Patent attributes
An organic light emitting diode (OLED) display device and a preparation method thereof, and a display apparatus are disclosed. The OLED display device includes a base substrate (21), an anode (23), a cathode (26) and an organic functional layer (25), the anode (23), the cathode (26) and the organic functional layer (25) formed on the base substrate (21), and the organic functional layer (25) located between the cathode (26) and the anode (23), the anode (23) and/or the cathode (26) being a topological insulator with a two-dimensional nanostructure, and the topological insulator with the two-dimensional nanostructure being adhered on the base substrate (21) by an adhesive layer. The OLED display device overcomes the problem of non-uniform display lightness which is caused by the high transmission resistance and high IR drop of metal electrodes of OLED display devices.
