A light-emitting device and an OLED display panel are provided. The light-emitting device includes a charge generation layer. The charge generation layer includes an N-type electron generation layer, a P-type hole generation layer, and a metal activation layer disposed between the two. The metal activation layer is in surface contact with of the N-type electron generation layer and the P-type hole generation layer. It activates a surface energy at contact surfaces, prevents an accumulation of charges to form an electric field in an internal space, and improves a performance and a lifespan of the light-emitting device.

Light-emitting device and OLED display panel

A display panel and an electronic device are provided. The display panel includes a first panel, a second panel, and a binding layer. The first panel includes light-emitting units, and also includes light-transmitting regions. The second panel includes photoelectric sensing elements and a second driving circuit layer. The second driving circuit layer includes second driving transistors. The second driving transistors are electrically connected to the photoelectric sensing elements, and the photoelectric sensing elements are opposite to the light-transmitting regions. The binding layer is disposed between the first panel and the second panel, and configure to bind the first panel and the second panel.
