Description
Technical Field
The invention relates to the field of backlight modules, in particular to a backlight module capable of avoiding inward collapse of a rubber frame.
Background
The traditional backlight module comprises a backlight source consisting of LEDs, light of the backlight source is converted into a surface light source through the backlight module to be emitted out, and the light is emitted out of the backlight module through the light uniformizing function of a diffusion sheet and can display images required by people after passing through a liquid crystal panel. Among the present backlight unit, it is fixed with the backplate to glue frame fixed adhesive tape, and this kind of fixed mode causes easily to glue four corners invaginations of frame, and the phenomenon that the Panel can't be placed in Panel retaining wall appears when dropping into MDL, leads to equipment frequent alarm, influences the normal input of module. The problem with this type of engagement is that:
the design of preventing caving in is not carried out in the four corners of backlight, produces the caving in easily at gluey frame block process, or because follow-up gluey frame contracts and the sticky tape viscidity descends and leads to gluey frame caving in, can produce very big influence to follow-up module lid screen.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a backlight module for avoiding the inward collapse of a rubber frame, and the specific technical scheme is as follows:
the utility model provides an avoid gluing backlight unit that frame is sunken which characterized in that: comprises a back plate (1), a rubber frame component (2), a first adhesive layer (3), a reflecting sheet (4), a light guide plate (5), a membrane material (6) and a second adhesive layer (7);
a first bending plate (8) is arranged upwards along the peripheral edge of the back plate (1), a reflecting sheet (4) is arranged on the inner surface of the back plate (1), the light guide plate (5) is arranged on the back plate (1) through the first adhesive layer (3), and the reflecting sheet (4) is positioned between the light guide plate (5) and the back plate (1);
the light guide plate (5) is provided with the film material (6), and the outer side of the middle part of each first bending plate (8) is provided with a second bending part (9);
the rubber frame assembly (2) is of a rectangular structure, the rubber frame assembly (2) is composed of four side frames, and a limiting boss (10) is arranged along the inner side edge of the rectangular structure;
two strip-shaped limiting blocks (11) are arranged on the outer edge of each frame side by side, a limiting groove (12) is formed in the outer side close to the frame, the limiting groove (12) is located between the two strip-shaped limiting blocks (11), and a limiting channel (13) is formed between the limiting boss (10) of the frame and the strip-shaped limiting blocks (11);
when the rubber frame assembly (2) is installed on the back plate (1), the first bending plate (8) is clamped in the corresponding limiting channel (13), and the second bending part (9) is located in the limiting groove (12).
To better implement the invention, the following steps can be further carried out: the first sticking layer (3) and the second sticking layer (7) adopt sticking glue.
The invention has the beneficial effects that: compared with the clamping mode of the rubber frame and the back plate of the common backlight module, the clamping mode of the rubber frame and the back plate is easy to cause the rubber frame to sink inwards in the clamping process, or the rubber frame sinks inwards due to shrinkage of the rubber frame and reduction of the viscosity of the adhesive tape in the subsequent placing process, and serious consequences are caused by panel breakage when the screen is covered due to serious sinking. The design adopts the hook design of the four corners of the rubber frame to effectively solve the problem of invagination generated during the combination of the rubber frame.
