Abstract:
The embodiments of the present disclosure disclose a pixel circuit and a method for driving the same, a display panel and a display apparatus. The pixel circuit includes: a driving sub-circuit configured to provide current for causing a light-emitting element to emit light to the light-emitting element under control of a light-emitting control signal; a reset sub-circuit having a reset signal terminal for receiving a reset signal, wherein the reset sub-circuit is connected to the driving sub-circuit and a first terminal of the light-emitting element, and is configured to reset the driving sub-circuit and the first terminal of the light-emitting element under control of the reset signal; a data writing sub-circuit connected to the driving sub-circuit and the reset sub-circuit, and configured to write a data voltage into the driving sub-circuit under control of a first control signal; and a sensing sub-circuit configured to receive a data signal via a first signal terminal, and transmit the data signal to the data writing sub-circuit under control of a second control signal; and sense an external input, and read the sensed external input into a read signal line under control of a read control signal.
