Abstract

Embodiments of the invention provide a screen projection display method and a mobile terminal. The method comprises the steps of rotating an image frame to be subjected to screen projection for a preset angle; according to a relationship between a first resolution of a screen of a screen projection device and a second resolution of the rotated image frame, performing zooming on the rotated image frame to generate a target image frame; and projecting the target image frame to the screen projection device for performing display. The image frame to be subjected to the screen projection is rotatedto be changed to be in a horizontal screen state from a vertical screen state, so that the image frame can be displayed in the screen of the screen projection device to the maximum extent; and further, the rotated image frame is zoomed to completely display the image frame to be subjected to the screen projection in the screen of the screen projection device and avoid a distortion phenomenon, sothat the usage experience of a user is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a projection screen display method and a mobile terminal. Background technique [0002] At present, the mobile terminal can deliver the information on the screen of the mobile terminal to the screen of the screen projection device through the wireless video display technology. For example, watching a movie on a mobile terminal with a screen that is too small is not enough experience, and the movie is cast to a screen-casting device to watch, etc. [0003] Because the screen of the mobile terminal is inconsistent with the normal display direction of the screen of the projection device, the screen of the mobile terminal is displayed vertically by default, while the screen of the projection device is displayed in landscape. The image frame on the terminal can only be partially projected in the middle of the screen of the projection device, the left and right sides ...
