A pixel circuit and display device; the pixel circuit comprises three sub-pixel circuits (P1, P2, P3) and one power supply circuit (VL), the three sub-pixel circuits (P1, P2, P3) sharing a data line (Data); the power supply circuit (VL) is connected to a first level end (VA), a first signal control line (EM1) and the sub-pixel circuits (P1, P2, P3), to provide a first level for the sub-pixel circuits (P1, P2, P3) via the first level end (VA) according to a signal control of the first signal control line (EM1); the sub-pixel circuits (P1, P2, P3) are connected to the power supply circuit (VL) and the data line (Data), to display a grayscale value according to the first level provided by the power supply circuit (VL) and the data signal control of the data line (Data). The pixel circuit can reduce the number of signal lines used for the pixel circuit, lower the cost of an integrated circuit, and increase the pixel density of a display device. |
