Description
[technical field]
The invention relates to a kind of backlight module and adhesive frame structure thereof.
[background technology]
Existing backlight module be by backboard (back bezel), LGP (light guide plate, LGP), light source, reflector plate, blooming piece, glue frame (frame) and housing form.Wherein, LGP have exiting surface, with respect to the bottom surface of exiting surface and the light incident sides that connects exiting surface and bottom surface.Blooming piece is disposed at light direction one side of the exiting surface of LGP; Reflector plate is disposed between the bottom surface and backboard of LGP; Light source is disposed at by the light incident sides of LGP; The glue frame is disposed on the edge of edge and LGP of backboard, loads onto with the housing fixed sealing more at last and states element.
Wherein, the distance between light source and LGP can produce suitable great influence with the uniformity (Uniformity) to the output briliancy (Luminance) of LGP with angle, if distance is excessive, then the light utilization ratio is poor.Generally speaking, in Element Design, can between LGP incidence surface and light source, set a spacing distance in case scratch of LGP incidence surface or damage light source.When LGP and light source distance were far away, it is many more that the light utilization ratio can descend, thereby influence the quality of backlight module, and then become the decisive factor of the LCD that whether uses this backlight module.
Prior art is through Design Orientation mechanism on the backboard, makes the assembling of light source and LGP meet the requirement of pinpoint accuracy.Yet, use the back plate design location mechanism to make an assembling spacing is arranged between LGP and backboard and produce certain tolerance, cause the light utilization ratio to fix, the assembling of light source and LGP can't be reached the requirement of pinpoint accuracy.
[summary of the invention]
In view of this, the present invention provides a kind of adhesive frame structure of backlight module, is positioned at backboard and the location LGP, and this adhesive frame structure has pliability, and it comprises glue frame body and at least one supporting piece.Glue frame body is positioned at the side of LGP, and supporting piece is positioned at glue frame body and extends towards the direction of LGP, and in order to support LGP, restriction LGP position makes LGP press close to light source.
The present invention also provides a kind of backlight module, comprises backboard, LGP and aforementioned adhesive frame structure.LGP is positioned at backboard, and adhesive frame structure comprises glue frame body and at least one supporting piece.Glue frame body is positioned at the side of LGP, and supporting piece is positioned at glue frame body and extends towards the direction of LGP, and in order to support LGP, restriction LGP position makes LGP press close to light source.
The adhesive frame structure that the present invention uses backlight module is divided into glue frame body and supporting piece, and supports LGP with the supporting piece that is positioned at glue frame body, restriction LGP position.Therefore solve and commonly use backlight module, cause the position of LGP and light source to produce relative displacement, the problem that makes the light utilization ratio fix even to weaken because of the tolerance that an assembling spacing is arranged between LGP and backboard exists.
Below in embodiment, be described in detail detailed features of the present invention and advantage; Its content is enough to make any related art techniques person of haveing the knack of to understand technology contents of the present invention and implements according to this; And according to content, the claim and graphic that this specification disclosed, any related art techniques person of haveing the knack of can understand purpose and the advantage that the present invention is correlated with easily.
