A pixel circuit is provided. A first terminal and a second terminal of a light-emitting sub-circuit are coupled to a first power supply terminal and a compensation sub-circuit respectively. A short-circuiting sub-circuit is coupled to the first terminal and the second terminal of, and short-circuits under control of a short-circuiting control terminal, the light-emitting sub-circuit. The compensation sub-circuit is coupled to a data voltage terminal, a reference voltage terminal, and a first electrode and a gate electrode of a driving transistor. The light-emitting sub-circuit emits a light of brightness in a level corresponding to a current flowing therethrough. The compensation sub-circuit loads, based on the data voltage terminal and the reference voltage terminal, a driving voltage related to a threshold voltage of the driving transistor onto the gate electrode of the driving transistor, such that a current flowing through the driving transistor is not influenced by its threshold voltage.

Pixel circuit, driving method thereof, and display apparatus

An organic light-emitting diode (OLED) array substrate, a display apparatus and a method for repairing a dark spot of the display apparatus or the OLED array substrate are provided by the embodiments of the present disclosure. The OLED array substrate includes: power lines, a connection component, a pixel structure disposed in a pixel region, and the pixel structure includes a driving transistor, and an OLED device. The OLED device includes a first electrode and a second electrode, and the first electrode is electrically connected with the first source/drain electrode of the driving transistor; the connection component is configured to electrically insulating the first electrode from the power lines before repairing the OLED array substrate; and the connection component is further configured to electrically connect the first electrode (anode or cathode) with the power lines in a case of repairing the OLED array substrate.
