The invention discloses a pixel circuit, a display panel and display equipment, and the pixel circuit comprises a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a sixth transistor and a seventh transistor, a light emitting unit; the control electrode of the second transistor is used for inputting a first driving signal; a third transistor; a first electrode of the fourth transistor is connected with the data line, a second electrode is connected with the anode of the light-emitting unit, and a control electrode is used for inputting a seconddriving signal; capacitor. The pixel circuit does not need to be specially provided with an induction line; voltage compensation can be completed by using a data line; the method is suitable for highPPI display; and the fourth transistor only needs to be turned on once for voltage compensation when the row where the fourth transistor is located is selected in the induction period, row-by-row shift design does not need to be carried out on a driving signal of the fourth transistor, and the layout space occupied by the pixel circuit is greatly reduced, so that the narrow bezel of a product canbe realized, and the cost can be reduced.
