Embodiment
In the lump with reference to figure 3, the black surround that video wall 100 also comprises two mosaic display screens 10 and is arranged at two display screen 10 seam crossings is eliminated structure 20, and wherein each display screen 10 comprises and shows main body 11 and be arranged at the frame 12 that shows main body 11 sides.
This black surround is eliminated structure 20 and is comprised a triangular prism 21 and two quadrangulars 22.A wherein side of this triangular prism 21 fits on the frame 12 of above-mentioned two adjacent display screens 10, and other two sides are provided with reflecting surface 210, for the light reflection that quadrangular 22 is launched.These two quadrangulars 22 are covered on display screen and show in main body 11 near the part of frame 12.Respectively have a side and above-mentioned two reflectings surface 210 of triangular prism 21 of two quadrangulars 22 fit.In the middle of other embodiments, above-mentioned reflecting surface 210 can be arranged on quadrangular 22 equally.This quadrangular 22 is made and be coated with semi-transparent semi-reflecting film 220 on the side of triangular prism 21 for transparent material, for by the light part reflection of injecting and part refraction.
The light part that display screen 10 penetrates can penetrate above-mentioned semi-transparent semi-reflecting film 220, part reflects the above-mentioned reflecting surface 210 to triangular prism 21, above-mentioned light is reflected quadrangular 22 by this reflecting surface 210, make the position of frame 12 in observer's eye also have the light that produces image to penetrate, and then reach the effect of eliminating black surround.In the middle of present embodiment, the angle α that described quadrangular 22 arranges between side and the above-mentioned display screen 10 of semi-transparent semi-reflecting film 220 is roughly 45 °.So make, the image anaclasis that approaches half goes out semi-transparent semi-reflecting film 220, and second half image light reflexes to the reflecting surface 210 of triangular prism 21 and reflected quadrangular 22 completely, make this black surround eliminate structure 20 to affect light even.
In the middle of present embodiment, described video wall 100 also comprises the cover plate 30 being arranged in demonstration main body 11 other parts, and this cover plate 30 is made up of transparent material and end face maintains an equal level mutually with the end face back to display screen 10 of above-mentioned quadrangular 22.
