Description
Technical field
The invention relates to a kind of backlight module, refer to especially a kind of backlight module and its display unit of turning framework.
Background technology
Along with display technology progressive and evolution fast, liquid crystal display is mainly to utilize display panels to show now, because display panels belongs to the display floater of non-self-luminosity, therefore must supply briliancy the sufficient light source with being evenly distributed with backlight module, just can make the normal show image of display panels.In addition, audience is when watching display, and the narrower sense organ display effect of frame is better, and therefore narrow frame design becomes one of important demand of display.Yet, please refer to shown in Fig. 1, the width of the frame of light-emitting diode display comprises enclosing cover A6, backboard A7, glue frame A5, heat-dissipating frame A1, light emitting module A3 and the isostructural width of LGP A2, simultaneously, the width of frame also must comprise the required light mixing distance of light source of light emitting module A3, at this, the how narrow frame design of light-emitting diode display must add and consider from said elements.
Refer again to Fig. 1, is a kind of light-emitting diode display structure of side light-entering type of prior art, and it arranges LGP A2 and light emitting module A3 in heat-dissipating frame A1, then with glue frame A5 in conjunction with heat-dissipating frame A1, and utilize enclosing cover A6 and backboard A7 to be covered in glue frame A5.Wherein, light emitting module A3 is close proximity to LGP A2, the light that light emitting module A3 is penetrated directly enters LGP A2 and in display floater A4, shows, the heat-dissipating frame A1 lightguide plate fixing A2 and the light emitting module A3 that by metal material, make, the stability of provide heat radiation, fixing and guaranteeing light source.At this, in assembling process, in order to assemble smoothly LGP A2, must first LGP A2 be installed on heat-dissipating frame A1, upper in conjunction with glue frame A5 in heat-dissipating frame A1 again, avoid first assembling glue frame A5 and make the outstanding structure A51 of glue frame A5 shelter from the assembly path B1 ' of LGP A2, that is to say, the length distance of outstanding structure A51 surpasses the width of LGP A2 own, and LGP A2 cannot be placed on heat-dissipating frame A1 with level along assembly path B1 '.
Therefore, also there is a kind of heat-dissipating frame A1 to there is the outstanding structure (not shown) of carrying display floater A4, the effect narrowing down to replace the frame that is used to provide light-emitting diode display of glue frame A5 structure.Yet, because heat-dissipating frame A1 has the outstanding structure of carrying display floater A4, also cause the assembly path B1 ' that shelters from LGP A2, as previously mentioned, cause LGP A2 level to install.Therefore, how to solve existing problem, for the inventor of this case and the technical field person that is engaged in these relevant industries desire most ardently the problem of improvement.
Summary of the invention
Because the problems referred to above the invention provides a kind of backlight module, comprise LGP and framework; Framework has base plate, axial region and flip piece; Its middle shaft part is arranged at a side of base plate, and LGP is positioned on base plate, and flip piece is articulated in axial region, by this, flip piece is overturn between primary importance and the second place, vertical base plate in fact when flip piece is positioned at primary importance, parallel in fact base plate when flip piece is positioned at the second place.
The present invention also provides a kind of display unit, comprises display floater and backlight module, and backlight module comprises LGP and framework, and framework has base plate, axial region and flip piece; Its middle shaft part is arranged at a side of base plate, and LGP is positioned on base plate, and flip piece is articulated in axial region, by this, flip piece is overturn between primary importance and the second place, vertical base plate in fact when flip piece is positioned at primary importance, parallel in fact base plate when flip piece is positioned at the second place; Wherein, when flip piece is positioned at the second place, flip piece carries display floater.
In sum, the present invention utilizes pivot joint flip piece on framework, with the rotatable unlatching base plate of flip piece or block base plate, can ease of assembly LGP when opening base plate, and can be in order to carry display floater while blocking base plate, after replacing existing adhesive frame structure, also the display unit applicable to single-sided illumination, bilateral light inlet or four side light inlets is used, use the many sides of improvement and enter the light time, in structure, cause the difficult problem of assembling, can keep the narrow limit of frame, to have the effect of saving existing glue frame mould expense concurrently.
