Abstract
The embodiment of the disclosure discloses a touch substrate, a touch display panel and a method for calculating touch pressure. The touch substrate comprises at least two semiconductor pressure sensors, a bias voltage applying circuit and a voltage detecting circuit, wherein the bias voltage applying circuit is used for applying bias voltage to each semiconductor pressure sensor; the voltage detecting circuit is used for acquiring strain voltages of each semiconductor pressure sensor. A first straight line connecting the first connecting terminal and the second connecting terminal intersects a second straight line connecting the third connecting terminal and the fourth connecting terminal. According to the technical scheme of the disclosure, the semiconductor pressure sensors can be integrated inside the touch display panel.
