Abstract: A display panel includes a drive backplane, a transparent insulating layer and a light-emitting device layer. The drive backplane includes a driving circuit layer, a metal wiring layer, a first insulating layer and a reflective electrode layer. The first insulating layer has first via holes filled with first metal connectors. The reflective electrode layer includes first reflective electrodes respectively connected with the metal wiring layer through the first metal connectors. The light-emitting device layer includes a pixel electrode layer, an organic light-emitting layer and a common electrode layer. The pixel electrode layer includes first pixel electrodes respectively connected with the first reflective electrodes through the connection via holes. A distance between an orthographic projection of the connection via hole on the pixel electrode layer and an edge of the first pixel electrode is not less than a first threshold value.

Abstract: A silicon-based OLED display substrate, a manufacturing method thereof and a display device are provided. The display substrate includes: a silicon-based base and a device layer arranged on the silicon-based base. The silicon-based base includes a drive circuit layer. The drive circuit layer includes a drive circuit, an electrical connection bonding area, and a storage unit storing compensation voltage of each MOSFET of the drive circuit. An orthographic projection of the drive circuit on the silicon-based base, an orthographic projection of the storage unit on the silicon-based base, and an orthographic projection of the electrical connection binding area on the silicon-based base do not overlap with each other.

Abstract: A display panel is provided. The display panel includes a driving back plate and a pixel layer disposed on a side of the driving back plate. The pixel layer includes a plurality of pixels, and the pixel includes m color sub-pixels for emitting color light and k white sub-pixels for emitting white light, wherein m and k are both integers greater than 1. The k white sub-pixels are configured to adjust the luminance of the pixel.
