Embodiments of the present invention disclose an unlocking method, a device for touch screen terminal and a touch screen terminal. The method includes: performing a touch unlocking operation to an unlocking unit, wherein the unlocking unit is at least one active area corresponding to the unlocking operation and provided on the touch screen with an area smaller than that of the entire screen; and when the touch screen terminal is in a non-service state, the active area is in a service state or a standing by state; when detecting the touch unlocking operation, generating an unlocking request signal; and providing an unlocking operation interface according to the unlocking request signal. Therefore, the unlocking operation does not depend on a physical key any more, which allows a light and thin profile and a simple and clear appearance, and reduces damage ratio of terminal's components, and at the same time the non-entire screen unlocking operation interface is advantageous for low power consumption requirement on the touch screen.
