Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
embodiment mono-
Known in conjunction with Fig. 3 to Fig. 6, the utility model provides a kind of straight-down negative to show module, comprise display module 104, backboard 101, be arranged on the reflector plate 102 of backboard 101 inner sides, be arranged on the luminescence component 103 of backboard 101 inner sides, display module 104 is positioned at the user oriented one side that described straight-down negative shows module, backboard 101 is positioned at the side that deviates from user that described straight-down negative shows module, reflector plate 102 comprises end reflector plate 1021 and the lateral reflection sheet 1022 that is positioned at end reflector plate 1021 surroundings and is connected with end reflector plate 1021, the angle of lateral reflection sheet 1022 and end reflector plate 1021 in obtuse angle, described angle is the angle that is positioned at reflector plate 102 inner sides, lateral reflection sheet 1022 inner sides are provided with at least one prism 105, as shown in Figure 3, prism 105 is arranged on lateral reflection sheet 1022 inner sides along the row or column direction of array of source, wherein, described array of source is that described straight-down negative shows the array that all light sources in module form.What certainly, prism 105 was also can be as shown in Figure 4 continuous is arranged on lateral reflection sheet inner side.
Prism 105 is prism, comprise an incidence surface and an exiting surface, belong to optically denser medium than air prism 105, so light can produce deviation to lateral reflection sheet after entering incidence surface, light after deviation can directive lateral reflection sheet, incides the exiting surface of prism after the reflection of lateral reflection sheet, also the direct exiting surface of directive prism 105, again there is deviation in light when the exiting surface, finally causes more dispersing that the light of directive prism 105 becomes.
For light is better dispersed, lateral reflection sheet inner side is provided with multiple prisms that are parallel to each other 105.
Thereby prism 105 can make the light of directive prism 105 produce more dispersing that refraction makes that light that optical module 103 sends becomes, reduce the light of display module fringe region described in directive, the brightness of the fringe region of display module is declined, therefore increased the light homogeneity that shows module.
Further, the drift angle of prism 105 can be that wedge angle can be also fillet, and preferred drift angle is fillet.
Detailed says, than wedge angle, fillet can make the light that is incident on top produce the more deviation of wide-angle, and larger to the change meeting of light path, the light that luminescence component 103 is sent is dispersed more.
Further, described luminescence component 103 comprises the light source 1031 being arranged on backboard and the reflective lens 1032 that is arranged on light source 1031 tops.
Because the reflective lens 1032 in light source is arranged on light source 1031 tops, so the region of the top of light source 103 needs the light of other light sources to realize the back lighting in this region.Straight-down negative shows that the light source 103 of module forms a light source display.As shown in Figure 6, inventor's discovery, the upper area of the light source at the edge of array of source of the prior art can form a dark space, at this moment because the light source at array of source edge has less adjacent light source, so cause the light source top at array of source edge can form a dark space, i.e. dark space n
The size of adjustment prism 105 and spacing can make the light directive dark space n of a part of directive prism 105.
Shown in Fig. 5, Fig. 6, light a, b that light source 1031 sends, reflector plate 1021 at the bottom of directive after reflective lens 1032 reflections, end reflector plate 1021 can be by light a, b secondary reflection again, the region that does not contain prism 105 of a light directive lateral reflection sheet 1022, through the secondary reflection again of lateral reflection sheet 1022, a light finally arrives the edge of display module 104; The prism 105 of b light directive lateral reflection sheet 1022, thereby prism 105 can make light b produce refraction makes light b incide on lateral reflection sheet 1022 with less angle, describedly littlely refer to that the incident angle when light b incides lateral reflection sheet 1022 in prior art is little.Light b finally arrives the dark space n of display module 104 through the reflection of lateral reflection sheet 1022, lateral reflection sheet 1022 can occur in the region joining of prism 105 and lateral reflection sheet 1022 to the reflection of light b, also can occur in is the lateral reflection panel region between prism 105.The light path of light b of the edge of prism 105 by the refraction of light b being made to directive display module 104 changes, the dark space n of final directive display module 104 after the secondary reflection again of reflector plate fringe region.
Make by the refraction action of prism 105 fringe region of directive display module 104 originally light b directive the dark space n of display module 104, this makes to show the brightness of fringe region of the high brightness of the display module 104 of the module brightness of the dark space n that has simultaneously improved display module 104 that declines to some extent at straight-down negative, thereby has improved the light homogeneity that shows module.
The utility model also provides a kind of display device, display device comprises that straight-down negative shows that straight-down negative shows that module comprises display module 104 described in module, backboard 101, be arranged on the reflector plate 102 of backboard 101 inner sides, be arranged on the luminescence component 103 of backboard 101 inner sides, display module 104 is positioned at the user oriented one side that described straight-down negative shows module, backboard 101 is positioned at the side that deviates from user that described straight-down negative shows module, reflector plate 102 comprises end reflector plate 1021 and the lateral reflection sheet 1022 that is positioned at all the other end reflector plates 1021 of end reflector plate 1021 surroundings and is connected, the angle of lateral reflection sheet 1022 and end reflector plate 1021 in obtuse angle, described angle is the angle that is positioned at reflector plate inner side, the inner side of lateral reflection sheet 1022 is provided with prism 105.Thereby prism 105 can make the light of prism 105 described in directive produce more dispersing that refraction makes that light that optical module sends becomes, reduce the light of display module fringe region described in directive, the brightness of the fringe region of display module is declined, therefore increased the light homogeneity that shows module.
The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
