  • Publication number: 20240130155
    Abstract: Embodiments provide a display device that includes a substrate, a transistor disposed on the substrate, and a light emitting device that is electrically connected to the transistor. The light emitting device includes a first electrode that is electrically connected to the transistor, a second electrode disposed on the first electrode, a light emitting layer disposed between the first electrode and the second electrode, a hole transport layer disposed between the first electrode and the light emitting layer, and an electron blocking layer disposed between the hole transport layer and the light emitting layer. Mobility of the hole transport layer is equal to or less than about 2.0*10?3 cm2/(Vs), and a real part of impedance of the light emitting device is equal to or less than about 100?, in a frequency range of about 105 Hz to about 106 Hz.

  • Patent number: 11943945
    Abstract: An organic light-emitting diode (“OLED”) includes a bottom electrode, a top electrode disposed opposite to the bottom electrode, and an organic layer that is interposed between the bottom electrode and the top electrode and includes a hole-transporting host and an electron-transporting host forming an exciplex and a phosphorescent dopant having a triplet energy which is lower than the triplet energy of the hole-transporting host, the triplet energy of the electron-transporting host, and the triplet energy of the exciplex, and a lighting device and a display apparatus including the OLED. Instead of a phosphorescent dopant, the fluorescent dopant having a singlet energy which is lower than the singlet energy of the exciplex may be also used.
