    摘要: Provided are a pixel circuit, a display apparatus and a driving method. In one type of pixel circuit, a first switch transistor is arranged between a gate electrode of a driving transistor and a second electrode of a first reset transistor, such that a leak current of the first reset transistor has a relatively small influence on a gate signal of the driving transistor. In other types of pixel circuit, a second reset transistor for short-circuiting the gate electrode and a first electrode is provided, such that the resetting of an anode of a light-emitting device is only related to a signal of a second reset signal end. Therefore, the voltage difference between two ends of a third reset transistor can be reduced by means of adjusting a signal voltage of a reference voltage signal end.

    摘要: The present application provides a display substrate, a display panel and a spliced screen, and belongs to the field of display technology. The display substrate in the present application is divided into display and boding regions, and includes a base substrate, and a pixel driving circuit on the base substrate and corresponding to the display region, The display substrate further includes an interlayer insulating layer and a signal lead-in wire on the base substrate. The signal lead-in wire at least includes a first signal lead-in sub-wire on a side of the interlayer insulating layer away from the base substrate. The first signal lead-in sub-wire is connected to a first connection pad in the bonding region for introducing an external signal to the pixel driving circuit. The interlayer insulating layer includes sub-insulating layers defining a multi-stepped structure at a position where the display region is adjacent to the bonding region.
