Abstract
The invention discloses an ultra-thin backlight module which comprises a dispersion plate and lighting tubes. A plurality of lighting tubes are mounted in parallel behind the dispersion plate, and a diffusion plate is mounted behind the light tubes. In the invention, a metal backboard with a corrugated structure is matched with a reflection piece, and light is mixed evenly before reflecting lightto the dispersion plate by utilizing a structure formed by the reflection piece and the metal backboard. Therefore, when the backlight module is actualized by using the metal backboard with the corrugated structure to match with the bent reflection piece, the distance between the dispersion plate and the lighting tubes can be properly reduced to achieve the effect of the ultra-thin backlight module.
Description
Technical field
The present invention relates to the back light model setting technology field, relate in particular to a kind of module ultra-thin backlight that is used on the LCD.
Background technology
Along with development of science and technology, lcd technology is more and more ripe, and TV is also from traditional kinescope liquid crystal display till now.LCDs is passive luminous display screen.Liquid crystal itself is not luminous, so LCDs needs module backlight that light source is provided.Come branch can be divided into the backlight and side module backlight in the end according to the position of light source.Side liquid crystal module backlight is used in small-medium size, and large scale is used end module backlight.Backlight because the light source of side is in the side, and is generally all thinner.And the backlight because backlight in the end is in the bottom, so the end is backlight all thicker.Can module backlight be all emphasized a disguise, and disguise just is used for watching outside liquid crystal display, see an important indicator of lamp shadow.Usually lamp is far away more apart from diffuser plate, and disguise is good more, and is near more apart from diffuser plate, and disguise is poor more.
In order to realize better disguise, existing implementation method all is a diffuser plate of selecting for use mist degree bigger, but permeability is just poor when the diffuser plate mist degree is big, so the light utilization efficiency of light source can be lower.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of module ultra-thin backlight that is used on the LCD.
For solving the problems of the technologies described above, the objective of the invention is to be achieved through the following technical solutions.
A kind of ultra-thin module backlight comprises diffuser plate, fluorescent tube, in the back of diffuser plate a plurality of fluorescent tubes is installed side by side, in the back of fluorescent tube diffusing panel is installed.
Wherein, described diffusing panel is a watt rib plate structure, comprises fin and groove.
Wherein, the fin of described watt of rib plate and groove are triangular structure.
Wherein, the fin of described watt of rib plate is that the groove of trapezium structure, watt rib plate is a triangular structure.
Wherein, the fin of described watt of rib plate and groove are trapezium structure.
Wherein, described watt of rib plate becomes sinusoidal configuration.
Wherein, it is characterized in that described watt of rib plate is made up of metal backing and reflector plate.
Wherein, reflector plate is white reflection sheet, silver-colored reflector plate or speculum.
Wherein, reflector plate is the multilayer film reflector plate with micro-structural.
Wherein, the pitch between described two fluorescent tubes equates with pitch between watt rib plate two fins.
Above technical scheme as can be seen, the present invention has following beneficial effect:
The present invention has used the metal backing of watt rib structure, cooperates reflector plate, and the structure of utilizing reflector plate and metal backing to form is evenly mixed before reflexing to diffuser plate with light.Therefore, when using the reflector plate of metal backing engage flex to implement module backlight, can suitably reduce the distance between diffuser plate and the lamp, to reach the effect of ultra-thin module backlight with watt rib structure.

Fig. 2 is the present invention's module embodiment 2 profiles backlight;
Fig. 3 is the present invention's module embodiment 3 profiles backlight;
Fig. 4 is the present invention's module embodiment 4 profiles backlight;
Fig. 5 is Fig. 4 light light harvesting effect schematic diagram.
The specific embodiment
For ease of the present invention is further understood, now reach specific embodiment in conjunction with the accompanying drawings and describe the present invention.
See also shown in Figure 1ly, comprising: diffuser plate 01, fluorescent tube 02, diffusing panel 03, in the back of diffuser plate 01 a plurality of fluorescent tubes 02 are installed side by side, in the back of fluorescent tube 02 diffusing panel 03 is installed; Diffusing panel 03 is a watt rib plate structure, and fluorescent tube 02 is positioned on watt rib plate fin, and the pitch between two fluorescent tubes equates that with pitch between watt rib plate two fins fin of watt rib plate and groove are triangular structure, and described watt of rib plate is made up of metal backing and reflector plate.
The difference of back light module unit structure and Fig. 1 only is that watt fin of rib plate is that the groove of trapezium structure, watt rib plate is a triangular structure among Fig. 2.
The difference of back light module unit structure and Fig. 1 only is that watt fin of rib plate and groove are trapezium structure among Fig. 3.
Back light module unit structure only is that with the difference of Fig. 1 a watt rib plate becomes sinusoidal configuration among Fig. 4.
Fig. 5 is Fig. 4 light light harvesting effect schematic diagram, when installing as figure, the light that fluorescent tube sends, in through the reflector plate reflection, light plays the effect of a local light harvesting at the recess of metal backing under the reflection of reflector plate, therefore the light at fluorescent tube position can be distributed to whole plane, that is to say, strengthen the not position of direct irradiation of fluorescent tube, make light enter diffuser plate and reach a pre-effect of uniform before.Therefore, use metal backing collocation reflector plate, can suitably reduce the distance between diffuser plate and the lamp, to reach the effect of ultra-thin module backlight with structure.
Wherein, as a kind of embodiment of the present invention, reflector plate can be the white reflection sheet;
Wherein, as another kind of embodiment of the present invention, reflector plate also can be silver-colored reflector plate;
Wherein, as another kind of embodiment of the present invention, reflector plate also can be the multilayer film reflector plate with micro-structural;
Wherein, as another kind of embodiment of the present invention, reflector plate can be other reflection also, as speculum.
More than being described in detail a kind of ultra-thin module backlight provided by the present invention, used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
