Description
[technical field]
The present invention relates to a kind of display device, particularly relate to a kind of display device of utilizing natural light.
[background technology]
Lcd technology has obtained very great development in recent years, and liquid crystal indicator has progressively replaced heavy CRT display device.Display panels itself is not luminous, so general liquid crystal indicator all will be made up of display panels and backlight.Have luminescent devices such as fluorescent tube or light emitting diode in the backlight, the power that the power of its consumption consumes much larger than display panels itself.Recently big screen display device more and more is set at outdoor, and to play outdoor advertising etc., this class display device is in the majority with the light emitting diode matrix formation.Along with display panels can do increasing, it also can be used in outdoor, but daytime is outdoor brighter, could make displaying contents as seen by very high backlight power.Therefore, how to reduce the power of backlight, even not using the backlight illumination is the direction that people make great efforts.
[summary of the invention]
An object of the present invention is to provide a kind of display device, it comprises: display panels; Optically focused mechanism; Reflection organization; Natural light is assembled to described reflection organization by described optically focused mechanism; Described reflection organization reflects the natural light of described gathering to described display panels; The incidence surface area of described optically focused mechanism is greater than described display panels area.
As optional technical scheme, described display panels constitutes one and shows anchor ring; Described reflection organization is taper; Described anchor ring surrounds described reflection organization.As further alternative technical scheme, described demonstration anchor ring is the polygon anchor ring that is made of a plurality of display planes; Described reflection organization is a pyramid; A plurality of sides of described pyramid are corresponding one by one with described a plurality of display planes.As further alternative technical scheme, described demonstration anchor ring is an anchor ring; Described reflection organization is a circular cone.
As optional technical scheme, described display device comprises light source, and described light source is being lighted the back throw light to described display panels.As further alternative technical scheme, described light source is arranged in the described reflection organization; Described reflection organization has transparent housing, and surface of shell has reflector layer.As optional technical scheme further, described housing is the one-way glass housing.
As optional technical scheme, described optically focused mechanism comprises convex lens.As further alternative technical scheme, described optically focused mechanism comprises the array that is made of a plurality of convex lens.
As optional technical scheme, described optically focused mechanism comprises concave mirror.
Compared with prior art, display device of the present invention can adopt natural light to illuminate display panels, reduces even cancel the use of light sources such as fluorescent tube, saves the energy.

[embodiment]
Please refer to Fig. 1, Fig. 1 has illustrated the schematic side view of the display device 10 of first kind of embodiment of the present invention.For making diagram distinct, in the Figure of description complementary elements such as support frame are not illustrated.The display device 10 of present embodiment comprises: display panels 13; Optically focused mechanism 11; Reflection organization 12; Described optically focused mechanism 11 assemble extraneous natural lights (as daylight) 15 to as described in reflection organization 12; Described reflection organization 12 can be a plane mirror, and its natural light 15 that reflects described gathering is to described display panels 13; The area of the incidence surface 115 of described optically focused mechanism 11 so just can make display panels 13 have the brightness that surpasses extraneous natural light greater than the area of described display panels 13.Consider the penetrance of display panels, the area of optically focused mechanism incidence surface preferably will reach more than 10 times of display panels area.Owing to introduce natural light, the display device of present embodiment just can realize showing under the situation that does not have traditional backlight.In the present embodiment, described optically focused mechanism 11 is convex lens.Because single convex lens are difficult to do too greatly, in another embodiment, optically focused mechanism can be by a plurality of convex lens forming arrays.In other embodiments, optically focused mechanism also can use concave mirror to assemble extraneous natural light to reflection organization through light path conversion.
Fig. 2 illustrates the schematic side view of the display device of second kind of embodiment of the present invention; Fig. 3 illustrates the schematic top plan view of display panels and reflection organization in the display device of second kind of embodiment of the present invention; Fig. 4 illustrates the side-looking diagrammatic cross-section of the display device of second kind of embodiment of the present invention.To shown in Figure 4, the display device 20 of present embodiment comprises: display panels 23 as Fig. 2; Optically focused mechanism 21; Reflection organization 22; The extraneous natural light 25 of described optically focused mechanism's 21 gatherings is to described reflection organization 22; The natural light 25 of the described gathering of described reflection organization 22 reflections is to described display panels 23; The area of the incidence surface of described optically focused mechanism 21 is greater than the area of described display panels 23.As shown in Figure 3, in the present embodiment, described display panels 23 constitutes one and shows anchor ring; As shown in Figure 3 and Figure 4, described reflection organization 22 is conical; The anchor ring that described display panels 23 constitutes surrounds described reflection organization 22.
As shown in Figure 4, display device 20 comprises light source 24 in the present embodiment, so that illuminate display panels 23 in natural light deficiency (for example night).Described light source 24 is being lighted the back throw light to described display panels 23.Described light source 24 is arranged in the described reflection organization 22; Described reflection organization 22 has transparent housing 223, and housing 223 surfaces have reflector layer, and the light portion reflecting part is passed.A kind of more common satisfactory housing 223 is the one-way glass housing.Comprise that at other in embodiment of light source, light source also can be arranged on beyond the reflection organization.
Fig. 5 illustrates the schematic top plan view of display panels and reflection organization in the display device of the third embodiment of the present invention.The display device 30 of present embodiment comprises: display panels 33; Optically focused mechanism (not illustrating); Reflection organization 32; Extraneous natural light is assembled to described reflection organization 32 by described optically focused mechanism; The natural light of the described gathering of described reflection organization 32 reflections is to described display panels 33; The area of the incidence surface of described optically focused mechanism is greater than the area of described display panels 33.In the present embodiment, described display panels 33 is to show anchor ring by the quadrilateral that a plurality of display planes 331 constitute.Reflection organization 32 is a rectangular pyramid shape, and a plurality of sides 321 of pyramid are corresponding one by one with described a plurality of display planes 331; The anchor ring that described display panels 33 constitutes surrounds described reflection organization 32.In other embodiments, display panel can be three limit types, pentagonal even more polygonal demonstration anchor ring, and this can adjust according to actual needs.
