Title: PIXEL CIRCUIT AND DRIVE METHOD THEREOF, AND DISPLAY DEVICE
Abstract:
A pixel circuit and drive method thereof, and display device; the pixel circuit comprises a first transistor (T1), a second transistor (T2), a third transistor (T3), a fourth transistor (T4), a fifth transistor (T5), a first storage capacitor (C1), a second storage capacitor (C2), and a light emitting device (L). The pixel circuit reduces the display brightness nonuniformity of a display device and extends the service life thereof by compensating for the threshold voltage drift of the first transistor (T1).
