Novel narrow-frame backlight module

Abstract

The invention discloses a novel narrow-frame backlight module. The novel narrow-frame backlight module comprises an iron shell, a light source, an FPC and a light guide plate, the FPC is arranged on the inner back face of the iron shell, the light source is connected with the FPC and arranged on the FPC and is close to the inner end of the iron shell, and the light guide plate is arranged on the FPC and arranged on one side of the light source. According to the novel narrow-frame backlight module, by changing some structures in an existing backlight module, the FPC is reversely installed on the inner back face of the iron shell, therefore, the overall backlight module is attached more firmly, the area which needs to be shielded and is located in front of a lamp can be reduced, the thickness of a backlight frame can be overall decreased, the firmness of the overall backlight module and the narrow frame effect are improved, and the novel narrow-frame backlight module has a very excellentapplication prospect.

Description

technical field [0001] The invention relates to the field of backlight design for mobile phones, in particular to a narrow frame backlight module. Background technique [0002] At present, in the development of existing mobile phones, narrow bezels are the main development direction. The overall mobile phone requires a narrow bezel, that is, the backlight module inside the mobile phone also needs a narrow bezel for matching. [0003] In the prior art, if attached figure 1 As shown, the backlight is usually fixed in shape with an integral iron shell, and various components are added inside to make the backlight flat as a whole. In this process, the inner end of the iron shell usually has a glue position as a fixed position, and the FPC and the connected light source are pasted and fixed on the glue position through double-sided adhesive, so that the overall structure is firm and stable. [0004] However, at present, as the frame requirements become narrower and the overall ...

Problems solved by technology

[0004] However, at present, as the frame requirements become narrower and the overall structure remains unchanged, the width of the glue position can only be reduced to reduce the overall frame width, but if the glue position is too narrow, the FPC cannot be fixed well , resulting in poor stability of the overall structure, prone to a series of quality problems such as light leakage or misalignment

[0005] In addition, the processing of the light spot in front of the lamp is also the reason that affects the overall thickness. In the existing technology, because the front and upper part of the light source is FPC, the treatment of the light spot cannot be performed, and the treatment of the light spot can only be done after the FPC, so the overall area that needs to be covered when visiting the clinic If it is too long, the range is included in the non-visible area, that is, it belongs to the range of the border, which also affects the effect of the border
