发明名称 PIXEL CIRCUIT AND DRIVE METHOD THEREFOR, ORGANIC LIGHT-EMITTING DISPLAY PANEL AND DISPLAY DEVICE
摘要 <p>A pixel circuit and a drive method therefor, an organic light-emitting display panel and a display device. A drive transistor (DTFT), a first capacitor (CST), an organic light-emitting diode (OLED), a first control unit (11) and a drive unit (12) are arranged in the pixel circuit. In the pixel circuit, by way of directly inputting a data voltage (Vdata) to the gate electrode of the drive transistor (DTFT), the potential of the gate electrode of the drive transistor (DTFT) is fixed. Meanwhile, a threshold voltage (Vthd) of the drive transistor (DTFT) is saved in the storage capacitor (CST) by using the self-discharge of the storage capacitor (CST), and a constant potential (Vref) is introduced in one electrode of the storage capacitor (CST) so as to eliminate the influence of the internal resistance of the circuit on a light-emitting current, thereby reducing the non-uniformity of the panel image display.</p>
