Title:
ELECTROLUMINESCENT UNIT, DISPLAY PANEL, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/257951
Kind Code:
A1
Abstract:
The present application discloses an electroluminescent unit, a display panel, and an electronic device, applied to an under-screen camera region. The electroluminescent unit comprises: a transparent cathode, the transparent cathode being configured to be connected to a circuit negative electrode of the electroluminescent unit and emitting light from the electroluminescent unit; an anode, the anode being configured to be connected a circuit positive electrode of the electroluminescent unit; and at least two laminated pixel light-emitting units located between the transparent cathode and the anode, the pixel light-emitting units each comprising a pixel light-emitting layer, an electron function layer provided at one side of the pixel light-emitting layer, and a hole function layer provided at the other side of the pixel light-emitting layer. The electroluminescent unit further comprises a connection layer provided between two adjacent pixel light-emitting units; the connection layer has one side provided with the electron function layer, and the other side provided with the hole function layer; and the connection layer is used for providing electrons to the electron function layer and used for providing holes to the hole function layer.
