PIXEL CIRCUIT AND DRIVE METHOD THEREFOR, AND DISPLAY DEVICE |
摘要 |
A pixel circuit, a drive method for a pixel circuit and a display device. A second transistor (T2) is connected between a control electrode of a drive transistor (T1) and an ON electrode to form a diode-connected topological structure. By virtue of the circuit structure and the cooperation with a storage capacitor (Cs), during current row gating, a threshold voltage (VTH_T1) of the drive transistor (T1) and grey scale-related data voltage information (VDATA) are extracted and stored on the storage capacitor (Cs), thereby compensating the threshold voltage (VTH_T1) of the drive transistor (T1) and increasing the contrast of a display. |
