The width range that printing ink concentration is set is more than 1.2mm and is less than 1.5mm, it is contemplated that the oil blackeite area of quantum dot film layer 83 in actual production
Domain is 2mm or so, by Yellow ink concentration root on the shading rubber belt 70 in correspondence quantum dot film layer 83 oil blackeite region in the embodiment
Be set to 3 ranks according to the oil blackeite degree of quantum dot film layer 83, can match and effectively realize the colour mixture of display device fringe region, slacken or
Avoid oil blackeite phenomenon.
It refer to Fig. 3, the shading rubber belt sectional view that Fig. 3 provides for the present invention.Shading rubber belt 70 also includes black oil and inked
Brush layer 72, base material 73, wherein black ink printing layer 72 are in the side close to liquid crystal display panel 60, Yellow ink printing layer 71
Bring improvement that there is quantum dot using the shading glue of Yellow ink printing layer in the side close to backlight module 80, the present embodiment
The frame oil blackeite effect of the display device of film layer, will not additionally increase the Making programme of script display device, cost-effective, and this
Only improved by adding one layer of Yellow ink printing layer on shading rubber belt in application and apply the backlight of quantum dot film layer
Module frame oil blackeite problem, does not introduce new structure member, is advantageously implemented the lightening of backlight module, it is easy to promote.
The liquid crystal display panel 60 that refer in Fig. 1, the present embodiment also includes down polaroid 61, array base palte 62, color film
Substrate 63 and upper polaroid etc., backlight module 80 include glue frame 87 and the reflector plate 81 being arranged in glue frame 87, light guide plate 82, amount
Son point film layer 83 and optical diaphragm group, wherein quantum dot film layer 83 are arranged on light guide plate 82, and optical diaphragm group is arranged on quantum
In point film layer 83, optical diaphragm group includes the lower bright enhancement film 84 being cascading, diffusion barrier 85 and upper bright enhancement film 86 etc., this reality
Apply by setting diffuser plate 85 in example, light can be allowed to be uniformly distributed, the quantum dot film layer 83 and reflector plate of lower section can also be protected
81,.By setting upper bright enhancement film 84 and upper bright enhancement film 86 to reflect the light projected from diffuser plate 85, improve the angle point of light
Cloth, light is focused in positive angle, improves the luminous flux of positive angle, improves light utilization.
In order to which the quantum dot ensured in quantum dot film layer can be excited effectively, the wavelength of the light of luminescence unit is less than
Quanta point material be stimulated the specific wavelength sent light wavelength.In the present embodiment, luminescence unit uses blue light source,
Blue light source can be LED, CCFL or EEFL (External Electrode Fluorescent Lamp, external electrode fluorescence
Lamp) etc., the quantity of light source can be one or more, can be distributed in the one side or the multi-lateral of light guide plate.At present, the blue light of volume production
LED chip wavelength concentrates on 440-455nm scopes, and a width of 20nm of half-peak, the wavelength of light of blue light source is shorter, excitation quantum point
Efficiency it is higher.
Fig. 2 is refer to, the shading rubber belt 70 of liquid crystal display panel 60 and backlight module 80 is bonded generally along liquid crystal display
The edge of panel 60 is arranged at the non-display area 66 of liquid crystal display panel 60, is all set on shading rubber belt 70 in one embodiment
There is Yellow ink printing layer 71, so it is possible to prevente effectively from oil blackeite phenomenon occurs in each side of display device.
Yellow ink printing layer 71 is coated on the screening by modes such as flow coat, spraying, blade coating, transfers in one embodiment
On optical cement band 70, the making of the making of the Yellow ink printing layer compared with black ink printing layer in technology, it is easy to accomplish.
Display device in the application is by setting the shading rubber belt with Yellow ink printing layer, when quantum dot film layer side
When the light that edge region is passed through is partially blue, on the propagation path of light, blue light produces the effect of colour mixture with Yellow ink printing layer partially
Really, white is just can be appreciated that when people is observing display device, can so improves or avoid frame caused by blue light leak
The effect of oil blackeite, improves image displaying quality.Furthermore the Yellow ink concentration of Yellow ink printing layer is along from described non-display
Area is to the direction gradually step-down of the viewing area, and the color blending effect that can make whole fringe region evenly, improves image and show
Quality.Furthermore the application is brought using the shading glue of Yellow ink printing layer improves the side of the display device with quantum dot film layer
Frame oil blackeite effect, will not additionally increase the Making programme of script display device, cost-effective, and only by shading in the application
One layer of Yellow ink printing layer is added on adhesive tape improves the backlight module frame oil blackeite problem for applying quantum dot film layer, does not have
Have and introduce new structure member, be advantageously implemented the lightening of backlight module, it is easy to promote.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or using the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
