In addition, by arranging projection and depression on reflection horizon, even if can ensure that the steam produced under the condition of high humility also can spread in time, the normal work of light guide plate can not be affected.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is that a kind of light that the utility model embodiment provides is concentrated and the light conducting plate structure schematic diagram of equal light.
Fig. 2 is the solar battery sheet structural representation that the utility model embodiment provides.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As depicted in figs. 1 and 2, a kind of light that the utility model embodiment provides is concentrated and the light guide plate of equal light, comprise bright enhancement film 1, diffusion layer 2, light guide plate 3 and the reflection horizon 4 set gradually from top to bottom, the lower surface indentation of bright enhancement film 1, in the lower surface of bright enhancement film 1, the xsect of each sawtooth is unequal-sided triangle 11.When backlight is in the process of work, xsect due to each sawtooth in bright enhancement film 1 lower surface is unequal-sided triangle 11, thus after ensureing that light is mapped to the serrated-surface of bright enhancement film 1, there is inner full-reflection, further minimizing is reflected back the light of light guide plate 3 part, increase the light being injected into bright enhancement film 1 inside, improve the utilization factor of light, further enhancing the backlight illumination of backlight.Wherein, the angular range of this triangle 11 drift angle is 130 ° ~ 150 °, and in two base angles of this triangle 11, the angular range at any one base angle is 15 ° ~ 30 °, but the utility model does not limit this, depending on concrete technology demand.
Meanwhile, the upper surface of bright enhancement film 1 is plane, and the upper surface of bright enhancement film 1 is provided with some supporting bodies 12, and the xsect of this supporting body 12 is triangular in shape, rectangle or polygon, and closely adjacent between each supporting body 12.Each supporting body 12 is also respectively equipped with a spherical microlens 13, and this lenticule 13 is made up of makrolon material.The intensity of makrolon material is higher, and anti-impact force is better, and have higher transparency, be therefore suitable for the material as lenticule 13, certainly, the producer also can select different materials according to actual conditions.The light disperseed from light guide plate 3 disposablely can be concentrated on positive view directions by the design of this lenticule 13, reduces the loss of luminous energy, its spotlight effect is strengthened, also saves production cost.
Further, diffusion layer 2 is made up of light transmissive material, is provided with fluorescent grain in diffusion layer 2.The producer can according to the needs of actual conditions, and select best light transmissive material, such as light transmissive material can select PMMA, PC or ABS etc. of printing opacity.This fluorescent grain 21 comprises white fluorescent particle, red fluorescence particle and blue-fluorescence particle, certainly, also can select reflective particle.The light emitted from light guide plate 3 spreads and comes by these fluorescent grains 21 from all quarter, further increases the uniformity coefficient of back light source brightness.
In addition, be also provided with a plane of refraction 22 at diffusion layer 2 upper surface, the refractive index of this plane of refraction 22 is greater than the refractive index of diffusion layer 2, and thus, when light enters plane of refraction 22 from diffusion layer 2, now, refraction angle will be less than incident angle.This plane of refraction 22 is laminated by some refractors 221, the refractive index of each refractor 221 is not identical, the refractive index of each refractor 221 increases progressively from top to bottom successively, the light of such different directions is when different refractors 221, the direction of light can be adjusted, improve the uniformity coefficient of back light source brightness, thus make light with subvertical angle injection refractor 221, further increase the brightness of backlight.
The utility model also has additional a solar battery sheet 31 at light guide plate 3 upper surface, make solar battery sheet absorb extraneous light and convert thereof into electric energy supply light guide plate to use, although it is not the main for electric original copy of mobile phone, but when light guide plate is in the duty of low pressure, solar battery sheet also can make light guide plate uniformly light-emitting, this project organization is simple, easy to use.User also under high light, can regulate the brightness of display screen by solar battery sheet 31, person easy to use normally uses.In addition, be also provided with some sites (not shown) at the lower surface of light guide plate 3, the formation process of this site can be printing, etching, light harvesting or decorates, and the utility model does not make restriction to this.Light reflects upper surface through site, thus improves reflection efficiency and the reflection strength of light guide plate 3, the brightness of backlight is increased, has saved manufacturing cost.
In addition, also should be provided with some protruding (not shown) and some depression (not shown) at the upper surface in reflection horizon 4, steam can be prevented at light guide plate 3 surface aggregation, even if ensure that the steam produced under the condition of high humility also can spread in time, the normal work of light guide plate can not be affected.
Principle of work of the present utility model is: first, and light injects light guide plate 3, and light guide plate 3 is by distribution of light uniformly area source, and its light reflection of directive can return in light guide plate 3 by reflection horizon 4, prevents light from leaking outside, to increase the utilization factor of light.Then, light arrives diffusion layer 2, and diffusion layer 2 pairs of light serve the effect of all light, makes the uniform light distribution of injection in light guide plate 3.Finally, light enters bright enhancement film 1, and passes through the effect of the some spherical microlens 13 on bright enhancement film 1, the light from light guide plate 3 disposablely can be concentrated, further increase the brightness of backlight and equal photosensitiveness.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
