Abstract
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 thin layer transistor (22), a first electrode (23′), a second electrode (26′) and an organic functional layer (25) located between the first electrode (23′) and the second electrode (26′). The thin film transistor (22) comprises a gate electrode (221), a source electrode (222) and a drain electrode (223); and the first electrode (23′) is electrically connected with the drain electrode (223). The display device further comprises a first auxiliary electrode (27) formed from a topological insulator. The first auxiliary electrode (27) is electrically connected with the second electrode (26′) to provide electrical signals for the second electrode (26′). The OLED display avoids the problems of high IR drop and non-uniform lightness caused by the large transmission resistance of the cathodes.
