computer program stored in the memory, so as to cause the display device to execute the following operations: when a
mode switching application detects that a first screen mirroring device is connected, controlling the
mode switching application to create a first window, and displaying, in the first window, screen mirroring data sent by the first screen mirroring device, wherein the mode switching application is started after the display device is powered on; and in response to a mode switching operation, controlling the mode switching application to perform switching to a target mode indicated by a mode switching instruction, and according to first
layout data matching the target mode, displaying content to be presented, wherein said content comprises the screen mirroring data sent by the first screen projection device, the first
layout data is used for indicating display parameters of each piece of said content, and at least comprises a
