Description
Technical field
This utility model belongs to screen display technology field, refers specifically to a kind of novel backlight module.
Background technology
Liquid crystal display is passive light-emitting component, and display screen itself is not luminous, but illuminated by its back light system behind；Backlight and LCDs are combined and are constituted LCD MODULE.
Traditional backlight source module generally comprises some assemblies such as light source, reflecting plate, light guide plate, diffusion barrier and prism film, its operation principle is to utilize PMMA (being commonly called as acryl) transparent light guide plate, the line source pure color white light that will be sent by cold cathode fluorescent tube (CCFL), import and be diffused into whole plate face from lamella lucida end face, there is vertical reflection when light is irradiated to the reflective spot of light guide plate back up, penetrate forward from the plate face (work surface) straight with light source incidence face.But acrylic light guide plate is heated after making moist all can be stretched expansion, it is easy to deformation, cause squeezing bad by the LED being arranged on light guide plate side；And gram force light guide plate more Bao Yue great is heated after making moist and is more easily deformed, and more Bao Yue great more easy shape fracture in transport, installation, use procedure is impaired.Form the reflective membrane of backlight, PMMA leaded light is pulled, have the interval air layer causing light loss to exist between diffusion barrier, condensing film simultaneously, optical film more many integral light-transmittings rate also can reduce accordingly, it is big that these defects all cause existing backlight module light loss, even some touch group light loss reached more than 70%, increase power consumption and go the brightness of increase line light source, point source, and the increase of power consumption also can directly affect the stand-by time of mobile phone, panel computer.Simultaneously because acryl light guide plate is not easy to fix, existing reflective surface light is easily revealed, and will add totally enclosed metal stationary housings on backlight module.
Therefore, along with LCDs develops to ultra-thin super large, it would be highly desirable to develop more energy-conservation, ultra-thin, simple in construction, light projection efficiency is higher, will not the backlight board of liquid crystal screen of shape.
Summary of the invention
In order to overcome defect of the prior art, the purpose of this utility model is in that to provide a kind of energy-conservation, ultra-thin, simple in construction, and light projection efficiency is higher, will not the backlight module of shape.
The purpose of this utility model is achieved in that
A kind of novel backlight module, including reflector plate and LCD display, described reflector plate is disposed with quantum glass light guide plate, diffusion sheet one, composite membrane one, composite membrane two and diffusion sheet two；Described diffusion sheet two is positioned at below LCD display；Described quantum glass light guide plate side has been sticked LED lamp bar；Described quantum glass light guide plate includes integrated quantum pipe and glass light guide plate, and described quantum pipe is positioned at the incident side within described glass light guide plate；Described glass light guide plate includes glass substrate, and described glass substrate has light source incidence face, reflective surface and light source output face, and described light source incidence face is transparent surface, and reflective surface and light source output face are anti-dazzle, and reflective surface is provided with transparent reflective dot matrix.
This utility model is further arranged to: the outside of described LED lamp bar has been sticked heat conduction bar.
This utility model is further arranged to: the reflective spot on described reflective dot matrix is gradually increased by side, light source incidence face.
This utility model is further arranged to: be pasted with light-collecting prism film below described light source output face.
This utility model is further arranged to: be printed with reflective ink on other faces except light source output face and light source incidence face.
This utility model is further arranged to: the bottom of described quantum pipe is fixed on the surface of the internal incident side of described glass light guide plate.
This utility model highlights compared to existing technology and useful having the technical effect that projects the light come in and can only be clipped in the optical channel between reflective surface and light source output face and repeatedly reflect via white array reflective spot from light source incidence face, reflection also exports from light source output face, compared with printing reflective spot liner reflective membrane at front face liner diffusion barrier rearward again on acrylic light guide plate, condensing film, protecting film, the traditional backlight of cover last layer metal housing touches group again, monolithic light guide plate not only light loss is few, and the backlight module being made up of multiple optical element is instead of with a piece of glass light guide plate, decrease the transmitance that multilamellar coating materials causes low, the problem that light loss is big, it is thinned thickness, alleviate weight, reduce power consumption, improve brightness, than acryl light guide plate more resistant to high temperature, it is not easy deformation；By by one-body molded to quantum pipe and light guide plate, reducing production and assembly cost, and owing to quantum pipe can be dispelled the heat by glass light guide plate, therefore it is substantially reduced the temperature rise of quantum pipe, improves the life-span of quantum pipe.
