Display system with a virtual display

A system is provided for generating a virtual display (21) that is displayed on an existing display (2) using a memory of a device as a frame buffer for the virtual display. The virtual display may use random access memory (RAM) or memory of the graphics processing unit (GPU) of the device (e.g. a computer) as a second frame buffer (17) 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 the existing display. The existing display is also used to display the frames generated in a first frame buffer (16). 提供了用于产生显示在现有显示器(2)上的虚拟显示器(21)的系统，该虚拟显示器使用设备的存储器作为用于虚拟显示器的帧缓冲器。该虚拟显示器可以使用设备(例如计算机)的随机存取存储器(RAM)或图形处理单元(GPU)的存储器作为产生显示在虚拟显示器中的帧的第二帧缓冲器(17)。该虚拟显示器不是物理显示器，因此不需要任何附加的硬件或物理空间。而是在现有显示器上显示该虚拟显示器。现有显示器也可以用于显示在第帧缓冲器(16)中产生的帧。
