Description
Technical field
The utility model is related to backlight more particularly to a kind of backlights having structure novel.
Background technology
Backlight (BackLight) is a kind of light source positioned at the behind liquid crystal display (LCD), its illumination effect will be straight
It connects and influences LCD MODULE (LCM) visual effect.Liquid crystal display itself does not shine, it show figure or it to light
The result of line modulation.Existing backlight is easy to receive electromagnetic interference, influences image quality.
Utility model content
The purpose of this utility model is that in order to overcome existing back light source structure complexity, image quality by electromagnetic interference influence
Problem creatively provides a kind of backlight.
To achieve the goals above, the utility model provides a kind of backlight, and the backlight includes display panel, with
And the luminescent layer on the inside of display panel, the pcb board of luminescent layer electrical connection control luminescent layer, pcb board are located at the interior of luminescent layer
Side, is equipped with isolating device between the luminescent layer and pcb board, the isolating device includes the magnalium that thickness is 0.03-0.05mm
EVA layer on the outside of alloy sheets and magnesium-aluminum alloy plate.
Further explanation to the utility model, it is hot-forming between the magnesium-aluminum alloy plate and EVA layer.
Further explanation to the utility model, the EVA layer thickness are 3-4mm.
Further explanation to the utility model is covered with a PP film layers on the inside of the pcb board.
It can be seen that since the utility model provides a kind of backlight, the backlight includes display panel, Yi Jiwei
Luminescent layer on the inside of display panel, the pcb board of luminescent layer electrical connection control luminescent layer, pcb board are located at the inside of luminescent layer, institute
It states and is equipped with isolating device between luminescent layer and pcb board, the isolating device includes the magnesium alloy that thickness is 0.03-0.05mm
EVA layer on the outside of plate and magnesium-aluminum alloy plate.The utility model is simple in structure, and isolating device has electromagnetic shielding and buffer insulation
Effect ensure that display quality is unaffected.
Description of the drawings
Fig. 1 is the structural schematic diagram of the backlight of the utility model；
Fig. 2 is the structural schematic diagram of the isolating device of the utility model；
The reference numerals are as follows：
Display panel 1, luminescent layer 2, pcb board 3, isolating device 4, magnesium-aluminum alloy plate 41, EVA layer 42, PP film layers 31
Specific implementation mode
In order to enable auditor to further appreciate that the structure, feature and other purposes of the utility model, in conjunction with appended
Preferred embodiment is accompanied by attached drawing, and detailed description are as follows, this attached drawing embodiment described is merely to illustrate the technology of the utility model
Scheme does not limit any form, size or ratio.
As shown in Figure 1, a kind of backlight provided by the utility model, the backlight includes display panel 1, and is located at
The luminescent layer 2 of 1 inside of display panel, the pcb board 3 of the electrical connection control luminescent layer 2 of luminescent layer 2, pcb board 3 are located at the interior of luminescent layer 2
Side, is equipped with isolating device 4 between the luminescent layer 2 and pcb board 3, the isolating device 4 includes that thickness is 0.03-0.05mm's
The EVA layer 42 in 41 outside of magnesium-aluminum alloy plate 41 and magnesium-aluminum alloy plate.
Hot-forming between the magnesium-aluminum alloy plate 41 and EVA layer 42,42 thickness of the EVA layer is 3-4mm, resiliency
It can be more preferable.
The inside of the pcb board 3 is covered with a PP film layers 31, not only dust-proof, moreover it is possible to antistatic.
It is to be understood that above-mentioned utility model content and specific implementation mode are intended to prove the provided skill of the utility model
The practical application of art scheme should not be construed as the restriction to scope of protection of the utility model.Those skilled in the art are in this practicality
It, can not various modifications may be made, equivalent replacement or improvement in novel spirit and principle.The scope of protection of the utility model is with appended power
Subject to sharp claim.
