Description
Technical field
The present invention relates to display technique field, especially a kind of spliced display device.
Background technology
Existing Mosaic screen is all adopt multiple independently display screen to carry out physics to be spliced.Each display screen all adopts frame individual packages.When multiple display screen is spliced to form a giant-screen, there is the rim area occupying one fixed width between adjacent display screen, have a strong impact on the overall display effect of display frame.
Summary of the invention
Given this, be necessary to provide a kind of spliced display device that can improve the overall display effect of display frame.
A kind of spliced display device, comprises the screen be spliced by multiple display screen.The formation rim area, stitching portion of described adjacent display screen.Described spliced display device also comprises transparent light guide body.Described light conductor is covered in the part of screen of described rim area and both sides, rim area.Described light conductor comprises the bottom surface relative with described rim area and the end face opposing with described bottom surface.Described end face is provided with multiple projection.The light that the part of screen of both sides, described rim area sends enters described light conductor by described bottom surface, and after the projection refraction on described end face rim area described in directive.
In above-mentioned spliced display device, the light conductor be covered on rim area can make screen refraction occurs and directive rim area near the light at rim area place, therefore, user is when watching, rim area between adjacent display screen is visually reduced and even eliminates, and improves the overall display effect of picture shown by screen.

Main element symbol description
Following embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1, the spliced display device 100 of first embodiment of the invention comprises multiple display screen 10 and light conductor 50.Combined by physics splicing between multiple display screen 10, to form a larger screen 30.Light conductor 50 is arranged at the junction of adjacent display screen 10.
Display screen 10 comprises display part 11 and the frame 12 for encapsulating display part 11.Display part 11 is watched for user for display frame.Due to frame 12, screen 30 is positioned at the formation rim area, junction 31 of adjacent display part 11.Display screen 10 can be LCDs, plasma panel, CRT display screen or rear projection screen displays.
Refer to Fig. 2 and Fig. 3, light conductor 50 is covered on the part of screen 30 of rim area 31 and both sides, rim area 31.Light conductor 50 is made up of polymethylmethacrylate (polymethylmethacrylate, PMMA) transparent material.Light conductor 50 is xsect cylinder arcuately, and it comprises the end face 52 of the arc between rectangular bottom surface 51 and long a pair limit being connected to bottom surface 51.Bottom surface 51 be covered on rim area 31 and both sides, rim area 31 part of screen 30 on.Bottom surface 51 part corresponding with the part of screen 30 of both sides, rim area 31 forms two incidence surfaces 511.Two incidence surfaces 511 are symmetrical arranged rim area 31 relatively.The width of bottom surface 51 sets according to the width of rim area 31.In the present embodiment, the ratio of the width of bottom surface 51 and the width of rim area 31 is 3:2.End face 52 is provided with multiple protruding 521.Protruding 521 for xsect be the tri-prismoid of isosceles triangle.The length of protruding 521 is equal with the length of light conductor 50.Multiple protruding 521 are distributed on end face 52 continuously.Two sides 5211 of each protruding 521 form the exiting surface 522 of light conductor 50 jointly.The maximum gauge of light conductor 50 sets according to the width of bottom surface 51.In the present embodiment, the ratio of the maximum gauge of light conductor 50 and the width of bottom surface 51 is 1:4.
Refer to Fig. 4, in this second embodiment, be with the difference of the first embodiment, light conductor 50 for xsect be the tri-prismoid of isosceles triangle.Wherein, the bottom surface 51 of light conductor 50 is side corresponding to the base of isosceles triangle, and end face 52 is the side that two waists of isosceles triangle are corresponding.
Refer to Fig. 5, in the third embodiment, be with the difference of the first embodiment, the projection 521 on light conductor 50 is xsect cylinder arcuately.All arcwall faces of protruding 521 form the exiting surface 522 of light conductor 50 jointly.
Refer to Fig. 6, when spliced display device 100 shows, the light A that screen 30 sends near the position of rim area 31 enters light conductor 50 from incidence surface 511, and forms refracted ray A1 and reflection ray A2 there is refraction and reflection under the effect of the side 5211 of protruding 521 after.Refracted ray A1 directly penetrates from exiting surface 522.Reflection ray A2 in light conductor 50 through bottom surface 51 reflect and protruding 521 side 5211 refraction after form refracted ray A3.Refracted ray A3 penetrates from exiting surface 522.Light A through light conductor 50 refraction and reflect the center deviation of backward rim area 31.
When user watches the picture of display on screen 30 from different perspectives, the light that screen 30 sends near the position of rim area 31 is received by eyes of user after the refraction and reflection of light conductor 50.According to the reversibility of light, user can see the image that the part of screen 30 of both sides, display bezel district 31, rim area 31 shows.So, rim area 31 is visually reduced and even eliminates, and meets the visual continuity that user watches display frame, the overall display effect of picture shown by the screen 30 that improve spliced display device 100.
Those skilled in the art will be appreciated that; above embodiment is only used to the present invention is described; and be not used as limitation of the invention; as long as within spirit of the present invention, the suitable change do above embodiment and change all drop within the scope of protection of present invention.
