    Abstract: An organic light-emitting diode (OLED) display substrate, a manufacturing method thereof and a display panel are provided. The OLED display substrate has pixel regions and includes a base substrate and a pixel defining layer disposed on the base substrate; in regions of the pixel defining layer corresponding to the pixel regions, accommodation parts penetrating the pixel defining layer are disposed, and the pixel defining layer is further provided with guide parts disposed corresponding to the accommodation parts, the guide parts are located on a periphery of the corresponding accommodation parts and formed by recessed areas which are formed on a side of the pixel defining layer away from the base substrate, the recessed areas do not penetrate the pixel defining layer, and an orthographic projection of the guide part on the base substrate is directly coupled to an orthographic projection of the corresponding accommodation part on the base substrate.

    Abstract: A display panel includes a substrate, an auxiliary electrode, a connection portion, a light-emitting layer and a cathode layer. The connection portion includes a first connection pattern connected to the auxiliary electrode, a second connection pattern, and a third connection pattern that are sequentially stacked. An edge of the second connection pattern is indented inward relative to an edge of the third connection pattern. The light-emitting layer includes a first light-emitting pattern and a second light-emitting pattern. The first light-emitting pattern is located around and separated from the second light-emitting pattern. The second light-emitting pattern is located on a side of the third connection pattern away from the substrate. The cathode layer passes through a gap between the first light-emitting pattern and the second light-emitting pattern to be in electrical contact with the at least one of the first connection pattern, the second connection pattern and the third connection pattern.

    Abstract: A shift-register unit includes a first circuit including a first input circuit coupled via a first node to a first output circuit, and a second circuit including a second input circuit coupled via a second node to a second output circuit. The first input circuit is configured to control a voltage level of the first node in response to a first input signal. The first output circuit is configured to output a shift-register signal and a first output signal in response to the voltage level of the first node. The second input circuit is configured to control a voltage level of the second node in response to the first input signal. The second output circuit is configured to output a second output signal in response to the voltage level of the second node. The first input circuit and the second input circuit have a same circuit structure.
