Abstract
The invention provides a backlight module, a display device and a terminal. The backlight module comprises a reflective sheet. A light guide plate, a light source assembly and light blocking structures are placed at the upper end of the reflective sheet. The light emergent face of the light source assembly faces the light incident face of the light guide plate. The light blocking structures are placed on the left side of the light source assembly and on the right side of the light guide plate respectively. The backlight module further comprises double-faced adhesive tape which is used for pasting and fixing the reflective sheet and the light blocking structures. According to the backlight module, a sticking frame is replaced with the reflective sheet, the double-faced adhesive tape and the light blocking structures, the size of the backlight module is decreased to a certain degree, and the requirement for side narrowing of the backlight module is met; meanwhile, the punching process is conducted on both the light blocking structures and the reflective sheet, the injection molding process for the sticking frame and the punching process for the reflective sheet are replaced, and the process is simpler; in addition, the sticking frame is replaced by the light blocking structures, so that the structural composition of the backlight module is simplified, assembling is easier, and the production cost of the backlight module is reduced.
Description
Technical field
The present invention relates to field of display devices, particularly relate to a kind of backlight module, display unit and terminal.
Background technology
As shown in Figure 1, existing backlight module comprises reflector plate (1), light guide plate (2), light source assembly (3) and glue frame (4), and reflector plate (1), light guide plate (2) and light source assembly (3) are placed in glue frame.In actual applications, as shown in Figure 1, glue frame (4) possesses certain thickness, increase the size of backlight module to a certain extent, therefore, existing backlight module can not meet the demand on the day by day narrow limit of current backlight module, glue frame need be formed by Shooting Technique simultaneously, complex process.
Therefore, how providing a kind of novel backlight module to adapt to the day by day narrow limit of backlight module and to reduce costs demand, is those skilled in the art's technical problems urgently to be resolved hurrily.
Summary of the invention
The invention provides a kind of backlight module, display unit and terminal, this backlight module utilizes reflector plate, double faced adhesive tape and light-blocking structure to instead of glue frame, can adapt to the demand on the day by day narrow limit of backlight module.
The invention provides a kind of backlight module, in an embodiment, this backlight module comprises reflector plate, reflector plate upper ends light guide plate, light source assembly and light-blocking structure, faced by the exiting surface of light source assembly and the incidence surface of light guide plate, light-blocking structure is placed on the left side of light source assembly and the right side of light guide plate respectively, and backlight module also comprises double faced adhesive tape, sticking double faced adhesive tape fixation reflex sheet and light-blocking structure.
Further, the light-blocking structure material in above-described embodiment is consistent with reflector plate material, and may also be other flexibility can die-cut material.
Further, the light-blocking structure in above-described embodiment is shaped by clicking technique.
Further, it is attached that the light-blocking structure in above-described embodiment and described reflector plate first carry out double faced adhesive tape, then carry out outline die.
Further, the light-blocking structure in above-described embodiment and described reflector plate also can be made of one structure.
Present invention provides a kind of display unit, it comprises backlight module provided by the invention.
Present invention provides a kind of terminal, it comprises display unit provided by the invention.
The invention has the beneficial effects as follows: backlight module provided by the invention, utilize light-blocking structure, double faced adhesive tape adds sphere for glue frame, reduce the size of backlight module to a certain extent, meet the demand on the narrow limit of backlight module; Simultaneously, light-blocking structure and reflector plate adopt clicking technique jointly, replace the Shooting Technique of glue frame and the clicking technique of reflector plate, technique is simpler, in addition, utilize light-blocking structure, double faced adhesive tape adds reflection and substitute the effect of glue frame, simplify the structure composition of backlight module, assembling is more simple, reduces the production cost of backlight module.
Accompanying drawing explanation
