Fig. 2 is the exploded perspective view of the utility model liquid crystal indicator one embodiment.
The realization of the utility model object, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of backing structure.
With reference to Fig. 1, in one embodiment, this backing structure comprises diffuser plate 10, the reflecting plate 20 just arranged diffuser plate 10 and the light source 30 be located between diffuser plate 10 and reflecting plate 20, wherein, the light that reflecting plate 20 is launched for reflection source 30, diffuser plate 10 is for spreading the light transmitted from diffuser plate 10, and the distance between diffuser plate 10 and reflecting plate 20 reduces to the side away from light source 30 gradually from the one end at light source 30 place.
In the present embodiment, distance between diffuser plate 10 and reflecting plate 20 reduces gradually along with the increase of the distance to light source 30, namely one end being certainly provided with light source 30 of reflecting plate 20 has an inclined-plane being close to diffuser plate 10 and tilting to the side away from light source 30, on the one hand from the light that light source 30 is launched first can obtain when diffuser plate 10 part reflection (or total reflection) propagates into diffuser plate 10 again by the reflection of reflecting plate 20 than front once propagate into diffuser plate 10 time less incident angle, thus improve diffuser plate 10 the reflected light (light that the light launched from light source 30 at least just transmits from diffuser plate 10 through the primary event of reflecting plate 20 is reflected light) of the position away from light source 30 outgoing efficiency (in the present embodiment, the outgoing efficiency of light refers to that light transmition is to the ratio of the energy of part light reflected away from diffuser plate 10 during diffuser plate 10 with the gross energy of light), enhanced diffustion plate 10 is at the output intensity of the position away from light source 30, on the other hand from the light that light source 30 is launched through the reflections propagate of reflecting plate 20 to incident angle less when can obtain more parallel with diffuser plate 10 than reflecting plate 20 during diffuser plate 10, the higher outgoing efficiency of the light of further guarantee diffuser plate 10 in the position away from light source 30, therefore along with the increase of distance to light source 30, the outgoing efficiency of the reflected light of self-diffusion plate 10 outgoing becomes large, and along with the increase of distance to light source 30, the light transmition that light source is launched increases gradually to incident angle during diffuser plate 10, because when reflecting, the outgoing efficiency of the larger light of incident angle of light is lower, be totally reflected when the incident angle of light is greater than critical angle, therefore along with the increase of distance to light source 30, the outgoing efficiency of an emergent light of self-diffusion plate 10 outgoing (light that the light launched from light source 30 directly transmits from diffuser plate 10 is an emergent light) diminishes, so, increase to the side away from light source 30 from the energy of the reflected light of diffuser plate 10 outgoing from the side near light source 30, and reduce to the side away from light source 30 from the energy of an emergent light of diffuser plate 10 outgoing from the side near light source 30, the complementation mixing of reflected light and an emergent light makes from the light ratio of the overall outgoing of diffuser plate 10 more even, namely the line source 30 of side entering type can be formed the area source from diffuser plate 10 outgoing by this backing structure, thus meets the requirement of LCD TV to the homogeneity of backlight.
In addition, in the present embodiment, light source 30 uses LED light source, due to for LED light source, just the strongest to the luminous energy of the position of LED light source, and the lighting angle of LED light source has certain restriction, be the LED light source of 120 degree as used lighting angle, its in half light intensity angle (as 60 degree) the luminous energy that sends stronger, namely the light-emitting area of LED light source is fan-shaped, so, distance in the present embodiment between diffuser plate 10 and reflecting plate 20 reduces gradually along with the increase of the distance to light source 30, namely one end being certainly provided with light source 30 of reflecting plate 20 has an inclined-plane being close to diffuser plate 10 and tilting to the side away from light source 30, diffuser plate 10 is parallel to compared to reflecting plate 20, the area that reflecting plate 20 light-emitting area fan-shaped with light source 30 tilted is intersected is more, thus make reflecting plate 20 in the present embodiment can obtain the luminous energy more launched from light source 30, and then make the more luminous energy of light source 30 be reflexed to diffuser plate 10 uniformly by reflecting plate 20 to carry out diffusion outgoing, namely the line source 30 of side entering type can be formed the area source from diffuser plate 10 outgoing by this backing structure, thus meet the requirement of LCD TV to the homogeneity of backlight.
Distance between the diffuser plate 10 of the backing structure that the present embodiment provides and reflecting plate 20 reduces to the side away from light source 30 gradually from the one end at light source 30 place, make this backing structure the line source 30 of side entering type can be formed area source from diffuser plate 10 outgoing when there is no light guide plate, thus make to use the LCD TV of this backing structure compared to the LCD TV using traditional side entrance back structure, on the one hand, cost is reduced owing to saving light guide plate, the phenomenon because bad the caused complete machine of light guide plate is bad can be avoided on the other hand to occur, moreover, the packaging technology of LCD TV is simplified due to the installation steps of saving light guide plate, improve packaging efficiency.
