Abstract:
The present disclosure relates to pressure-sensitive detection apparatus. One example apparatus includes a pressure sensor array located in a touch display screen. One half-bridge circuit is constituted in each row of the pressure sensor array. When there is a touch input signal on the touch display screen, a first half-bridge circuit and a second half-bridge circuit corresponding to a touch location of the touch input signal output signals. A deformation amount generated when pressure is applied to a first pressure sensor component in the first half-bridge circuit is less than a deformation amount generated when the pressure is applied to a second pressure sensor component in the first half-bridge circuit, and a deformation amount generated when the pressure is applied to a first pressure sensor component in the second half-bridge circuit is greater than a deformation amount generated when the pressure is applied to a second pressure sensor component in the second half-bridge circuit.
