Abstract: A method and a system for rotating a display image applied to an electronic display device which includes a display image are provided. The method includes at least the following steps: enabling a rotation mode; capturing user information relative to the electronic display device via an image capturing unit; receiving the user information via an analysis unit and generating analysis information according to the user information; and receiving the analysis information via a processing unit and generating a control signal to control the display image to rotate according to the analysis information.

Abstract: A method for controlling an eye tracking applied to an electronic display device which includes a display screen and executes at least one application program is provided. The method includes at least the following steps: enabling an eye tracking control mode; capturing an eye image via an eye tracking detection unit and generating eye position information; receiving the eye position information via an analysis unit and mapping the eye position information to the display screen to generate analysis information; receiving the analysis information via a processing unit and generating an eye tracking cursor according to the analysis information, wherein the processing unit generates a preview window on the display screen according to a position of the application program corresponding to the eye tracking cursor.

Abstract: A display module of an electronic device is for showing an operation interface of a first screen on a second screen of the electronic device, and the first screen is disposed on an opposite side of the second screen. The display module includes a graphics processing unit and a screen control unit. The graphics processing unit is coupled to a processing unit of the electronic device, the graphics processing unit receives display information from the processing unit, and the display information has a first pixel data, and the graphics processing unit processes the first pixel data to generate second pixel data. The screen control unit outputs the first pixel data to the second screen and a second display frame is displayed, and the screen control unit receives the second pixel data and outputs the second pixel data to the operation interface.
