    摘要: A pixel circuit, a driving method for same, and a display apparatus are provided. The pixel circuit includes a driving sub-circuit, a writing sub-circuit, a compensation sub-circuit, a first reset sub-circuit, an emitting element. The driving sub-circuit provides a driving current for a third node under control of signals of first and second nodes. The writing sub-circuit writes a signal of the data signal terminal into the second node under control of a signal of a second scanning signal terminal. The first reset sub-circuit writes an initial voltage signal of a first initial signal terminal into the third node under control of a first scanning signal terminal and a first emitting control signal terminal. The compensation sub-circuit writes the initial voltage signal of the third node into the first node under control of a third scanning signal terminal, compensates the first node under control of the third scanning signal terminal.

    摘要: A display substrate and a manufacturing method thereof, and a display device are disclosed. The display substrate includes a base substrate, lead wires, a plurality of contact pads, a first insulation laminated layer, and a second insulation laminated layer. The base substrate includes a display region, a dam region at least partially surrounding the display region, a transition region on a side of the dam region away from the display region, and a first bonding region and a bonding peripheral region on a side of the transition region away from the dam region. The plurality of contact pads is in the first bonding region and configured to be electrically connected to the lead wires. The first insulation laminated layer is in the first bonding region. The second insulation laminated layer is in the bonding peripheral region.
