Embodiment
The utility model provides a kind of vehicle carried video to divide screen display system.Said vehicle carried video divides screen display system to comprise vehicle-carrying display screen, FPGA development board, navigating instrument, multimedia player; Said navigating instrument links to each other with the FPGA development board through video input connecting line with multimedia player; Said FPGA development board is connected to vehicle-carrying display screen; Said vehicle-carrying display screen is provided with original screen panel, and said original screen panel comprises by angle distinguishes the grating that shows multimedia video signal and navigating instrument signal.
Further describe below in conjunction with specific embodiment.
See also Fig. 1, divide the general structure synoptic diagram of screen display system for the utility model vehicle carried video.
Said vehicle carried video divides screen display system to comprise vehicle-carrying display screen, FPGA development board, navigating instrument, multimedia player.
At first definable vision signal one is the navigating instrument vision signal; Vision signal two is a multimedia player, like DVD vision signal, MP5 vision signal etc., can choose any one kind of them.
Said navigating instrument links to each other with the FPGA development board through video input connecting line with multimedia player; Vision signal one and vision signal two are inputed to the FPGA development board, and the liquid crystal driver module that is integrated on the FPGA development board becomes digital signal with the vision signal of importing from analog signal conversion.
Said FPGA development board is connected to vehicle-carrying display screen through video output soft arranging wire.Said FPGA development board carries out digital decoding respectively again with vision signal one and vision signal two, and according to the original screen panel structural principle on the following vehicle-carrying display screen, digital signal is outputed to vehicle-carrying display screen.
Said vehicle-carrying display screen is provided with an original screen panel.The structural principle of said original screen panel is please with reference to Fig. 2.
The structure of said original screen panel is following: 1,3,5,7 ... Be the grating of display video signal one, 2,4,6,8 ... Grating for display video signal two.
When making said original screen panel, following scheme is arranged:
Consult Fig. 2; Get a substrate, with laser substrate is left the slanted bar groove, the scope of fluting is at the center section of substrate; Do not slot in the two ends up and down of substrate; The grating that such rule has the slanted bar groove just can not rupture, because reserved plate body and connect in two up and down at grating, and the slanted bar angle of the v-groove of odd and even number is different.
Consult Fig. 2, get a substrate, earlier two ends above the substrate are clamped, substrate is left the slanted bar groove by strange, dual pixel, end the back, after cooling, can need cut whole transparent panel by size to inserting filling material in its slanted bar groove with laser.
Consult Fig. 3, get a substrate, earlier two ends above the substrate are clamped; Intersect out the slanted bar groove at strange or dual pixel with laser again, after strange or dual pixel have been opened the slanted bar groove, filling material is inserted in the slanted bar groove; After cooling, more occasionally strange pixel is opened the slanted bar groove, at last occasionally strange pixel is also inserted filling material; Institute's slanted bar angle of the v-groove of opening gradient on the odd and even number pixel can be accomplished difference, and size is cut whole substrate on demand at last.
Said filling material can be resin, also can be materials such as acrylic.
After original screen panel is installed on the existing Vehicular display device, through on the FPGA development board, programming, when being input to vision signal one on the vehicle-carrying display screen according to 1; 3,5,7 ... The pixel of this odd number shows; And vision signal two when being input on the vehicle-carrying display screen by 2,4,6; 8 ... The pixel of this even number shows, because the angle of the grating of odd and even number is different, therefore; Just can the content regions of the content of video one and video two be assigned to the both sides of pilothouse and copilot chamber by angle through grating mould or original screen panel, the driver of pilothouse sees the content of navigating instrument, and the passenger of copilot sees multimedia content; Can not obscure each other, and can show navigator appearance all over the screen and multimedia content.
Not; The FPGA development board can also be carried video signal source to other Vehicular videos; As be placed in the display screen that original screen panel is not installed at pilothouse and seat, copilot chamber; Or only be installed in the display screen that original screen panel be housed of the middle locker of pilothouse and copilot chamber rear in the face of back seat, can and on display screen, be nested with original screen panel through programming in the FPGA development board and reach required display requirement and effect.
In addition; Optical grating construction on the original screen panel is not limited to by the slanted bar angle of the v-groove difference of odd and even number and distinguishes different video; The slanted bar angle of the v-groove that also can be the left side and the right is different; Or different or the like the modes of the slanted bar angle of the v-groove of bottom and upper segment distinguish different video contents, repeat no more here.
In sum; The vehicle carried video that the utility model embodiment is provided divides screen display system, through on vehicle-carrying display screen, increasing original screen panel, different video signals is distinguished demonstration with different angles; Convenient different people watches different contents, has increased the recreational and security of journey.
More than vehicle carried video that the utility model embodiment is provided divide screen display system to carry out detailed introduction; Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the technical scheme that the utility model discloses; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
