Patent ID: 11468840

Abstract:
Embodiments of the present disclosure provide a driving backplane and a display panel. The driving backplane has a plurality of sub-pixel regions, and includes: a base; a plurality of pixel driving circuits disposed on the base, one of the plurality of pixel driving circuits being disposed in one of the plurality of sub-pixel regions; and a plurality of data lines and a plurality of first power supply voltage lines disposed on the base. The pixel driving circuit is electrically connected to a data line and a first power supply voltage line. The data line and the first power supply voltage line are disposed on a side, away from the base, of the pixel driving circuit, and the data line and the first power supply voltage line are disposed at intervals in a same layer. An orthographic projection of the data line on the base overlaps with an orthographic projection of the pixel driving circuit on the base. The pixel driving circuit includes a driving transistor, a first switching transistor, and a first conductive pattern. The first conductive pattern is located on a side, away from the base, of the driving transistor and the first switching transistor. The first conductive pattern is electrically connected to a gate of the driving transistor through a first via. The first conductive pattern is electrically connected to a second electrode of the first switching transistor through a second via. An orthographic projection of the first conductive pattern on the base is located within an orthographic projection of the first power supply voltage line on the base.
