Abstract
The utility model discloses a backlight module which comprises an optical membrane layer, a light guide plate, a light source, a reflective membrane and a frame. The light guide plate is arranged on the back face of the frame. A light source substrate is arranged on the side face of the light guide plate. After covering the light guide plate and the light source substrate, the reflective membrane is fixed on the back face of the frame. A protruding block is arranged at the edge of the optical membrane layer. A membrane groove and a fixing groove are formed in the front face of the frame, wherein the fixing groove is matched with the protruding block. The backlight module is installed on the frame through the protruding block arranged on the optical membrane layer, a shading double faced adhesive tape is not required to be used for fixation, the light emergent effect of the module is effectively improved, and therefore the uniformity of light emitting is ensured. In addition, assembly and disassembly are more convenient and rapid through the fixation mode of the protruding block and the fixing groove, a damaged optical membrane can be replaced at will, and cost is saved.
Description
Technical field
The utility model relates to lcd technology, particularly a kind of backlight module.
Background technology
Liquid crystal display (Liquid Crystal Display, be called for short LCD) because profile is frivolous, volume is little, low pressure is low in energy consumption, the advantage such as radiationless, be subject to people's favor, liquid crystal display is widely used in display screen or large-sized computer screen and the TV etc. of mobile phone, personal digital assistant at present, and more perfect display effect can be provided.Because liquid crystal display is non-photism display unit, need to could produce Presentation Function by backlight module, existing backlight module be edge with optical film by on the shading double faced adhesive tape fixed frame, cause the backlight module bright dipping inhomogeneous, affect the display effect of liquid crystal display.
The utility model content
The purpose of this utility model is to provide a kind of novel backlight module.
According to one side of the present utility model, a kind of backlight module is provided, comprise optical film, LGP, light source, reflectance coating and framework, LGP is located at the back side of framework, light source substrate is located at the LGP side, reflectance coating is fixed in the framework back side after covering LGP and light source substrate, and the edge of optical film is provided with projection, the holddown groove that the framework front is provided with the film groove and is complementary with projection.
In some embodiments, optical film comprises the optical brightening diaphragm (DBEF-M) that stacks successively, upper brightening piece, lower brightening piece and diffusion barrier, and the two ends of described optical brightening diaphragm, upper brightening piece, lower brightening piece and diffusion barrier are equipped with projection.Thus, can the cooperation by a plurality of blooming pieces increase the luminous intensity that of module, two ends are provided with projection can be so that optical film be more firm fixedly the time.
In some embodiments, the projection that is provided with of optical brightening diaphragm, upper brightening piece, lower brightening piece and diffusion barrier one end is larger than the projection that the other end is provided with.Thus, can increase the steadiness of optical film fixedly the time.
In some embodiments, the top of holddown groove is provided with the shading adhesive plaster.Thus, can remove the refractive power of projection from.
In some embodiments, light source comprises light source substrate and is located at a plurality of LED lamps on the light source substrate.Thus, more source energy-conserving and environment-protective of LED lamp.
In some embodiments, the side at the framework back side is provided with the mounting groove that light source substrate is installed.
In some embodiments, shading adhesive plaster surface is provided with the diaphragm of layer of transparent.
The beneficial effects of the utility model: the projection that the utility model is provided with by optical film is installed on the framework, no longer needs to use the shading double faced adhesive tape to fix, and has effectively improved the light effect that of module, and then guarantees uniformity of light.The other fixed form by projection and holddown groove so that mount and dismount more conveniently, can arbitrarily be changed the blooming piece of damage, saves cost.
