Title: PIXEL CIRCUIT AND DRIVING METHOD, ARRAY SUBSTRATE, DISPLAY PANEL, AND DISPLAY DEVICE
Abstract:
A pixel circuit and driving method, an array substrate, a display panel, and a display device are provided. The pixel circuit includes a voltage clamping unit(11), an energy storage unit(12), and a reference voltage terminal. The voltage clamping unit(11) connects to the reference voltage terminal and a first terminal of the energy storage unit(12). The voltage clamping unit(11) forms a voltage divider circuit to supply a divided reference voltage from the reference voltage terminal to the first terminal of the energy storage unit(12) or pulls and clamps the voltage at the first terminal of the energy storage unit(12) to a reference voltage at the reference voltage terminal.
