One of key part and component of crystal device.Backlight module mainly includes optical diaphragm, diffuser plate, LED light bar and fabric backplanes.
Because to be packed into the circuit units such as power supply, machine core, therefore whole present occurs that top is narrow, bottom for traditional liquid crystal TV behind bottom
Thick feature, globality is poor, and top gap is especially big when especially extension wall is placed, and appearance is poor.
Utility model content
The deficiencies of to overcome available liquid crystal TV behind globality poor, technical problem to be solved in the utility model
It is: a kind of down straight aphototropism mode set for being close to extension wall for realizing display device is provided.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
It is close to hang the down straight aphototropism mode set of wall for realizing display device, the backboard lower part of the display device is in indent
Thicker top optical cavity and relatively thin lower part optical cavity are formed between structure, with diffuser plate, circuit unit is located at concave inward structure, makes
The back side of display device forms a burnishing surface, is equipped with multiple LED light in the backboard, wherein being located at the LED in the optical cavity of lower part
Lamp is more more dense than the LED light being located in the optical cavity of top, to guarantee the uniformity of light mixing on diffuser plate.
Further, the LED light is the more LED light bars being horizontally set on backboard, wherein being located at lower part optical cavity
The spacing of LED light bar of the interior LED light bar than being located in the optical cavity of top is smaller.
Further, the spacing of the LED light bar being located in the optical cavity of top and the LED light bar being located in the optical cavity of lower part meets
Following relationship: D1/D2=N* (H1/H2), wherein D1 and D2 is respectively the spacing of upper and lower part lamp bar, and H1 and H2 are respectively
The thickness of top optical cavity and lower part optical cavity, N=0.5~2.
Further, the LED light uses the lamp bar of same form lens specification, it is all refractor or is all anti-
Penetrate lens.
Further, between the back side on display device upper backboard top and the structure back shroud outside circuit unit
Distance be 0~12mm.
The beneficial effects of the utility model are: by structure that backboard is arranged to lower part indent as circuit unit
Installation space, and the LED light of different concentrations is used cooperatively to guarantee the uniformity of diffuser plate light mixing, it is not influenced ensure that
Make the overall structure of display device more compact while display performance, integral thickness is thinner, and installation and patch are hung and be all more convenient
With it is firm, while also increasing the globality and ornamental value of display device.

Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, the utility model is close to hang the down straight aphototropism mode set of wall for realizing display device, described
1 lower part of backboard of display device is in that thicker top optical cavity 3 and relatively thin lower part light are formed between concave inward structure, with diffuser plate 2
Chamber 4, circuit unit 5 are located at concave inward structure, so that the back side of display device is formed a burnishing surface, are equipped in the backboard 1 more
A LED light, wherein the LED light being located in lower part optical cavity 4 is more more dense than the LED light being located in top optical cavity 3, to guarantee diffuser plate
The uniformity of upper light mixing.
Since liquid crystal display panel itself does not shine, the area source of the uniform luminance provided by backlight module is needed to come just
Often display image.LED light is made of lamp bead and corresponding lens, and lamp bead generates point source of light after energization, passes through the refraction of lens
Light is scattered with reflex, then forms the area source of uniform luminance by the homogenization of diffuser plate and optical diaphragm.
Traditional direct-light type LED backlight optical cavity cavity thickness are certain, and bottom needs loading circuit component behind TV, therefore
The form that top is thin, lower part is thick is integrally presented in LCD TV, and the big problem in top gap is presented when hanging wall, influences TV beauty,
As shown in Figure 3, Figure 4.
It is corresponding to adjust TV rear portion by using New-type mould group fabric backplanes for the straight-down negative display device of the utility model
The backlight optical cavity thickness of circuit unit allows backlight module that the feature that top optical cavity 3 is thick, lower part optical cavity 4 is thin is presented, is being put into circuit
After component 5, the form that top and the bottom are substantially flush comprehensively considers the integral thickness of display device and the size of circuit unit, described
The distance between structure back shroud 7 outside the back side on 1 top of display device upper backboard and circuit unit 5 can be controlled in 0~
Within 12mm, wall, TV morphological appearance can be close to after which is hung wall, while being also beneficial to the design of packaging material
And assembly.
Since distance of the LED light apart from diffuser plate is different in the optical cavity of top and the bottom, distance more dipped beam line range of scatter is smaller,
Brightness is resulted in reduce, therefore the LED light in lower part optical cavity 4 should arrange more more dense, just can guarantee on entire diffuser plate
The uniformity of light mixing.
It for LED light, is generally installed in the form of LED light bar 6, wherein best arrangement form is using more
The LED light bar 6 being horizontally set on backboard, wherein the LED light bar 6 being located in lower part optical cavity 4 is than being located in top optical cavity 3
The spacing of LED light bar 6 is smaller, quick come the uniformity enhanced convenience for guaranteeing light mixing by the spacing for adjusting LED light bar 6.
Specifically adjust LED light bar 6 arrangement form when, in the optical cavity of top 3 LED light bar 6 be located at lower part light
The spacing of LED light bar 6 in chamber 4 meets following relationship: D1/D2=N* (H1/H2), wherein D1 and D2 is respectively top under
The spacing of portion's lamp bar, H1 and H2 are respectively the thickness of top optical cavity 3 and lower part optical cavity 4, N=0.5~2.According to above-mentioned formula cloth
Setting LED light bar quickly can accurately guarantee the uniformity of light mixing on diffuser plate 2.
Further, the LED light uses the lamp bar of same form lens specification, is all refractor or is all reflection
Lens.Using the lens of same size compare using a variety of lens lamp bar scheme have lens type is single, standardize, give birth to
It produces convenient for control, the more low advantage of cost.
The utility model is matched by the way that backboard to be arranged to the structure of lower part indent as the installation space of circuit unit
The uniformity for guaranteeing diffuser plate light mixing using the LED light of different concentrations is closed, is made while not influencing display performance
The overall structure of display device is more compact, and integral thickness is thinner, and installation and patch extension are all more convenient and firm, also increases simultaneously
The globality and ornamental value of display device have good practicability and application prospect.
