A first switching unit, a second switching unit and a fifth switching unit of a first sub pixel circuit and a first switching unit, a second switching unit and a fifth switching unit of a second sub pixel circuit share a scanning signal line. In the pixel circuit, the operating current flowing through the electroluminescent unit is not affected by the threshold voltage of the corresponding driving transistor, which solves the problem of non-uniformity of display luminance because of the threshold voltage drift of the driving transistor. At the same time, driving of two pixels is completed by using one compensation circuit, and the two adjacent pixels share a plurality of signal lines, which can reduce a number of signal lines used for the pixel circuit in the display apparatus, reduce a cost of an integrated circuit, decrease pixel spacing and achieve a higher pixel density."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pixel circuit and display apparatus","description":"A pixel circuit comprising two sub pixel circuits, each of which includes: five switching units, a driving unit, an energy storage unit and an electroluminescent unit.
