US 2012/0236012 A1 · Method and Device for Displaying Application Image

Abstract

A method and a device for displaying an application image are provided, and the method includes the following steps: receiving a display request from a second operating system, and reading the application image stored in a storage area; judging whether it is required to process the application image through a window manager according to the configuration of the local image display system, and if required, sending the application image to the window manager, and sending the application image processed by the window manager to a display graphics library for processing; if not, directly sending the application image to the display graphics library for processing; and acquiring the location of the display memory through a display driver, sending the application image processed by the display graphics library to the display memory, and displaying the application image through the display memory. Using the solution, the application image of the installable operating system can be displayed in the local operating system.
