PIXEL CIRCUIT, DRIVE METHOD THEREOF, DISPLAY PANEL, AND DISPLAY APPARATUS

摘要

A pixel circuit, drive method thereof, display panel, and display apparatus. In the pixel circuit, a drive transistor (T0) has one of its source and drain connected to a control voltage line (VDD), and the other connected to a light emitting device (EL); a storage capacitor (Cs) has a first end connected to a gate of the drive transistor (T0), and a second end connected to the control voltage line (VDD); a conducting unit (11) has a first end connected to a scan line (Gn), a second end connected to a data line (Dn), a third end connected to a first end of an addressing unit (12), and a fourth end connected to a common end (GND), and the conducting unit (11) is configured to conduct between the second end and the third end if the first end is at a first voltage level and to conduct between the third end and the fourth end if the first end is at a second voltage level; the addressing unit (12) has a second end connected to the data line (Dn), and a third end connected to the first end of the storage capacitor (Cs), and the addressing unit (12) is configured to conduct between the second end and the third end if the first end is at an active voltage level. The present invention addresses the amplitude loss problem occurred during transmission of a scanning signal if an input impedance at an input location of the scanning signal is not large enough.
