Title: PIXEL CIRCUIT AND DRIVING METHOD THEREFOR, ORGANIC LIGHT-EMITTING DISPLAY PANEL, AND DISPLAY DEVICE
Abstract:
A pixel circuit and a driving method therefor, an organic light-emitting display panel, and a display device. The pixel circuit has arranged therein a touch induction module (13), a driver transistor (T6), a driver control module (11), and a light-emitting module (12). The pixel circuit utilizes a diode connection scheme of the driver transistor (T6) and discharging of a storage capacitor (C1) to compensate a threshold voltage of the driver transistor (T6), thus making a driving current of the driver transistor (T6) to be unrelated to the threshold voltage of the driver transistor (T6), thereby allowing for consistent OLED-driving currents at different locations in the organic light-emitting panel, and allowing for improved uniformity of brightness and reliability of the organic light-emitting panel.
