Abstract
Provided are a pixel circuit, a driving method thereof and a display apparatus. The pixel circuit includes a first switching module (10), a first driving module (20), a second switching module (30), a second driving module (40), a coupling module (50) and a light-emitting module (60). The first switching module (10) is connected with a first scan signal terminal (Vscan1), a data signal terminal (Vdata), the first driving module (20) and the coupling module (50) respectively; the second switching module (30) is connected with a second scan signal terminal (Vscan2), the data signal terminal (Vdata), the second driving module (40) and the coupling module (50) respectively; the coupling module (50) is further connected with a first voltage terminal (Vdd), the first driving module (20) and the second driving module (40); the first driving module (20) is further connected with the first voltage terminal (Vdd) and the light-emitting module (60); the second driving module (40) is further connected with the first voltage terminal (Vdd) and the light-emitting module (60); the light-emitting module (60) is further connected with a enable signal terminal (Em) and a second voltage terminal (Vss…
