Abstract
The invention provides a backlight module which comprises a light source, a light guide plate and a reflector plate. The light source is located on the side face of the light guide plate. The bottom face of the light guide plate is provided with a plurality of lattice points arranged at intervals. The reflector plate is attached to the bottom face of the light guide plate and covers the multiple lattice points. The reflector plate is a mirror reflector plate with a mirror reflection function. The backlight module is good in light emitting effect, the thickness of the module can be reduced, and ultrathin complete machine design can be achieved.
Description
Technical field
The present invention relates to lighting field, particularly relate to a kind of backlight module。
Background technology
Backlight module is divided into side entrance back module and down straight aphototropism mode set two kinds according to the difference of light source incidence position。Referring to Fig. 1, it is the structural representation of prior art sidelight type backlight module。Side entrance back module includes light source 101, is positioned at the reflector 102 of light source 101 periphery, reflecting plate 103, be positioned at the light guide plate 104 above reflecting plate 103, be positioned at the diffuser plate 105 above light guide plate 104 and be positioned at the prismatic lens 106 above described diffuser plate 105。In side entrance back module, general light guide plate 104 is individually be assembled apart in the backboard cavity of backlight module with reflector plate 103。Existing backlight module, it is generally required to the structural member of backboard or similar backboard, is then fastened togather backboard and reflector plate and diaphragm etc. by glue frame。Existing side entrance back module is it is generally required to backboard, relatively costly, and thickness is thicker, it is impossible to realize ultra-thin overall design。
Therefore, it is necessary to defect of the prior art is made further improvements。
Summary of the invention
An object of the present invention is in that to provide a kind of backlight module, and its illumination effect is good, and without backboard as supporting mechanism, reduces module thickness, it is achieved ultra-thin overall design。
The backlight module of the present invention includes light source, light guide plate and reflector plate, described light source is positioned at the side of described light guide plate, the bottom surface of described light guide plate has multiple spaced site, described reflector plate fits on the bottom surface of described light guide plate and covers multiple site, and described reflector plate is the mirror reflector plate with direct reflection function。
As one preferred embodiment of the invention, described reflector plate is pasted on the bottom surface of described light guide plate by colloid, and described colloid covers the bottom surface of described light guide plate and multiple site。
As one preferred embodiment of the invention, described colloid is OCA optical cement。
Beneficial effects of the present invention: compared with prior art, present invention have the advantage that
The backlight module of the present invention, illumination effect is good, and without backboard as supporting mechanism, it is possible to reduce module thickness, it is achieved ultra-thin overall design。
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme of the embodiment of the present invention, below the accompanying drawing used required during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings。Wherein:
Fig. 1 is the structural representation of prior art sidelight type backlight module；
Fig. 2 is the structural representation of the backlight module of one embodiment of the invention。
Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation。
" embodiment " or " embodiment " referred to herein refers to the special characteristic, structure or the characteristic that may be included at least one implementation of the present invention。Different local in this manual " in one embodiment " occurred not refer both to same embodiment, neither be independent or selective and that other embodiments are mutually exclusive embodiment。
Referring to Fig. 2, it is the structural representation of backlight module of one embodiment of the invention。Refer to Fig. 2。The backlight module of the present invention, it includes light source 1, light guide plate 2 and reflector plate 3, described light source 1 is positioned at the side of described light guide plate 2, the bottom surface of described light guide plate 2 has multiple spaced site 4, described mirror reflector plate 3 fits on the bottom surface of described light guide plate 2 by colloid 5, and described colloid 5 covers bottom surface and multiple site 4 of described light guide plate 2。
Described reflector plate 3 is the mirror reflector plate with direct reflection function。
In the present embodiment, described site 4 be shaped as arc surfaced, it can be adopt material with scattering diluent to be arranged on light guide plate by modes such as printings。
Described colloid is OCA (OpticallyClearAdhesive) optical cement or other similar has higher clarity and the colloid of can bond reflector plate and light guide panel material。
Please continue to refer to Fig. 2, the present invention by process the light guide plate 2 of site by colloid entirely fit on there is the reflector plate 3 of direct reflection function, described colloid 5 covers bottom surface and multiple site 4 of described light guide plate 2。Being broadly divided into two classes when light sends the light path after entering into light guide plate 2 from light source 1, the first kind is that light is beaten on the site 4 of light guide plate 2, and light can spread to all angles, thus destroying conditioned reflex, penetrates in the front of light guide plate, light 6 in Fig. 2；Equations of The Second Kind light is not beaten on site, on the reflector plate 3 have direct reflection function, direct reflection is there is through beating after colloid 5 directly through behind the bottom surface of light guide plate 2, occur total reflection inside light guide plate such as light, light scatters out after advancing up to forward to encounter site, light 7 in Fig. 2。
The present invention has the reflector plate of direct reflection function on entirely being fitted by the light guide plate processing site, utilizes the reflection characteristic of direct reflection to replace the total reflection inside light guide plate。And the light guide plate posting the reflector plate with direct reflection function has the intensity of himself, add the center of module, it is possible to cancel the whole backboard supporting construction as backlight, save cost, reduce module thickness. realize ultra-thin overall design。
Compared with prior art, present invention have the advantage that
The backlight module of the present invention, illumination effect is good, and without backboard as supporting mechanism, it is possible to reduces module thickness, it is achieved ultra-thin overall design, facilitates subsequent clients assemble, reduces bad in operating and assembling production process of light guide plate。
Described above has fully disclosed the specific embodiment of the present invention。It is pointed out that any change that the specific embodiment of the present invention done by one skilled in the art scope all without departing from claims of the present invention。Correspondingly, the scope of the claims of the present invention is also not limited only to previous embodiment。
