Abstract
The utility model discloses a kind of PCB substrate applied to reflective lamp bar and reflective lamp bars, reflecting ink layer is coated with for mounting the one side of LED lamp bead in the PCB substrate, it is circular black ink layer that profile is coated with around LED lamp bead on the reflecting ink layer.The utility model is by the black ink layer that is coated in PCB substrate, the problems such as some light of reflection from lens is absorbed, and is effectively improved bright spot, the speck of backlight module, so as to which uniform subjective picture be presented.
Description
Technical field
The utility model is related to LED technical field of liquid crystal display more particularly to a kind of PCB bases applied to reflective lamp bar
Plate and reflective lamp bar.
Background technology
LED liquid-crystal display is more environmentally protective relative to traditional CRT monitor, and low in energy consumption, and display effect is more
It is good, therefore gradually instead of CRT monitor.And one of the key component of backlight module for liquid crystal display, due to liquid crystal
Panel does not shine in itself, it is therefore desirable to which backlight module provides light source to realize that image is shown for liquid crystal display panel, and lamp bar is backlight mould
Important devices directly luminous in group.At present, direct-type backlight ratio shared in backlight module is increasing, with LED light
The lens type of pearl collocation is also more and more, and the direct collocation of wherein lens and LED lamp bead tends not to obtain preferable picture
Subjective effect, the problems such as bright spot, speck can be formed.
Utility model content
For the utility model in order to solve above-mentioned technical problem in the prior art, the utility model provides a kind of application
PCB substrate and reflective lamp bar in reflective lamp bar.
The technical solution adopted in the utility model is：
Reflecting ink layer is coated with for mounting the one side of LED lamp bead in the PCB substrate, is enclosed on the reflecting ink layer
It is circular black ink layer that profile is coated with around LED lamp bead.
The black ink layer encloses uniform black oil ink dot surrounded by least one.
The radius of the black oil ink dot different from the LED lamp bead centre distance is identical or black ink point radius in outer ring is big
In inner ring black ink point radius.
The position edge coating for being used to mount lens in the PCB substrate has bar shaped ink layer.
Using lamp bar reflective made of the PCB substrate, including：Be mounted on LED lamp bead in the PCB substrate and
Lens.
Compared with the prior art, the utility model has the advantage of：
By the black ink layer being coated in PCB substrate, some light of reflection from lens to PCB substrate is absorbed, is made more
The problems such as remaining light will not again be reflected by reflecting ink layer, the effective bright spot for improving backlight module, speck, makes backlight
Uniform subjective picture can be presented in module, carry high display quality.
Description of the drawings
Fig. 1 is the front view of the utility model；
Fig. 2 is that the utility model coats the vertical view after black ink layer；
Fig. 3 is that the utility model coats the vertical view after black oil ink dot；
Fig. 4 is that the utility model coats the vertical view after bar shaped ink layer.
Specific embodiment
Below in conjunction with the accompanying drawings and the principle and structure of the utility model is described in detail in embodiment.
Because lens can reflect on the reflecting ink layer of part light reflection to PCB substrate, above lens through reflectance ink
The problems such as forming bright spot, speck influences to show quality.
As depicted in figs. 1 and 2, one embodiment of the utility model proposes a kind of PCB substrate applied to reflective lamp bar,
PCB substrate 1 mounts the one side of LED lamp bead 2 covered with for reflecting the reflecting ink layer 4 of 2 light of LED lamp bead, reflecting ink layer
The square region that LED lamp bead 2 is avoided on surface centered on LED lamp bead 2 is coated with black ink layer 5 in square internally and round externally shape, passes through
Lens 3 are reflected into black ink layer 5 some light of PCB substrate or LED lamp bead 2 directly distributes light in PCB substrate 1
Absorb, make light will not secondary reflection so as to avoid bright spot, speck.
As shown in figure 3, two circle black oil ink dots 6, black oil are coated in the periphery centered on circular black ink layer 5
Ink dot 6 is uniformly distributed around central black ink layer 5 to be located in circular ring shape in lens coverage area, and on the big circular ring shape of radius
The radius of black oil ink dot is also bigger, the light that further absorption lens 3 reflects.In the present embodiment, black oil ink dot 6 is all located at
In the range of lens 3 cover, and black ink point radius in different annular it is identical also the scope of protection of the utility model it
In.
Black bar shaped is coated at lens 3 in corresponding PCB substrate 1 as shown in figure 4, against at the edge of attachment lens 3
Ink 7, black bar shaped ink 7 connect the two sides of PCB substrate 1.
The utility model also proposed a kind of reflective lamp bar using above-mentioned PCB substrate, also in the guarantor of the utility model
In the range of shield.Wherein reflective lamp bar as shown in Figure 1, including：PCB substrate 1, be pasted in PCB substrate 1 side by side serve as light source
LED lamp bead 2, lens 3 coordinate the surface for being mounted on LED lamp bead 2 centered on LED lamp bead.
The foregoing is merely a prefered embodiment of the invention, is not intended to limit the invention, it is all the present invention spirit and
It is former
All any modification, equivalent and improvement made within then etc., should all be included in the protection scope of the present invention.
