Embodiment
Below the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
As shown in Figure 1, 2, screen 100 comprises display screen 101 and lens 102, screen 100 splicing construction comprises: light guide sheet 200 and fastening assembly, when two screens 100 splice, the edge docking of two screens 100, light guide sheet 200 is embedded between the edge of two screens 100, and the both sides of light guide sheet 200 contact with two screens 100 respectively, and two screens 100 are interconnected by fastening assembly.Use light guide sheet 200 fills up the gap between screen 100, prevents light leak, avoids screen 100 image to be destroyed, and the printing opacity of light guide sheet 200 own, there is some light to penetrate from light guide sheet 200, avoid screen 100 edge to occur non-luminous " black surround ".Two screens 100 connect by fastening assembly, make screen 100 edge clamp light guide sheet 200, avoid producing gap between screen 100 edge and light guide sheet 200, avoid light leak.Preferably, light guide sheet 200 selects soft or flexible material, can make up gap length change between the screen 100 that causes owing to expanding with heat and contract with cold, avoid light leak further.Preferably, light guide sheet 200 is made up of trnaslucent materials or scattering material, prevents light from light guide sheet 200 direct projection.
Light guide sheet 200 comprises the Embedded Division 211 and extension 212 that connect, and Embedded Division 211 is located between two screens 100, and extension 212 stretches out from the rear of screen 100.Wherein, Embedded Division 211 prevents the gap light leak between screen 100, screen 100 backlight is tackled by extension 212, two screen 100 backlights can not be interfered mutually, ensure display quality, particularly for rear projection screen 100, extension 212 can also avoid the light of the light source of two screen 100 correspondences to influence each other.Further, light guide sheet 200 is guide-lighting, and the light of light source can enter light guide sheet 200 by the side of light guide sheet 200, avoids causing " black surround ".
Light guide sheet 200 comprises the light guiding film of two stacked settings, and light guiding film can be installed in advance the edge of screen 100 when producing, when assembling at the scene, the screen 100 edge being pre-installed light guiding film splices, and reduces on-site installation work amount.Screen 100 edge that a side of light guiding film is corresponding with it glueds joint, and can prevent light guiding film from coming off, and light guiding film is connected closely with screen 100 edge, preventing light leak by glueing joint.
Fastening assembly comprises clench nail and frid 310, and frid 310 is provided with fluting 311, extension 212 be embedded in fluting 311 at least partly, two screens 100 connect and are installed on frid 310 by clench nail.Because the gap between screen 100 is very little, light guiding film is usually very thin, easily deforms, and fluting 311 pairs of light guiding film of frid 310 play support, spacing effect, make light guiding film all the time between two screens 100, do not interfere the normal display of screen 100.Screen 100 splicing construction also comprises two guide-lighting press strip 220, two guide-lighting press strips 220 be installed in fluting 311 and is clipped in the middle by extension 212.Because light guiding film is usually very thin, is difficult to put it into fluting 311 internal fixtion, after adding guide-lighting press strip 220, first fixes light guiding film by guide-lighting press strip 220, make light guiding film smooth, more guide-lighting press strip 220, light guiding film are installed on frid 310, handled easily.On the other hand, the printing opacity of guide-lighting press strip 220 own, does not hinder light to enter from the side of light guiding film.Preferably, the material of guide-lighting press strip 220 is harder than the material of light guiding film, is conveniently fixed light guiding film.As shown in Figure 3, fluting 311 has two relative cell walls, and one of them cell wall is more shallow than another cell wall, conveniently light guiding film is put into fluting 311.Screen 100 splicing construction also includes press strip folder 400, and press strip folder 400, by guide-lighting press strip 220 and light guiding film clamping, prevents guide-lighting press strip 220 from coming off from light guiding film, avoids loosening between guide-lighting press strip 220 and light guiding film.Frid 310 is provided with and lacks 312 with 311 yieldings be communicated with of slotting, and yielding scarce 312 is pressed from both sides 400 with press strip and mated, and can press from both sides 400 by dismounting press strip easily, being beneficial to and regulating when installing screen 100 by making a concession scarce 312.
Clench nail comprises screw assembly 322 and wire drawing 321, and screen 100 is provided with mounting hole, and the two ends of wire drawing 321 are each passed through mounting hole on two screens 100, and are fixed on frid 310 by screw assembly 322, and light guide sheet 200 is between wire drawing 321 two ends.Guide-lighting press strip 220 and light guiding film are clamped between frid 310 and screen 100 by clench nail, play spacing effect to guide-lighting press strip 220 and light guiding film.Guide-lighting press strip 220 one end, against the diapire of fluting 311, the other end against screen 100, makes screen frontside edge mutually align.
Each technical characteristic of above embodiment can combine arbitrarily, for making description succinct, all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this instructions is recorded.
Above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
