Embodiment
Provide a kind of flat light source structure 100 according to one embodiment of the invention.See also Fig. 2 A and Fig. 2 B, Fig. 2 A is the schematic perspective view of the flat light source structure 100 main composition elements of present embodiment; To be that 100 groups of the flat light source structures of present embodiment are upright be the generalized section behind the backlight module to Fig. 2 B.The flat light source structure 100 of present embodiment mainly comprises one first substrate 110, one second substrate 120, a plurality of separation material 130 and a plurality of reverberation 150.Wherein, first substrate 110 and second substrate 120 are the relative position setting, and in an embodiment, first substrate 110 or second substrate 120 can be the transparency carriers that is made of the nature of glass material or macromolecule material.On second substrate 120, more comprise a plurality of electrodes 122, for example cathode electrode 126 and anode electrode 124, when imposing a voltage, cathode electrode 126 can be done point discharge with anode electrode 124, forms the usefulness of visible light after can impelling.Then, separation material 130 compartment of terrains are arranged on second substrate 120 and towards first substrate 110, cause fixed electrode 122 discharge spaces and increase sealing reliability in order to separate each electrode 122, wherein, separation material 130 can be strip, bulk or column, and its shape does not influence main spirit of the present invention.Next, continue with reference to figure 2B, reverberation 150, for example by silver, titanium dioxide or plastics are constituted, utilization has suitable mode now, for example binds, modes such as fastening or clamping, in the position with respect to separation material 130, is arranged on first substrate 110.In Fig. 2 B, illustrate, for flat light source structure 100, the blooming piece 140 of present embodiment and the generalized section after other component sets is found into backlight module.At least one blooming piece 140, for example diffuser plate is arranged at the relative position on first substrate 110, wherein, reverberation 150 is arranged on first substrate 110 and towards blooming piece 140, and the height of reverberation 150 is not more than the distance between the blooming piece 140 and first substrate 110.Action principle about planar light source, be to utilize first substrate 110 and second substrate, 120 formed spaces to fill inert gas, and in the lower surface coating phosphor powder of first substrate 110, when causing electrode 122 on second substrate 120 to be subjected to voltage, carry out point discharge between anode electrode 124 and the cathode electrode 126, excited inert gas discharges ultraviolet light and phosphor powder effect, thereby sends the visible light 160 of specific wavelength simultaneously.Because the reflection efficiency of reverberation 150 is high than first substrate 110, therefore can effectively utilize effect repeatedly with reverberation 150, thereby increase the briliancy in dark line district 200, form the light source of stablizing and exporting liquid crystal panel equably to, the visible light 160 that is reflected or reflect by blooming piece 140 is via the uniformity of the whole optics of visible light 160 liftings.
Continue, see also Fig. 3 A to Fig. 3 E, be the schematic perspective view of the present invention according to the reverberation 150 of different embodiment.Reverberation 150 can be that geometry constitutes, for example plate (as shown in Figure 3A), pyrometric cone (shown in Fig. 3 B), triangular prism (shown in Fig. 3 C), circular cone, cylinder, semicolumn (shown in Fig. 3 D) or semicircle ball-type (shown in Fig. 3 E).The shape of reverberation 150 can be done variation according to the shape of separation material 130 (shown in Fig. 2 B), in the hope of reaching the purpose that fully acts on visible light 160 (not shown).In an embodiment, when reverberation 150 is shaped as when plate, as shown in Figure 3A, for making the light reflection good, the reflectivity of reverberation 150 needs the reflectivity greater than first substrate 110 (shown in Fig. 2 B).What is more, reverberation 150 not only can reflect visible light improves the optics briliancy, more can provide a support force to support blooming piece 140 (shown in Fig. 2 B) on it, and for example diffuser plate reaches the effect that prevents blooming piece distortion warpage.In this, Fig. 3 A to Fig. 3 E only represents reverberation 150 shapes of different embodiments of the invention, does not limit spirit of the present invention.
Comprehensively above-mentioned, provide a kind of flat light source structure according to one embodiment of the invention, utilize a plurality of reverberations, effective and the blooming piece reflection or the visible light effect of refraction reduce dark line and produce, and promote whole optics briliancy.Moreover, utilize a plurality of reverberations, support the blooming piece on it, can reach the effect of prevention blooming piece distortion warpage.Again, according to spirit of the present invention, the reverberation that designs suitable geometry is arranged at the relative position that has flat light source structure intermediate gap thing now and gets final product, and need not put in order the group displacement, the degree of integration height.
The above illustrates characteristics of the present invention by embodiment, its purpose is to make those skilled in the art can understand content of the present invention and implements according to this, and non-limiting claim of the present invention, so, all other do not break away from equivalence modification or the modification that disclosed spirit is finished, and must be included in the scope of claims.
