Description
[technical field]
The invention relates to a kind of backlight module and adhesive frame structure thereof.
[background technology]
Existing backlight module is comprised of backboard (back bezel), LGP (light guide plate, LGP), light source, reflector plate, blooming piece, glue frame (frame) and housing.Wherein, LGP there is 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 the edge of backboard and LGP, finally again with the fixing encapsulation of housing said elements.
Wherein, the distance between light source and LGP can produce quite great impact with the uniformity (Uniformity) to the output briliancy (Luminance) of LGP with angle, if distance is excessive, 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 the scratch of LGP incidence surface or damage light source.When LGP and light source distance, when far away, it is more that the light utilization ratio can descend, thereby affect the quality of backlight module, and then become the decisive factor of the liquid crystal display that whether uses this backlight module.
Prior art is by Design Orientation mechanism on backboard, makes the assembling of light source and LGP meet the requirement of pinpoint accuracy.Yet, use the back plate design location mechanism can make between LGP and backboard one assembling spacing is arranged 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 invention provides a kind of adhesive frame structure of backlight module, be positioned at backboard and the location LGP, 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, make 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, make 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 because the tolerance that an assembling spacing is arranged between LGP and backboard exists, cause the position of LGP and light source to produce relative displacement, make the light utilization ratio can't fix the problem even weakened.
Below describe detailed features of the present invention and advantage in detail in embodiment, its content is enough to make any related art techniques person of haveing the knack of understand technology contents of the present invention and implement according to this, and, according to the disclosed content of this specification, claim and graphic, any related art techniques person of haveing the knack of can understand purpose and the advantage that the present invention is relevant easily.
