  • OLED display and OLED display device with plurality of light-absorbing bodies in planarization layer
    Patent number: 10937995
    Abstract: An organic light emitting diode (OLED) display panel and an OLED display device include a substrate, a thin film transistor array function layer disposed on the substrate; a planarization layer disposed on the thin film transistor array function layer; an anode electrode disposed on the planarization layer; and a pixel definition layer disposed on the anode electrode. The planarization layer and/or the pixel definition layer include a plurality of light-absorbing bodies used for absorbing incident light emitted from outside the OLED display panel. The light-absorbing bodies are doped in the planarization layer and/or the pixel definition layer.
