The present invention provides a display module () and an electronic terminal. The display module () comprises: a first display unit () configured to display first image information in a first direction; a second display unit () configured to display second image information in a second direction; and a sensor unit () provided between the first display unit () and the second display unit () and configured to sense an object's approach or touch on the first display unit () and/or the second display unit (). With the display module (), the object's approach or touch on the first display unit () and the second display unit () can be sensed by a single sensor unit (). There is no need to provide a sensor unit () for each of the display units () for touch sensing function. In this way, it is possible to reduce the thickness of the display module (), make it slimmer and more beautiful while reducing manufacture cost.

The present invention provides a control method for switching display between a plurality of OSs as well as a computer system. The method comprises: detecting that the currently displayed guest operating system (GOS) is required to be switched from a first GOS to a second GOS; determining whether the first GOS satisfies a preset switching condition, and switching the currently displayed GOS to the second GOS if the preset switching condition is satisfied, and otherwise, prohibiting the switching from the currently displayed GOS. With the method and the computer system, it is possible to avoid picture distortion or blurring or system collapse in switching display between a plurality of OSs.

Control method and computer system for switching display between OSs

A method for guaranteeing the security of critical data, which is used in a terminal including a secured chip and includes the steps of: activating the secured chip by the terminal platform to receive cryptograph A of said critical data; parsing internally by the secured chip the cryptograph A with a preset key A to generate a plaintext, then encrypting said plaintext with a preset key B to generate cryptograph B, and returning the cryptograph B to the terminal platform. Since cryptograph conversion is performed inside the secured chip, and the process of converting the cryptograph A to the cryptograph B is completed inside the secured chip as a one-shot action, the secured chip cannot be eavesdropped upon or stolen by any vicious software, and thus the critical data is guaranteed to be always in a cryptograph status from the secured input device to the remote server, which ensures the security of the critical data. In addition, the present invention is low in cost, advantageous in spreading and application, and convenient in customization and upgrading. The present invention further provides a terminal and a secured chip.
