Abstract: Disclosed are a pixel circuit, a driving method thereof, and a display apparatus. The pixel circuit includes a driving sub-circuit, a writing sub-circuit, a compensation sub-circuit, a reset sub-circuit, and a light-emitting element, the driving sub-circuit provides a driving current to a third node in response to a control signal of a first node; the writing sub-circuit writes a signal of a data signal line to a second node in response to a control signal of a first scan signal line, the signal of the data signal line is a data voltage signal or a reset voltage signal; the compensation sub-circuit writes the reset voltage signal to the third node in response to a control signal of the first scan signal line; the compensation sub-circuit further compensates the first node in response to a control signal of the first scan signal line.

Abstract: A device for separating cards in single sheet includes: a support frame, and a driving shaft movably mounted on the support frame, a separating wheel being provided on the driving shaft. The driving shaft is movable freely up and down on the support frame, and an elastic component is provided between the driving shaft and the support frame. The elastic component has one end fixed to the support frame, and another end mounted on the driving shaft, which allows the separating wheel to always keep a downward pressure to cards under the action of an elastic force. The elastic component in contact with the driving shaft provides downward pressure to the driving shaft, thus the separating wheel always keeps downward pressure to the cards under the action of the elastic force.
