The specific embodiment
Behind the embodiment of consulting accompanying drawing and describing subsequently, the person of ordinary skill in the field just can understand other purposes of the present invention, and technological means of the present invention and enforcement aspect.
Please refer to Fig. 2, it shows the schematic diagram of a thin display 2 in the first embodiment of the invention.Thin display 2 comprises a guiding device 201, a panel 207, a reflector plate 209, a framework 210 and a blooming piece 211.Thin display 2 in the present embodiment has an arc external form, and arc curvature shown in the drawings only is an illustration, but not in order to restriction the present invention.
Framework 210 has two relative arc side frame 210a and two relative side frame 210b, guiding device 201, be arranged within the described framework 210, described guiding device comprises a LGP 203 and a light supply apparatus 205, wherein LGP 203 comprises one first arcuate flanks 203a, one second arcuate flanks 203b, an one top-surface camber 203c and a lower surface camber 203d, wherein top-surface camber 203c and lower surface camber 203d are connected with the first arcuate flanks 203a and the second arcuate flanks 203b respectively at its two side and constitute a three-dimensional arc LGP, and described first arcuate flanks 203a and the described second arcuate flanks 203b are arranged at respectively in the described two arc side frame 210a.
Of the present invention one is characterised in that light supply apparatus 205 is arranged at two arcuate flanks 203a, 203b one of them and described two arc side frame 210a between one of them.Particularly, in present embodiment, the light supply apparatus 205 of guiding device 201 comprises that (Light Emitting Diode, LED) led module of being formed is as light source, but not as limit by a plurality of light emitting diodes.A plurality of light emitting diodes in the present embodiment in the led module are equidistant and compartment of terrain setting along the first arcuate flanks 203a, for example light emitting diode 205a, 205b, 205c, 205d, 205e among Fig. 2, equidistant and the compartment of terrain setting along the first arcuate flanks 203a, but be not limited only to this, to reach the purpose of integral display uniform luminance.
In present embodiment, because the first arcuate flanks 203a of LGP 203 and the second arcuate flanks 203b are for being parallel to each other, and top-surface camber 203c and lower surface camber 203d have same curvature between two arcuate flanks 203a, 203b, therefore, help light supply apparatus 205 emitted light and fit and can directly be incident upon the second arcuate flanks 203b from the first arcuate flanks 203a, more even with the light that increase guiding device 201 is distributed on thin display 2.By this, the disclosed thin display 2 of the present invention can overcome the problem of the inhomogeneous and light leak of Luminance Distribution in the known technology.
