  • LIGHT-EMITTING DEVICE AND OLED DISPLAY PANEL
    Publication number: 20240040821
    Abstract: 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.
