Abstract
Provided are a pixel structure and driving method thereof, and a display apparatus. The pixel structure comprises a plurality of pixel units and compensation units corresponding to the pixel units. Each of the pixel units comprises two adjacent pixel circuits which are a first pixel circuit and a second pixel circuit. The first pixel circuit comprises a first driving transistor (DTFT1) and a first display device (OLED1), and the second pixel circuit comprises a second driving transistor (DTFT2) and a second display device (OLED2), wherein the first pixel circuit and the second pixel circuit share the compensation unit and are controlled by a same data line (Data). The compensation unit is configured to adjust a gate voltage of the first driving transistor (DTFT1) in the first pixel circuit to eliminate the influence of the threshold voltage of the first driving transistor (DTFT1) on the driving current of the first display device (OLED1), and to adjust a gate voltage of the second driving transistor (DTFT2) in the second pixel circuit to eliminate the influence of the threshold voltage of the second driving transistor (DTFT2) on the driving current of the second display device (OLE…
