Wherein, use optical fiber 100 backlight to cooperate light-emitting device 3, pointolite is converted to line source, again to concentrate a plurality of line sources, form an area source, replace the combination of general cold cathode fluorescent tube (CCFL) and light guide plate well, can the thick backlight module commonly used of 3～4mm will be generally originally, it is thick to be reduced to 0.15～0.4mm, help the slimming of LCD, more can reduce whole weight, more because the conduction of optical fiber 100 backlight is good, so the restriction on the size is little, so the range of size that can be suitable for is also big.
Secondly, because substrate 4 cooperates with optical fiber 100 backlight, when the material of substrate 4 and optical fiber 100 backlight is all soft body, backlight module 200 just has certain flexibility, cooperate plastic liquid crystal now, can provide new generation flat panel broad design, for example: as the thin display of file.
Also have,, more can produce following advantage by the combination of optical fiber 100 backlight with light-emitting device 3:
(1) safe;
(2) save the energy;
(3) no thermal source;
(4) bright and brightness is even;
(5) permanance is long;
(6) cost is lower;
(7) the more traditional sidelight optical fiber height of brightness.
Moreover the luminous mode of optical fiber 100 direct whole pieces backlight is come luminous, cooperates the reflecting effect of self, can reduce the transmission consume of light, allow illumination effect more comprehensively, reach with minimum power consumption, produce the effect of maximum luminous efficiency, can realize becoming the target of low-power consumption backlight module.
In above-mentioned, described light-emitting device 3 is one of following: other semiconductor lasers diode, light emitting diode, SMD light emitting diode.
With above-mentioned light emitting source, when being used for backlight module 200, advantages such as color rendition is good, power saving, the life-span is long, pollution is little can be arranged, as back light, can show chromatic colour more, colour gamut reaches 108%.
With the notebook is example, when using backlight module 200, with respect to the same notebook that uses cold cathode fluorescent tube (CCFL), under same brightness, can reduce the power consumption of about 1～5W, and the every reduction of its back light power consumption of notebook screen 1W, just about 30～45 minutes service time can be prolonged, further use this backlight module 200, can also allow screen possess more frivolous advantage, also tangible decline will occur on the volume and weight, allow product have the high competitive power of respecting.
In above-mentioned, the material of described substrate 4 is one of following: nonrigid plastic, rigid plastic, glass, acryl.
At different products, use different substrates 4, the characteristic of conversion backlight module 200 and the scope of application, producing best economic benefit, can be used for the screen that screen, acryl and glass that Electronic Paper, rigid plastic can be used for medium and small-sized can be used for large-scale or its above size as: nonrigid plastic.
Be the device block schematic diagram of the utility model liquid crystal indicator as shown in figure 11, shown in the figure, a kind of liquid crystal indicator 300, it comprises:
One backlight module 200;
One is located at the liquid crystal panel 400 of these backlight module 200 top side face;
This backlight module 200 is by a substrate 4;
A plurality of parallel to each other and coplines, be arranged in aforesaid substrate 4 end faces and optical fiber backlight 100 as claimed in claim 1; And
One is connected, can makes its luminous light-emitting device 3 to form with this optical fiber 100 backlight.
This light-emitting device 3 can convert the electric power by a mains supply 5 supplies to a light source, imports backlight module 200, makes the optical fiber backlight 100 in it shinny, fluid,matching crystal panel 400, but feed flow crystal device 100 can normally show running.
Can learn by above-mentioned, because use optical fiber 100 backlight, use as light guide, therefore do not need to be provided with the traditional backlight module the reflector that must be provided with, because optical fiber 100 backlight, itself just has reflective ability, thus can reach with liquid crystal indicator 300 dwindle, the target of attenuation, whole industry applications, practicality height.
In addition on the one hand, because whole structure is simplified, can also reduce cost, more because of the characteristic of optical fiber, the power consumption of light-emitting device 3 integral body is low, very helps energy-saving and carbon-saving, is better than traditional now backlight module and liquid crystal indicator.
It should be noted that at last: above embodiment is the described technical scheme of unrestricted the utility model in order to explanation the utility model only; Therefore, although this instructions has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of utility model, and it all should be encompassed in the middle of the claim scope of the present utility model.
