<p>A voltage driving pixel circuit, a driving method therefor, and a display panel comprising the voltage driving pixel circuit. The voltage driving pixel circuit comprises: a driving transistor (1), a hold transistor (2), a switch transistor (3), a compensation transistor (4), a storage capacitor (5), and an OLED component (6). A gate electrode of the switch transistor (3) is connected to a gate line (SCAN), a source electrode of the switch transistor (3) is connected to a data line (VD), and a drain electrode of the switch transistor (3) is connected to one end of the storage capacitor (5) and to a source electrode of the hold transistor (2). A gate electrode of the hold transistor (2) is connected to a first control signal cable (EM), the first control signal cable (EM) controls the connection and disconnection of the hold transistor (2), and a drain electrode of the hold transistor (2) is connected to a gate electrode of the driving transistor (1). A gate electrode of the compensation transistor (4) is connected to a second control signal cable (VC), and the second control signal cable (VC) controls the connection and disconnection of the compensation transistor (4). A source electrode of the compensation transistor (4) is connected to a drain electrode of the driving transistor (1), and a drain electrode of the compensation transistor (4) is connected to a gate electrode of the driving transistor (1). A source electrode of the driving transistor (1) is connected to the other end of the storage capacitor (5) and to a positive electrode of the OLED component (6). The drain electrode of the driving transistor (1) and the source electrode of the compensation transistor (4) are both connected to a first power supply cable (VP), and a negative electrode of the OLED component (6) is connected to a second power supply cable (VN). The driving circuit effectively compensates the threshold voltage non-uniformity of the n-type TFT driving transistor (1) and the non-uniformity of the OLED component (6).</p> |
