Abstract
A method and system for unlocking a mobile phone screen includes, in a locked state, the mobile phone receives a user instruction, lights up a mobile phone screen, and enters an unlocking interface. In a case that a touching event has been detected within a per-determined time period, touching region information, corresponding to the touching event, is obtained and a touching area is calculated based on the touching region information. The touching area is compared with a per-determined threshold and, when the touching area is larger than the pre-determined threshold, the touching event is determined to meet a requirement for unlocking, and the mobile phone is controlled to unlock the mobile phone screen. Otherwise, unlocking failure information is returned to the user. Thereby, mobile phone screen unlocking is achieved by way of a large area touching of a mobile phone screen.
