Claim 9:
10. A mobile terminal-based virtual reality display system, the system comprising a mobile terminal and a virtual reality head-mounted device;
the mobile terminal is connected onto the virtual reality head-mounted device in a removable manner and it comprises one processing unit, a main screen and a virtual reality screen; relative to the main screen, the virtual reality screen is close to an user operation side of the virtual reality head-mounted device; both the main screen and the virtual reality screen have communication links with the processing unit; the processing unit is configured to control the main screen unit to export video signals to the virtual reality screen so that the virtual reality screen can play the video signals; the main screen is the screen for routine use, the virtual reality screen is normally not on and will be turned on only when VR experience is underway;
the mobile terminal further comprises a video signal interface for communication with the virtual reality head-mounted device; the video signal interface has communication links with the main screen; the processing unit is configured to export the video signals to the virtual reality head-mounted device via the video signal interface so that the virtual reality head-mounted device can play the video signals;
the mobile terminal further comprises a video processing unit;
the processing unit, virtual reality screen and video signal interface all have communication links with the video processing unit;
the video processing unit is configured to compress the video signals to create compressed video data and transmit the compressed video data to the virtual reality screen and the virtual reality sub-screen of the virtual reality head-mounted device so that the virtual reality screen and the virtual reality sub-screen of the virtual reality head-mounted device can analyze the compressed video data and acquire video signals;
the virtual reality head-mounted device comprises a virtual reality sub-screen; the virtual reality sub-screen has communication links with the video signal interface; the virtual reality sub-screen is configured to play the video signals;
the virtual reality sub-screen of the virtual reality head-mounted device and the virtual reality screen of the mobile terminal constitute a twin-screen display mode together; the virtual reality head-mounted device connects the virtual reality sub-screen into the mobile terminal via HDMI or DP interface to constitute the twin-screen display mode; the virtual reality screen of the mobile terminal has a higher resolution and thus can realize the virtual reality support of mobile terminal, wherein resolution of the virtual reality screen of the mobile terminal is higher than resolution of the main screen of the mobile terminal.
