Abstract
Provided are a touch display panel and a touch display device. The touch display panel includes at least one semiconductor pressure-sensing touch device, and the semiconductor pressure-sensing touch device includes a first pressure-sensitive resistor, a second pressure-sensitive resistor, a third pressure-sensitive resistor and a fourth pressure-sensitive resistor. A first end of the first pressure-sensitive resistor and a first end of the second pressure-sensitive resistor are connected to a first power inputting terminal, a second end of the first pressure-sensitive resistor and a first end of the fourth pressure-sensitive resistor are connected to a first sense signal measuring terminal, a second end of the fourth pressure-sensitive resistor and a second end of the third pressure-sensitive resistor are connected to a second power inputting terminal.
