Description
Technical field
It shines uniform backlight module the utility model relates to backlight module field more particularly to one kind.
Background technique
Backlight module is one of the key part and component of panel of LCD, and function is well-off brightness and divides
The uniform light source of cloth can normally show that image, the illumination effect of backlight module will directly influence the view of liquid crystal display
Feel effect comprising light guide plate, LED light, diffusion sheet etc..Backlight module usually will appear the case where non-uniform light, such as go out
Existing hot spot, lamp eye intersect optical phenomenon, and the method usually solved in industry at present is black close to the side of socket patch in diffusion sheet
Item improves illumination effect with this.However, current light source is typically all the structure of short light path, in the side of diffusion sheet, patch is black
The booster action of item, secret note is smaller and smaller.Secret note is the strip of rectangle, and narrower in width, generally 0.3mm process
Scale error it is too big, thus worse and worse to luminous improvement.Moreover, patch secret note will increase the thickness of backlight module, and
And it is more wasteful artificial.
Therefore, the prior art is defective, needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, one kind is provided and is shone uniform backlight module, to change
The problem of kind backlight module non-uniform light.
The technical solution of the utility model is as follows: providing one kind and shines uniform backlight module, comprising: diffusion sheet and sets
Several LED light in the diffusion sheet side, the socket position that each LED light is corresponded on the diffusion sheet are equipped with the first ink
Area prints full ink in first ink area, is spaced a fixed gap between two neighboring first ink area.
Further, first ink area is rectangle, trapezoidal, triangle or arc-shaped.
Further, the ink is black ink or gray ink.
One kind shines uniform backlight module, comprising: diffusion sheet and several LED light set on the diffusion sheet side,
The diffusion sheet is equipped with the second ink area, and full ink is printed in second ink area, and second ink area is set to adjacent two
Gap location between the lamp of LED light between position and LED light and frame.
Further, second ink area is rectangle, trapezoidal, triangle or arc-shaped.
Further, the ink is black ink or gray ink.
One kind shines uniform backlight module, comprising: diffusion sheet and several LED light set on the diffusion sheet side,
The diffusion sheet is equipped with third ink area and the 4th ink area, and the third ink area is set to the socket position of each LED light
It sets, the 4th ink area is set to the gap location between the lamp of adjacent two LED light between position and LED light and frame, third oil
Full ink is printed in ink-covered area and the 4th ink area, the height of the third ink area is greater than the height of the 4th ink area.
Further, the third ink area or the 4th ink area are rectangle, trapezoidal, triangle or arc-shaped.
Further, the ink is black ink or gray ink.
Using the above scheme, the utility model corresponds to position ink for screen printing between socket or lamp on diffusion sheet, to solve to carry on the back
Optical mode group occur lamp eye, hot spot and intersect optical phenomenon, change it is traditional on diffusion sheet paste secret note by way of, not only
The illumination effect of backlight module can be improved, but also the thickness of backlight module can be reduced, because eliminating the work of patch secret note
Sequence, moreover it is possible to reduce the generation of foreign matter, to promote yield, while save artificial, saving cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model first embodiment.
Fig. 2 is that the first ink area is arc-shaped structural schematic diagram in the utility model first embodiment.
Fig. 3 is the structural schematic diagram of the utility model second embodiment.
Fig. 4 is the structural schematic diagram of the utility model 3rd embodiment.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Aiming at the problem that existing backlight module non-uniform light, the utility model provides one kind and shines uniform backlight mould
Group comprising diffusion sheet 1 and several LED light 2 set on 1 side of diffusion sheet, LED light 2 provide light source for backlight module.
Referring to Fig. 1, being the first embodiment of the utility model.In the present embodiment, corresponding each on the diffusion sheet 1
The socket position of LED light 2 is equipped with the first ink area 3, prints full ink in first ink area 3, adjacent two first ink area 3 it
Between be spaced a fixed gap, the distance in the gap is adjusted according to the spacing between adjacent two LED light 2.The ink is black oil
Ink or gray ink.When there is lamp eye phenomenon, by printing ink in socket position, dark ink has absorption effects, energy
Enough weaken the illumination effect at socket, and position does not print ink between lamp, will not weaken illumination effect, to avoid producing at socket
Raw lamp eye phenomenon, reaches the uniform purpose of vision area illumination effect.
It is corresponding that first ink area 3 is adjusted to rectangle, trapezoidal, triangle or arc-shaped according to the light emitting angle of LED light 2.
Referring to Fig. 2, being arc-shaped situation for the first ink area.
Referring to Fig. 3, being the second embodiment of the utility model, in the present embodiment, the diffusion sheet 1 is equipped with second
Ink area 4, second ink area 4 are set to the gap between the lamp of adjacent two LED light 2 between position and LED light 2 and frame
Place, second ink area 4 is interior to print full ink, and the width of the second ink area 4 is adjusted according to distance between the lamp of LED light 2.It is described
Ink is black ink or gray ink.When occurring hot spot phenomenon between lamp, by between lamp position off-set oil ink, weaken lamp between
Hot spot, and socket position is not printed, and illumination effect will not be weakened, to reach the uniform purpose of vision area illumination effect.
It is corresponding that second ink area 4 is adjusted to rectangle, trapezoidal, triangle or arc-shaped according to the light emitting angle of LED light 2.
Referring to Fig. 4, being the 3rd embodiment of the utility model, the diffusion sheet 1 is equipped with third ink area 5 and the
Four ink areas 6, the third ink area 5 are set to the socket position of each LED light 2, and the 4th ink area 6 is set to adjacent two
Printing in gap location between the lamp of LED light 2 between position and LED light 2 and frame, third ink area 5 and the 4th ink area 6
Full ink.The height of the third ink area 5 is greater than the height of the 4th ink area 6, and the ink is black ink or gray oil
Ink.When 2 socket of LED light lamp eye occurs with optical issue is intersected, at socket ink can be printed higher, between lamp
Ink is printed shorter by place, and dark ink has absorption effects, and the lamp eye phenomenon of socket is mitigated, and position is printed between lamp
Ink it is shorter, carry out transition, keep light balanced, to reach the uniform purpose of vision area illumination effect.
According to the light emitting angle of LED light 2, it is corresponding by third ink area 5 or the 4th ink area 6 be adjusted to rectangle, it is trapezoidal, three
It is angular or arc-shaped.
In conclusion the utility model corresponds to position ink for screen printing between socket or lamp on diffusion sheet, to solve backlight mould
Group occur lamp eye, hot spot and intersect optical phenomenon, change it is traditional on diffusion sheet paste secret note by way of, can not only
Improve the illumination effect of backlight module, but also the thickness of backlight module can be reduced, because of the process for eliminating patch secret note, also
It can be reduced the generation of foreign matter, to promote yield, while saving artificial, saving cost.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
