DISPLAY SYSTEM WITH A VIRTUAL DISPLAY

摘要

A system for generating a virtual display that is displayed on an existing monitor using a memory (e.g., graphics processing unit (GPU) memory, random access memory (RAM), etc.) of a connected device (e.g., a computer) as a frame buffer for the virtual display. For example, the virtual display may use the RAM or the memory of the GPU of the connected device as a second frame buffer to generate the frames displayed in the virtual display. The virtual display is not a physical display and, thus, does not require any additional hardware or physical space. Rather, the virtual display is displayed on a pre-existing display. The pre-existing display is also used to display the frames generated in a first frame buffer.

1. A display system for generating a virtual display, the display system comprising:
a display; and a display controller including a first frame buffer configured to provide first frames to the display and a second frame buffer configured to provide second frames to the display; wherein content of the first frames and content of the second frames is transferred to the display and simultaneously displayed by the display such that the content of the second frames at least partially overlap and obscure the content of the first frames.
