Abstract: The present application provides a manufacturing method for a display substrate, a display substrate, and a display device. The uniformity of film thicknesses of light-emitting functional layers in sub-pixel regions of different colors can be achieved, the effective aperture ratio of the sub-pixel regions of different colors can be ensured, and the service life of the device can be prolonged. The manufacturing method comprises: providing a base substrate, the base substrate comprising a plurality of sub-pixel regions of different colors; printing a solution of a light-emitting functional layer in each sub-pixel region, wherein the volumes of the solution in the sub-pixel regions of different colors are positively correlated with the saturated vapor pressure of the solution; and performing vacuum drying on the solution to form light-emitting functional layers having uniform film thicknesses.

Abstract: The present application provides an organic light-emitting diode display device, comprising an anode layer, a cathode layer, and a first light-emitting layer and a second light-emitting layer which are provided between the anode layer and the cathode layer. The first light-emitting layer comprises a first light-emitting portion, a second light-emitting portion, and a third light-emitting portion which are arranged side by side. The second light-emitting layer is used for emitting light of the same color as that emitted from the first light-emitting portion. The organic light-emitting diode display device further comprises a charge generation layer provided between the second light-emitting layer and the first light-emitting portion.

Abstract: Embodiments of the present disclosure disclose a display apparatus, a manufacturing method for a display apparatus, and an electronic device. The display apparatus includes a first display region and a second display region which adjoin each other. A light transmittance of the second display region is smaller than a light transmittance of the first display region. The second display region includes a thin film transistor. A light shielding portion is disposed between the first display region and the second display region to shield the thin film transistor in the second display region from being irradiated by a light signal from the first display region.
