Some embodiments of the present invention can be described in detail as follows.Yet except this was described in detail, the present invention can also be widely implements at other embodiment.That is scope of the present invention is not subjected to the restriction of the embodiment that proposed, and should be as the criterion with the claim of the present patent application.Moreover in this manual, the different piece of each element is not drawn according to size.Some yardstick is compared with other scale dependents and is exaggerated or simplify, so that clearer description and understanding of the present invention to be provided.
Fig. 2 and Figure 3 shows that a preferred embodiment of the present invention, Fig. 2 one have the schematic cross-section of the multiaspect formula liquid crystal indicator of positive 12 limit shape structures, and Fig. 3 is the three-dimensional structure diagram of Fig. 2.At first please refer to Fig. 2, have hollow and inwall to present the central heat sink element 210 of gear-like in the centre position of device.The inwall of the central heat sink element 210 specially usefulness of formative gear shape is intended to the stiffening device thermal diffusivity and uses as fixed sturcture, and Centromedian hollow part then can be used to place the control transmission circuit.In present embodiment, because the positive 12 limit shape structure utmost points level off to circle, so central heat sink element 210 also has a circular cross section, but central heat sink element 210 also can be oval, semicircle or other arbitrary shapes under other situations, but decides on the shape of multiaspect formula liquid crystal indicator.The material of central heat sink element 210 is good with the metal with high thermal conductivity, for example metal such as copper, aluminium.Then on the outer wall of central heat sink element 210, form a reflection horizon 220, be used for promoting the utilization factor of light source.Reflection horizon 220 generally is to fix formation in the mode that sheet metal is fitted on central heat sink element 210 outer walls, so reflection horizon 220 also has a circular cross section, or directly power in the outer wall of central heat sink element 210 and plate metal level, also can reach identical light reflecting effect.
Next, 220 the outside in the reflection horizon, the fluorescent tube 230 that does not wait along the uniform number of the arrangement of outer wall shape of central heat sink element 210 constituting a backlight assembly, and keeps a suitable spacing with reflection horizon 220.Multiaspect formula liquid crystal indicator of the present invention is as main light source configuration mode, so light need be through the light guide plate reflection, but directly or via directive exiting surfaces after 220 reflections of reflection horizon with direct type backlight assembly.In present embodiment, because positive 12 limit shapes are similar to circle, so fluorescent tube 230 needs only along the reflecting plate outside effect that evenly configuration can reach average light source distribution when arranging.But in other embodiments, can be according to different design shape, the centralized configuration light source in the subregion to reach specific brightness demand.
The outside at backlight assembly, then around arranging 12 plane liquid crystal panels 260 that size is identical, mechanically fixing between panel and the panel, to constitute dodecagon structure as shown in Figure 2, each display panels 260 and with being connected on drive unit 280 forms electrically, drive unit 280 is the both sides up and down that are positioned at central heat sink element 210, so be not shown among Fig. 2, the position of drive unit 280 sees also Fig. 3.At last, between backlight assembly and plane liquid crystal panel 260, then for utilizing framework 240 as fixing a plurality of multilayer optical film layers 250, framework 240 is fixed four limits of each multilayer optical film layer 250, therefore can not stop the light by multilayer optical film layer 250.In Fig. 2, because framework 240 is overlapping with a plurality of multi-layer thin rete 250, so display frame 240 not.The configuration purpose of these a plurality of multilayer optical film layers 250 effectively highlight, optically focused and light source evenly can be scattered.Since each thin layer 250 must with each plane liquid crystal panel 260 configured in parallel, so these a plurality of multilayer optical film layers 250 also are around configuration in 12 limit shape modes.Can comprise the functional membrane that one to two group diffuser plate, prismatic lens, diaphragm of one to two group or the like have additional function in each multilayer optical film layer 250, actual disposition quantity and kind are decided on actual demand.And in the outside of a plurality of multilayer optical film layers 250.
Fig. 3 is the three-dimensional structure diagram of the embodiment of Fig. 2, and each element is in layer pulled out from inside to outside so that the clearer demonstration than Fig. 2 to be provided.By the position that can see framework 240 among the figure.And except the above-mentioned element that has illustrated,, a stationary installation 270 that is used for fixing linear fluorescent tube 230 is arranged respectively also, that is the normal lampshade that uses in the backlight assembly in the both sides up and down of central heat sink element 210.This stationary installation 270 is except being used for fixing a plurality of linear fluorescent tubes 230, can also be expanded to and be used for fixing whole multiaspect formula liquid crystal indicator 200, stationary installation 270 in Fig. 3 can be fixed central heat sink element 210 by inside to outermost two-d display panel 260.In addition, described plane liquid crystal panel 260 is to be connected to the single or multiple device drive unit 280 of both sides up and down that is positioned at respectively, uses the driving show image.
By learning in the foregoing description, the present invention is different from the LCD of the single face or the two plane type of prior art, but adopt the assembling of multiaspect formula, and adopt the mode make each plane liquid crystal panel use a common backlight assembly, make via the light of reflective layer reflects and be not only the liquid crystal panel that offers dead ahead own, the light that many scripts can't be utilized, through using than liquid crystal panel contiguous about also can offering behind the wide-angle reflection, therefore promote light utilization efficiency greatly, that is to say with less light source configuration to reach the brightness identical with conventional art, this is of the present invention one big characteristics.In addition, number is many more when the limit of regular polygon, because the angle between panel and the panel is big more, makes device more level off to circle, is not easy to produce the dead angle on source reflection, and therefore better light utilization efficiency is also arranged.But for the device with low limit number form shape, for example a positive triangle also can utilize the mode that is disposed at privileged site that fluorescent tube is intensive, reaches the purpose that is evenly distributed light, and this is another characteristics of the present invention.
Except forming regular polygon, the present invention can also be used in the liquid crystal indicator of non-regular polygon.Figure 4 shows that another embodiment of the present invention, is one to have the multiaspect formula liquid crystal indicator schematic cross-section of non-regular polygon structure.Please refer to Fig. 4, one multiaspect formula liquid crystal indicator 400, its outermost constitutes an eight-sided formation by the 460 mutual connection arrangements of two groups of plane liquid crystal panels that vary in size, and its inner form identical with a last embodiment comprise a central heat sink element 410, be attached at reflection horizon 420 on the central heat sink element 410, a plurality of fluorescent tube 430, with a plurality of multilayer optical film layers 450 of a frame fixation, and do not show on Fig. 4, be positioned at the stationary installation and the drive unit of central heat sink element both sides about in the of 410.In the present embodiment, because the plane liquid crystal panel 460 that outermost is arranged still levels off to circle, so central heat sink element 410 still is best with the circle, all the other also all dispose according to the arrangement mode of plane liquid crystal panel 460 as a plurality of fluorescent tubes 430 and a plurality of multilayer optical film layer 450 and get final product.
Figure 5 shows that an embodiment more of the present invention, is one to have the schematic cross-section of the multiaspect formula liquid crystal indicator 500 of non-regular polygon structure.In this embodiment, be arranged in outermost liquid crystal flat panel 560 and present a sub-elliptical shape structure.Therefore, the shape of the central heat sink element 510 that it is inner is good with sub-elliptical shape person also, equate with suitable maintain reflection horizon 520 on the either direction, a plurality of fluorescent tube 530 and plane liquid crystal panel 560 triangular spacings, if central heat sink element 510 still is original circle, then easily form the phenomenon of insufficient light in the wide-angle knee of panel.And other are as the stationary installation that do not show on a plurality of multilayer optical film layers 550 and Fig. 5 etc., also need oval polygon-shaped the adjusting of fluid,matching Jinping faceplate panels 560.
And except suitable reflection horizon on the either direction, fluorescent tube and the triangular spacing of plane liquid crystal panel of remaining on, to avoid outside the light source inequality, the big or positions of panels of the turnover of, circular arc less when the angle between panel and the panel is when the distance of fluorescent tube is far away, can be relatively poor in its brightness effects of part panel near these positions, therefore on these certain location, can suitably dispose the fluorescent tube of a greater number, suitably to highlight.Up to the present cited embodiment is the example of 360 degree omnirange liquid crystal screen display units.In addition, device of the present invention also can be used in the multiaspect formula liquid crystal indicator that non-360 degree shows, as the part direction during for viewing area not, and the one side on the exterior wall for example.At this moment, the shape of central heat sink element then designs according to the liquid crystal panel of this device and geometric configuration that viewing area did not constitute, and reflection horizon, fluorescent tube and multi-layer thin rete only need be configured on the direction of liquid crystal panel and get final product.Because all fluorescent tubes still use a common reflecting plate, so the multiaspect formula liquid crystal indicator that non-360 degree shows has identical advantage and brightness effects with aforesaid omnirange multiaspect formula liquid crystal screen display unit.
Comprehensive above explanation as can be known, multiaspect formula liquid crystal indicator of the present invention, only with the backlight assembly of a group or lesser amt, can provide many group plane liquid crystal panels required light source simultaneously, and use a common reflecting plate to come reflection source, make the light that originally can't be utilized also can via wide-angle reflection near plane liquid crystal panel, promote light utilization efficiency greatly, not only reduce cost and be easy to and manufacture.And can be for the multiaspect formula arrangement mode of liberalization design, make LCD can present the arbitrary shape of regular polygon, non-regular polygon, ellipse or the like, promote the utilized field of LCD relatively, the occasion that particularly needs the large-scale demonstration fluorescent screen of high brightness, for example large-scale tv fluorescent screen, film or the advertisement plate on department store's exterior wall, and station internal information shows fluorescent screen etc.
Though the present invention describes with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, under the situation that does not break away from spirit of the present invention, also can make the variation and the modification of various equivalences, therefore, as long as variation, the modification to the foregoing description all will drop in the scope of claims of the present invention in connotation scope of the present invention.
