Abstract
The utility model discloses a direct type backlight module relating to the technical field of display devices. The direct type backlight module comprises a diffusion plate and a light source, wherein the light source is arranged below the diffusion plate, a cavity is formed between the light source and the diffusion plate, and a support wire is arranged below the diffusion plate and is used for supporting the diffusion plate. The utility model also discloses a display device. The support wire is used for replacing the bracket to support the diffusion plate, and therefore the direct type backlight module can avoid local hot spots caused by the diffusion plate when being oscillated, is convenient for assembly and is lower in cost.
Description
Technical field
The utility model relates to the display device technology field, particularly relates to a kind of down straight aphototropism mode set and display unit.
Background technology
As shown in Figure 1, comprise diffuser plate 1 and LED lamp bar 2 in the structure of existing down straight aphototropism mode set, and for supporting diffusion plate, generally adopt a plurality of supports 3 to realize the function that supports, quantity does not wait at 4 ~ 9.Yet the mode of this use stent support diffuser plate has following defective: the assembling of support is not only consuming time, the more important thing is, when diffuser plate was subject to shaking, diffuser plate and support contact position produced effect of stress easily, thereby produced the phenomenon of local speck.
Therefore, how to design a kind of ease of assembly for down straight aphototropism mode set, and the mode that can avoid producing the supporting diffusion plate of local speck when diffuser plate is subject to shaking is problem demanding prompt solution.
The utility model content

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Embodiment one
Such as Fig. 2, shown in Figure 3, present embodiment provides a kind of down straight aphototropism mode set, comprise diffuser plate 1 and light source, diffuser plate 1 is positioned at the top of backlight module, and in the present embodiment, light source is LED lamp bar 2, LED lamp bar 2 is positioned at diffuser plate 1 below, and diffuser plate 1 and LED lamp bar 2 form cavity between the two, and the light that formed cavity send for the LED lamp on the LED lamp bar 2 forms a spreading distance, so that light has had certain divergence when arriving diffuser plate.Be provided with blooming piece 6 on the diffuser plate 1, optical model sheet 6 can be the combination of the optical thin film that meeting is used in the backlight modules such as polaroid or prism film, quantity, kind and the arrangement mode of optical thin film in the blooming piece 6 is not made restriction in the present embodiment.The straight-down negative optics module of present embodiment also comprises backboard 7, and the sidewall of backboard 7 is provided with fixed structure 8, is used for fixed support line 4.
In the present embodiment, what be used for supporting diffusion plate 1 is Support Level 4, is positioned at diffuser plate 1 below.Support Level 4 is made by ceramic material, carbon fibre material, organic material, metal etc., is not construed as limiting at this material to Support Level 4, uses ceramic material as preferred material in the utility model.
In the present embodiment, why selecting ceramic material is because pottery has high tensile, wearability as Support Level, and can be transparent material, and the diameter of Support Level 4 is designed to be less than or equal to 0.1mm, both can satisfy the requirement of support strength, again can be because of the uniform potential risk of the too large and influential backlight module brightness of diameter.Fig. 7 a and Fig. 7 b do not carry out the picture effect figure that optical analog obtains to backlight module when adding Support Level and adding Support Level, can find out that by contrast Support Level does not almost exert an influence to the picture effect of backlight module.The abscissa of Fig. 7 a, Fig. 7 b and ordinate represent the coordinate take the geometric center of backlight module as initial point, the numeral size on the coordinate, and unit is mm.
The arrangement of Support Level can be parallel line type shown in Figure 4, can also be X-type shown in Figure 5 or Z-type shown in Figure 6, but the arrangement of Support Level is not limited to the above, so long as can be applied in the utility model the arrangement mode that diffuser plate and blooming piece provide a supporting role.When mounted, the fixed structure that Support Level directly is fixed on the backboard gets final product, and therefore, can carry out easily the assembling of backlight module.
Concrete, described light source is not limited to LED lamp bar, and light source commonly used in other backlight modules can be used as light source in the utility model such as cathode fluorescent tube etc.
Embodiment two
Present embodiment two provide a kind of display unit (such as: liquid crystal display, Electronic Paper, oled panel etc. have the product of Presentation Function), comprise the one described backlight module such as embodiment.
As can be seen from the above embodiments, the utility model is by adopting Support Level to replace the stent support diffuser plate, can avoid the local speck phenomenon that causes when diffuser plate is subject to shaking, and easy to assembly, reduced cost.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
