiplexers, wherein each of the multiplexers includes a plurality of frame-starting-up-signal outputting units, each of the frame-starting-up-signal outputting units of the multiplexer is configured for supplying a frame starting-up signal to one of the grid driving circuits.
