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.

Abstract: A locking method and a related device are provided. The method is applied to an electronic device, where the electronic device includes a processor and a locking control circuit, and the locking control circuit is capable of running when the electronic device is in a power-off state or a power-on state. The method includes: modifying, by the locking control circuit, a state flag to a first state flag when the electronic device needs to be locked, where the first state flag is used to indicate a state that the electronic device needs to be locked and is not locked; controlling, by the locking control circuit, the electronic device to restart; reading, by the processor, the state flag in a startup phase of the electronic device restart; and locking the electronic device when the processor determines that the state flag is the first state flag.
