Abstract
The utility model discloses a backlight module with an upside-arranged diaphragm. The backlight module at least comprises a rubber frame, a bulge and a diaphragm layer; the bulge is fixed on the rubber frame; the diaphragm layer is formed by laminating multiple layers of diaphragms, and is arranged on the rubber frame, the multiple layers of diaphragms are provided with lugs at the same position, each lug is provided with a hanging hole hanging on the bulge; and an interval space is arranged between at least one part of the lug and the rubber frame. As the contact area of the lug and the rubber frame is reduced, the effect of the contact area on the light ray transmittance in the diaphragms is weakened, and the dark shadow phenomenon around the lug position of the diaphragms, severer than other positions, is reduced.
Description
Technical field
The novel field of liquid crystal display that relates to of this use particularly relates to the module backlight of interposed structure on a kind of diaphragm.
Background technology
Along with The development in society and economy, widely apply liquid crystal display (Liquid Crystal Display) panel in the electronic equipment.Because LCD panel itself does not have luminous function, thus a module backlight (back light module) must be provided below display panels, to provide liquid crystal panel required area source.Module backlight is one of most important parts in the liquid crystal display, directly influences the quality of liquid crystal pictorial display.The main composition parts of module backlight comprise light source (Light source), LGP (Light guide plate), reflecting plate (reflector) etc.; in order to improve optical effect; need simultaneously can be equipped with the plural layer optical thin film usually on the LGP, as diffusion sheet, brightening piece, prismatic lens etc.
In the existing module backlight, adopt interposed structure on the diaphragm usually.As described in figure one, multilayer diaphragm 101 generally is fixed on the glue frame 102, described multilayer diaphragm 101 all is provided with hangers 103, hangers 103 is provided with hanging hole 104, at the glue frame projection 105 is arranged fixedly simultaneously, hanging hole 104 hangs on the projection 105, and described hangers 103 is fitted on the glue frame 102, thereby realizes the location to diaphragm.
In the interposed structure liquid crystal module group backlight, hangers contacts with glue frame large tracts of land on existing diaphragm.Since glue frame and diaphragm all around contact the transmitance that can influence light in the diaphragm, can there be the shadow phenomenon around the diaphragm with around contacting of glue frame causes diaphragm, the hangers position is bigger owing to contacting relative area than other peripheral position of diaphragm and glue frame, therefore even more serious shadow phenomenon can occur on every side.This phenomenon shows as aspect the brightness and contrast inharmonious with other positions at display screen, influence spectators' viewing effect.
The utility model content
The purpose of this utility model is to provide a kind of module backlight, has alleviated near the shadow phenomenon even more serious than other position in hangers position of diaphragm.
The utility model provides a kind of new module backlight, comprise glue frame and membrane layer, described glue frame fixedly has projection, described membrane layer is arranged by the stack of multilayer diaphragm, described multilayer diaphragm all is provided with hangers in same position, described hangers is provided with hanging hole, and described hanging hole hangs on the described projection, described hangers have at least a part and described glue frame between be provided with clearance space.
Inventive point of the present utility model is, by between the part of hangers and glue frame, clearance space being set, make the contact area of hangers and glue frame less than the upright projection area of hangers on the glue frame, diaphragm all is directly to be fitted on the glue frame in the prior art, the contact area of hangers and glue frame equals hangers upright projection area on the glue frame, in the utility model, the contact area of hangers and glue frame reduces, thereby weakened the influence of contact area to light penetration in the diaphragm, and then alleviated near the shadow phenomenon even more serious than other position in hangers position of diaphragm.

The specific embodiment
Embodiment one
Present embodiment provides the module backlight of interposed structure on the diaphragm of a kind of structure shown in Fig. 2 A.In the present embodiment, module backlight comprises membrane layer 201, glue frame 202 and projection 205, projection 205 is fixed on the glue frame 202, membrane layer arranges for the stack of multilayer diaphragm, the multilayer diaphragm arranges a hangers 203 respectively at least, hangers 203 is separately positioned on the same position of each tunic sheet diaphragm, is provided with hanging hole 204 on the hangers 203 respectively.
The size of the size of described second step 205N and hanging hole 204 is complementary, and the size of first step 205M is greater than the size of hanging hole 204; Hanging hole 204 hangs on the second step 205N, thereby has realized the location to diaphragm.
Because the size of first step 205M is greater than the size of hanging hole 204, so can separate hangers and glue frame.Thereby between the part of hangers 203 and glue frame 202, clearance space 200 is set, and then reduced the contact area of hangers 203 and glue frame 202, thereby weakened the influence of contact to light penetration in the membrane layer 201, and then alleviated near the shadow phenomenon even more serious than other position hangers 203 positions.
The position of described first step does not limit, can be as Fig. 2 A, shown in Fig. 2 B.
Preferably, shown in Fig. 2 A, the size of first step is less than the size of hangers.
Preferably, projection 205 and glue frame 202 are structure as a whole, and are convenient to produce and assembling.
Preferably, first step 205M and second step 205N are structure as a whole, and are convenient to produce and assembling.
Present embodiment, to the number of plies of diaphragm, kind and overlay order are not done any restriction.
Embodiment two
Present embodiment provides the module backlight of interposed structure on a kind of structure diaphragm as shown in Figure 3.In the present embodiment, module backlight comprises membrane layer, glue frame 302 and projection 305, projection 305 is fixed on the glue frame 302, the stack of membrane layer multilayer diaphragm arranges, each tunic sheet is provided with respectively a hangers 303 is set at least, and hangers 303 is separately positioned on the same position of each tunic sheet, is provided with hanging hole 304 on the hangers 303 respectively, hanging hole 304 all hangs on the projection 305, thereby has realized the location of glue frame to diaphragm.
