Pixel circuit, method for driving the same, and display apparatus
Aspects of the present disclosure provide a pixel circuit, a method for driving the same, and a display apparatus. The pixel circuit comprises a display driving circuit. The display driving circuit comprises a reset sub-circuit, a writing sub-circuit, a driving sub-circuit, a light-emitting control sub-circuit, and a light-emitting device. The reset sub-circuit is configured to reset the driving sub-circuit. The writing sub-circuit is configured to write a data voltage into the driving sub-circuit. The light-emitting control sub-circuit is connected to the driving sub-circuit and an anode of the light-emitting device and is configured to provide driving current, through the driving sub-circuit, for causing the light-emitting device to emit light. The pixel circuit further comprises a detection circuit configured to collect incident light and output a collection result to the read signal line. One or more transistors are shared between the detection circuit and the display driving circuit.
