Screen unlocking method and device based on pressure induction touch control technology and terminal

The invention provides a screen unlocking method and device based on a pressure induction touch control technology and a terminal. The screen unlocking method comprises the steps that after an unlocking request triggered by a user is received, a password input mode is displayed on a touch screen; detection is conducted on input of the user, when it is detected that the user presses the touch screen on the basis of the password input mode, a pressure rating prompt corresponding to current pressing intensity is displayed on the touch screen, and unlocking is executed on the condition that the password for pressing executed by the user is the same as a preset password, and each pressing meets preset pressing touch screen intensity and a corresponding relation of the pressure rating and the pressure rating prompt. According to the screen unlocking method and device based on the pressure induction touch control technology and the terminal, in the unlocking process, a reference can be provided for inputting of the user by displaying the corresponding pressure rating prompt in the pressing process, and mistaken input can be avoided; by combining the pressure induction touch control technology, the difficulty of the password is effectively increased, and the safety of the terminal is improved.
