    摘要: The embodiments of the present invention provide an organic light emitting diode device, display panel and display device. The existing top emitting series OLED device is improved with a structure of homojunctions; the functional layer of the top emitting series OLED device is also improved. The functional layer comprises a hole injection layer, a hole transport layer, a plurality of light emitting layers, an electron transport layer and an electron injection layer sequentially arranged from the anode. A charge generation layer A and a charge generation layer B are arranged between two directly adjacent light emitting layers. A homojunction is applied in each light emitting unit of the top emitting series OLED device, reducing the types of organic materials and the carrier injection barrier, improving the injection of carriers and the efficiency of the device. The driving voltage of the device is thus reduced.

    摘要: An organic light emitting diode display device and a display apparatus, and a mask for fabricating a sub-pixel of the organic light emitting diode display device are provided. Each pixel unit group includes a first sub-pixel unit group and a second sub-pixel unit group which are disposed adjacently along a first direction and include three sub-pixels of different colors, respectively; and the three sub-pixels in the first sub-pixel unit group and the three sub-pixels in the second sub-pixel unit group are staggered along a second direction, and a color of any sub-pixel on a base substrate 10 is different from a color of any other sub-pixel adjacent to the sub-pixel. The organic light emitting diode display device ensures that the sub-pixels of a same color are staggered regularly on the base substrate, which increases strength of the mask, and is conducive to fabrication of the sub-pixel of a small size, so that the resolution of the organic light emitting diode display device can be improved.

    摘要: An OLED device comprises an anode, a hole transport layer, an electro-luminescence layer, an electron transport layer and a cathode, which are superposed successively. A hole-side exciton utilization layer for allowing holes to freely pass therethrough is provided between the hole transport layer and the electro-luminescence layer, and/or an electron-side exciton utilization layer for allowing electrons to freely pass therethrough is provided between the electron transport layer and the electro-luminescence layer. Hole-side electro-luminescence material is doped in the hole-side exciton utilization layer, and the energy level of the hole-side electro-luminescence material is lower than that of material of the hole transport layer. Electron-side electro-luminescence material is doped in the electron-side exciton utilization layer, and the energy level of the electron-side electro-luminescence material is lower than that of material of the electron transport layer.
