Abstract:
The present disclosure discloses a display compensation circuit and a method for controlling the same, and a display apparatus. The display compensation circuit comprises a pixel circuit and a power supply selection circuit. The pixel circuit comprises: a light-emitting control sub-circuit; a driving transistor; a first compensation sub-circuit; a second compensation sub-circuit; and a light-emitting element. The power supply selection circuit is coupled to the first power supply terminal, the second power supply terminal, a first switch control terminal, a second switch control terminal and the third node respectively, and is configured to selectively transmit a first power supply signal at the first power supply terminal and a second power supply signal at the second power supply terminal to the third node under control of the first switch control terminal and the second switch control terminal.
