摘要： A display substrate and a display apparatus. The display substrate comprises: a base and a circuit structure layer arranged thereon. The circuit structure layer comprises pixel circuits (P), a scan driving circuit, a control driving circuit and a buffer driving circuit. Each pixel circuit (P) comprises: a node reset transistor (T1), a write-in transistor (T4), a reset signal line (RL), a scan signal line (GL) and a control signal line (SL), the reset signal line (RL) being connected to a control electrode of the node reset transistor (T1), and the scan signal line (GL) being connected to a control electrode of the write-in transistor (T4). The reset signal lines (RL1-RLK) of the pixel circuits (P) in first to Kth rows are electrically connected to the buffer driving circuit, and the reset signal lines (RLK+1-RLN) of the pixel circuits (P) in (K+1)th to Nth rows are electrically connected to the scan driving circuit or the control driving circuit, K allowing, of a pixel circuit (P), a difference between the start time of an active level of a signal on the scan signal line (GL) or on the control signal line (SL) and the end time of an active level of a signal on the reset signal line (RL) to be greater than or equal to a threshold time.

摘要： A display substrate and a display apparatus. The display substrate comprises a display area and a peripheral area. The display substrate comprises a plurality of sub-pixels, which are located on a base substrate. At least some of the sub-pixels which are located in the display area comprise light-emitting elements and pixel circuits. Each light-emitting element comprises a light-emitting functional layer, and a first electrode and a second electrode, which are located on two sides of the light-emitting functional layer in a direction perpendicular to the base substrate, wherein the first electrode is located between the light-emitting functional layer and the base substrate. Each pixel circuit comprises a drive transistor and a light emission control transistor, wherein the first electrode of the light-emitting element is electrically connected to the light emission control transistor. The display substrate further comprises a binding area, which is located in the peripheral area, wherein the binding area is located on a first side of the display area. In the same pixel circuit, a channel area of the light emission control transistor is located on the side of a channel area of the drive transistor that is away from the binding area. In the embodiments of the present disclosure, pixel circuits located in a display area are designed, thereby being conducive to reducing a lower frame of the display apparatus on the basis that a pixel space is fully utilized.

摘要： A display panel, comprising: a substrate (310), a circuit structure layer (20), a light-emitting structure layer and a plurality of conductive layers. The conductive layers are located between the circuit structure layer (20) and the light-emitting structure layer, and comprise a plurality of conductive wires. At least one of a plurality of second pixel driving circuits is electrically connected to at least one second light-emitting device by means of a conductive wire, and the at least one second pixel driving circuit is configured to drive the at least one second light-emitting device to emit light. There is an overlap between orthographic projections, on the substrate (310), of parts of conductive wires of at least two of the plurality of conductive layers, which parts extend in a first direction (D1).
