A pixel circuit, comprising:

• a luminous device, a photosensitive device, a drive control sub-module, a data write sub-module, a light-emitting control sub-module and a touch detection sub-module;
• wherein,
• a first terminal of the drive control sub-module is connected to a first terminal of the data write sub-module and a first terminal of the photosensitive device, respectively, a second terminal of the drive control sub-module is connected to a first terminal of the luminous device and a second terminal of the data write sub-module, respectively, a third terminal of the drive control sub-module is connected to a first terminal of the light-emitting control sub-module and a first terminal of the touch detection sub-module, respectively;
• a third terminal of the data write sub-module is connected to a data signal terminal, a fourth terminal of the data write sub-module is connected to a scan signal terminal, a fifth terminal of the data write sub-module is connected to a first reference signal terminal, a second terminal of the luminous device and a second terminal of the light-emitting control sub-module, respectively, a sixth terminal of the data write sub-module is connected to a third terminal of the light-emitting control sub-module;
• under the control of the scan signal terminal, a data signal at the data signal terminal is transmitted to the drive control sub-module by the data write sub-module;
• a fourth terminal of the light-emitting control sub-module is connected to a second reference signal terminal and a second terminal of the touch detection sub-module, respectively, a fifth terminal of the light-emitting control sub-module is connected to a light-emitting control signal terminal;
• under the control of the light-emitting control signal terminal, the light-emitting control sub-module controls the drive control sub-module to drive the luminous device to give off light;
• a third terminal of the touch detection sub-module is connected to a second terminal of the photosensitive device, a fourth terminal of the touch detection sub-module is connected to a touch signal read terminal, a fifth terminal of the touch detection sub-module is connected to a touch control signal terminal;
• under the control of the touch control signal terminal, the touch detection sub-module controls output of a touch detection signal from the drive control sub-module to the touch signal read terminal, the touch detection signal being decreased as the light intensity irradiated onto the photosensitive device is increased.
