Display substrate, display panel and display device

A display panel, comprising a display substrate, wherein the display substrate comprises:

• a base substrate and at least a semiconductor pressure sensor disposed in the base substrate, wherein the semiconductor pressure sensor comprises a first connection terminal, a second connection terminal, a third connection terminal and a fourth connection terminal, wherein the first and second connection terminals are configured to receive a bias voltage signal, the third and fourth connection terminals are configured to output a strain voltage signal, and a first line between the first and the second connection terminals is intersected with a second line between the third and the fourth connection terminals;
• a control electrode disposed at a side of the semiconductor pressure sensor, wherein the control electrode are configured to be insulated with the semiconductor pressure sensor, wherein the vertical projection of the control electrode on the plane of the semiconductor pressure sensor lied is overlapped with the semiconductor pressure sensor, and wherein the control electrode is configured to control the semiconductor pressure sensor to be turned on and off;
• and
• a control signal line connected to the control electrode.
