Abstract
The utility model relates to a splicing display for TV walls, comprising a display tube and optic elements; the utility model is characterized in that a plurality of splicing display tubes are arranged behind the TV wall, one end of a light-guiding bundle composed of optic fibres or an image-transmission bundle is positioned on one pixel displayed on the screen of the splicing display tube, and the other end is positioned on a relevant position corresponding to the splicing of the TV wall. According to the same image processing technique for the TV wall, the former pixels on the large screen lost by the splicing of the display tube are displayed again. The utility model has the advantages of simple structure and easy implementation technique; which can effectlvely eliminates grid shadows aroused by the splicing of the TV wall, and watching effect of the large screen can be improved.
Description
The utility model relates to a kind of TV developing device, particularly large-screen " video wall " picture tube piece shade display unit.
In the large screen television technical field, think at present that image quality is best, cost is minimum with television picture tube be stitched together " video wall ".Because have piece between the picture tube of splicing, there is the frame that can not show on the kinescope screen limit, therefore can not displayed image in video wall piece zone, cause to be covered with the grid shade on the video wall whole image, Yan Zhong influences viewing effect.This is a very big weak point of video wall, does not still have effective solution so far.
The purpose of this utility model is for the video wall piece designs a kind of display unit, thereby eliminates the grid shade on the video wall.
Technical solution of the present utility model is, device is made up of piece picture tube and conduction optical fiber, some piece picture tubes are set in the video wall back, the image processing technique same according to video wall is shown in the piece picture tube with the image area that should show in the piece, light guide bundles that optical fiber is formed or biography resemble before Shu Yiduan is positioned at a certain piece pixel that shows on the piece kinescope screen, one end is arranged in corresponding video wall picture tube piece relevant position, and the image on the piece picture tube is sent to relevant position in the piece.Like this, the pixel of losing because of the picture tube piece originally on the large-screen picture can show again, thereby has eliminated the grid shade of video wall.
The adjacent boundary of per two picture tubes just forms a piece on the video wall.Because video wall picture tube piece quantity is more, the quantity of piece picture tube can be equal to or less than piece quantity, be that the piece picture tube is corresponding one by one with piece or a piece picture tube is simultaneously corresponding with several pieces, concrete quantity is optionally decided with possibility with corresponding mode.The piece picture tube is consistent with video wall picture tube type, can be black and white kinescope, chromoscope or high resolution display tube.Transmitting the used optical fiber of piece image that the piece picture tube shows, can be that light guide bundles or the biography that silica fiber, glass optical fiber or plastic fiber boundling are made resembles bundle.Use the light guide bundles cost lower, every corresponding in principle pixel of light guide bundles, if corresponding several pixels, then the resolution of this part is with influenced.Use biography to resemble bundle and can obtain very high visual resolution, but price is higher.For making piece range image display effect better, optical fiber light-guiding bundle or biography can be resembled the end that bundle is positioned at edge joint position, perpendicular to the piece direction, make pre-large post-small horn shape, the big end margin of its loudspeaker just in time covers in the frame that picture tube panel edge can not participate in luminous demonstration, be convenient to light guide bundles so on the one hand or biography resembles installing and fixing of bundle, the pixel lost of the frame region that video wall kinescope screen limit can not be shown shows on the one hand.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Fig. 1 is a video wall piece origin cause of formation schematic diagram.
Fig. 2 is a video wall piece enlarged diagram.
Fig. 3 is the utility model video wall piece display device structure schematic diagram.
As shown in Figure 1, some picture tube 1 splicings form video wall, have piece zone 2 between the picture tube.
As shown in Figure 2, piece zone between the picture tube 1 comprises that piece 3 and picture tube panel can not participate in the frame 4 of luminescence display all around, be the glass bulb sidewall thickness for black and white kinescope this " frame ", and on chromoscope, this " frame " is exactly to shield the zone that the limit is not coated with fluorescent material.
As shown in Figure 3, in video wall picture tube 1 back piece picture tube 5 is set, the image that should show in the piece zone is presented on the corresponding piece picture tube 5, if the corresponding piece picture tube 5 of several pieces, the visual display respectively that then should show in these several pieces is on the corresponding position of this correspondence piece picture tube 5. Before optical fiber light-guiding bundle (or biography resembles bundle) 6, one ends were positioned at position of image corresponding on piece picture tube 5 fluorescent screens, an end is arranged in the corresponding position of piece 3, and was one by one corresponding, arranges one by one, and a rule piece is filled up. Optical fiber light-guiding bundle (or biography resembles bundle) 6 ends that are positioned at piece are being pre-large post-small horn shape perpendicular to the piece direction, and size cooperates with piece position, place, makes the big end margin 7 of its loudspeaker just in time hide the frame 4 that the kinescope screen limit can not show.
Embodiment is that the video wall that chromoscope is formed is equipped with the piece display unit, and the piece picture tube is a chromoscope, and model is identical with chromoscope on the video wall, places about half meter behind the video wall, four pieces of one correspondence; The light guide bundles that conduction optical fiber adopts SGX-BOX plastic fiber boundling to form, optical fiber filament diameter 0.6～1mm, light guide bundles are positioned at the end flare shape of piece, and area of section is decided according to the requirement of visual resolution, arranges one by one, fills up piece.The utility model apparatus structure is simple, eliminates the grid shade that cause in video wall piece zone effectively, improves the effect of watching of large-screen tv wall.
Claims (3)
1, a kind of piece display unit of splicing the video wall of forming by picture tube, it is characterized in that forming by piece picture tube and conduction optical fiber, some piece picture tubes are set in the video wall back, light guide bundles that optical fiber is formed or biography resemble before Shu Yiduan is positioned at a certain piece pixel that shows on the piece kinescope screen, and an end is arranged in corresponding video wall picture tube piece relevant position.
2, video wall piece display unit according to claim 1 is characterized in that the quantity of piece picture tube is less than or equal to picture tube quantity on the video wall, and its type is consistent with picture tube on the video wall.
3, video wall piece display unit according to claim 1 and 2, it is characterized in that light guide bundles that optical fiber is formed or biography resemble the end that bundle is positioned at edge joint position and making pre-large post-small horn shape perpendicular to the piece direction, the big end margin of its loudspeaker just in time covers in " frame " that edge joint position kinescope screen limit can not luminous demonstration.
