A pixel circuit comprising two subpixel circuits (P1 and P2). Each subpixel circuit comprises: five switch units (T1, T2, T3, T4, and T5), a driver unit (DT), an accumulator unit (C), and an electroluminescent unit (L). The first switch unit (T1), the second switch unit (T2), and the fifth switch unit (T5) of the first subpixel circuit (P1) share a scan signal line with the first switch unit (T1'), the second switch unit (T2'), and the fifth switch unit (T5') of the second subpixel circuit (P2). In the pixel circuit, a working current flowing through the electroluminescent unit is not affected by a threshold voltage of a corresponding drive transistor, thus solving the problem of uneven display brightness caused by shifts in the threshold voltage of the drive transistor. At the same time, one compensation circuit is used to complete driving of two pixels, and adjacent two pixels share multiple signal lines, thus reducing the number of signal lines used in pixel circuits in a display device, reducing integrated circuit costs, reducing pixel pitch, and increasing pixel density. |
