Optionally, the pixel compensation sub-unit circuit further includes a compensation control sub-circuit. The compensation control sub-circuit is connected to the reading line and is connected to a data driving sub-circuit connected to the data line. The compensation control sub-circuit is configured to read an electrical signal in the reading line, compare a value of the electrical signal with a pre-determined electrical signal value, determine whether a voltage in the data line needs to be adjusted or not according to a result of the comparison; and in case that the voltage in the data line needs to be adjusted, the compensation control sub-circuit is configured to send a data voltage adjustment signal to the data driving sub-circuit so that the data driving sub-circuit obtains the data voltage adjustment signal. The data driving sub-circuit is configured to adjust a data voltage to be outputted to the data line according the data voltage adjustment signal and obtain an adjusted data voltage, and send the adjusted data voltage to the at least one sub-pixel sub-circuit through the data line.
Optionally, the second voltage input terminal and the third voltage input terminal are a same voltage input terminal. Both the second voltage input terminal and the third voltage input terminal are low voltage input terminals. The photosensitive sub-circuit includes a photosensitive diode, an anode of the photosensitive diode is connected to the third voltage input terminal, and a cathode of the photosensitive diode is connected to the reading control sub-circuit.
