Abstract
The utility model discloses a side income formula backlight, including protection film, prism piece a, prism piece b, diffuser plate, cold cathode tube, cold cathode tube reflecting plate, light guide plate and reflecting plate, the protection film is installed on prism piece a, prism piece an installs on prism piece b, the prism piece b install on the diffuser plate, the diffuser plate is installed on the light guide plate, the light guide plate is installed on the reflecting plate, just the cold cathode tube reflecting plate is installed in the light guide plate left side, cold cathode tube reflecting plate internally mounted has the cold cathode tube. This side income formula backlight adopts injection molding's mode with the light guide plate, and its is fast, efficient, uses less LED crystalline grain, saves the cost, can creat more frivolous fuselage, reduce the holistic thickness of screen, create to straighten the machine that the following formula backlight is thinner and come, and simple structure, reasonable in design, low energy consumption and easily use widely.
Description
Technical field
The utility model relates to inflation film manufacturing machine technical field, is specially a kind of side-edge type backlight.
Background technology
Backlight is assembly indispensable in LCD, and one of its core texture is LGP. The light that the spot light of LGP or line source send injects behind LGP inside, is irradiated to the scattering netted dot generation scattering being positioned on bottom surface of light guide plate, and then point source or area source are converted to the upwards area source of transmitting, thereby provides backlight uniformly for LCD. Along with the development of lcd technology, the liquid crystal display particularly application of colour liquid crystal display device is also constantly being widened. Backlight (BackLight) is to be positioned at liquid crystal display (LCD) a kind of light source behind, and its illumination effect will directly have influence on LCD MODULE (LCM) visual effect. Liquid crystal display itself is not luminous, and its display graphics or character are its results to light modulation. Pulled by the market of liquid crystal display, backlight industry also presents a scene of prosperity. And backlight source module can be divided into according to the difference of light source setting position: direct-light-type backlight module and side-edge type backlight module, wherein, the sidepiece that side-edge type backlight module is arranged at LGP because of lamp bar makes the thinner thickness of backlight source module, is therefore applied in widely in liquid crystal indicator. And the large scale liquid crystal TV of a direct-light type LED backlight need to be used thousands of LEDs crystal grain, cost is relatively high, and power consumption is also a problem. Especially when early stage LED-backlit television set has just been released, improve color representation power with RGB three-color LED, make picture more bright-coloured, cost can be in any more naturally.
Utility model content
The purpose of this utility model is to provide a kind of side-edge type backlight, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of side-edge type backlight, comprise diaphragm, prismatic lens a, prismatic lens b, diffuser plate, cold-cathode tube, cold-cathode tube reflecting plate, LGP and reflecting plate, it is characterized in that: described diaphragm is arranged on prismatic lens a, described prismatic lens a is arranged on prismatic lens b, described prismatic lens b is arranged on diffuser plate, described diffuser plate is arranged on LGP, described LGP is arranged on reflecting plate, and described LGP left side is provided with cold-cathode tube reflecting plate, described cold-cathode tube reflecting plate inside is provided with cold-cathode tube.
Preferably, described LGP adopts ejection formation shape.
Preferably, described prismatic lens a adopts vertical direction to place.
Preferably, described prismatic lens b adopts horizontal direction to place.
Compared with prior art, the beneficial effects of the utility model are: this side-edge type backlight is by adopting LGP the mode of ejection formation, LGP is in the time of ejection formation, in propylene material, add the graininess material of a small amount of different refractivity, directly form densely covered microscopic bumps, it acts on just like site, its speed is fast, efficiency is high, use the LED crystal grain of less, save cost, can make more frivolous fuselage, in contrast to traditional backlight and can significantly it reduce thickness, and then greatly reduce the thickness of whole liquid crystal display product, for the further slimming of LCD product provides possibility, can create the machine thinner compared with straight-down negative comes, and simple in structure, reasonable in design, low energy consumption and be easy to promote the use of.
