Description
Technical field
The utility model is related to backlight technical fields, specifically disclose a kind of glass backlight.
Background technology
Backlight is for ensuring that liquid crystal display sends out bright light supply apparatus, the brightness of backlight, the uniformity behind
There is direct influence to the correlated performance of liquid crystal display Deng some indexs.Backlight is generally by light source part and light guide section
It is grouped as, wherein light guide is mainly made of light guide plate, reflecting plate and the site that is set on light guide plate.The work of light guide plate
With the scattering direction for being guiding light, for improving the brightness of panel, and the uniformity of panel luminance is ensured.In order to promote panel
The bright uniformity forms site by way of printing or ejection formation in the bottom surface of light guide plate.Light is penetrated inside light guide plate
When on to site, reflected light can be spread toward all angles, then destroyed conditioned reflex and projected by light guide plate front, be dredged using various
Site close, not of uniform size can make light guide plate uniformly light-emitting.The purposes of reflecting plate is the light projected from bottom surface of light guide plate is anti-
It is emitted back towards in light guide plate, for improving the service efficiency of light.
Site on light guide plate is mainly formed by printing-type and non-printing formula, and it is special that the site of wherein printing-type has used
Optical ink light guide plate surface is formed in by way of printing.If forming site by way of printing, due to site
Small, printing difficulty is big, often occurs lacking site, generates the phenomenon that white point, needs to do over again to light guide plate, waste a large amount of work
When, product quality is difficult to ensure.Traditional reflector plate is mainly by the high resin material of the optical clarities such as PET or makrolon
It is foamed by fine, the density of bubble is higher, and reflectivity is higher.A piece of reflector plate price high-quality, that reflectivity is high is logical
Often all higher, material cost also becomes a problem for restricting backlight production development, how to reduce material cost, processing cost
As a direction of backlight technical field development.
Utility model content
Based on this, it is necessary to be directed to prior art problem, provide a kind of glass backlight, site on light guide plate can be reduced
Difficulty of processing promotes site producing efficiency and quality, and reduces reflector plate input cost.
To solve prior art problem, the utility model discloses a kind of glass backlight, including glass light guide plate, glass are led
Tabula rasa bottom surface is bonded with glass back plate, and glass light guide plate is provided with light directing site layer, guide-lighting net with glass back plate adjoining one side
Point layer is formed by several light guide ink points being sprayed in glass light guide plate one side, glass back plate side adjacent with glass light guide plate
Face is printed with white reflection ink layer, and LED light source is provided in glass light guide plate a side.
Preferably, light guide ink point is LGP light guide inks.
Preferably, pass through OCA optics glue stickings between glass light guide plate and glass back plate.
The beneficial effects of the utility model are：The utility model discloses a kind of glass backlight, and glass is made using glass
Light guide plate promotes backlight translucency and brightness, and light guide ink point is sprayed on glass light guide plate, is formd on glass light guide plate
Light directing site layer effectively promotes site producing efficiency and quality, not will produce white point.Using white reflection ink in glass back plate
On coated, formed white reflection ink layer, simple processing, reflecting effect is good, of low cost.Its is simple for production, site system
Make efficient, high-quality, replaces reflector plate using glass back plate, effectively reduce material cost, promote backlight board structure intensity, carry
Rise backlight brightness.
Description of the drawings
Fig. 1 is the cross section structure schematic diagram of the utility model glass backlight.
Reference numeral is：Glass light guide plate 1, glass back plate 2, light directing site layer 3, white reflection ink layer 4, LED light source
5。
Specific implementation mode
For that can further appreciate that the feature, technological means and the specific purposes reached, function of the utility model, below
The utility model is described in further detail with specific implementation mode in conjunction with attached drawing.
With reference to figure 1.
The utility model embodiment discloses a kind of glass backlight, including glass light guide plate 1, and 1 bottom surface of glass light guide plate is viscous
Be connected to glass back plate 2, glass light guide plate 1 and glass back plate 2 abut one side and are provided with light directing site layer 3, light directing site layer 3 by
Several light guide ink points being sprayed in 1 one side of glass light guide plate are formed, the one side adjacent with glass light guide plate 1 of glass back plate 2
It is printed with white reflection ink layer 4, LED light source 5 is provided in 1 a side of glass light guide plate.
Concrete principle is：On the light conduction that LED light source 5 is sent out to glass light guide plate 1, light is in light directing site layer 3
It is projected from 1 top surface of glass light guide plate under diffusion, forms the area source of brightness uniformity.Use glass light guide plate made of glass
1, light transmission is excellent, effectively promotes the brightness of backlight.By above spraying several light guide inks on one side in glass light guide plate 1
Point forms light directing site layer 3, and light directing site layer 3 is formed by way of spraying, promotes site producing efficiency, site is effectively ensured
Quality is generated without white point.Through 1 bottom surface of glass light guide plate project light under the reflex of white reflection ink layer 4
It is emitted back towards on glass light guide plate 1, promotes light utilization, promote backlight brightness.By the way that in glass back plate 2, upper printing is white on one side
Reflective ink forms white reflection ink layer 4, and instead of traditional reflector plate, simple processing, reflecting effect is good, at low cost
It is honest and clean, material cost is effectively reduced, backlight board structure intensity is promoted, promotes backlight brightness.
Based on above-described embodiment, light guide ink point is LGP light guide inks.LGP light guide inks have high briliancy, low colour cast,
High excellent in performance is spent together, sprays light guide ink point using LGP light guide inks, site precision height, the light conductivity of formation are strong.
Based on above-described embodiment, pass through OCA optics glue stickings between glass light guide plate 1 and glass back plate 2.OCA optical cements
Translucidus is strong, cementing strength is good, and cure shrinkage is small, using OCA optical cements that glass light guide plate 1 is be bonded with glass back plate 2
Get up, ensures that the stabilization between glass light guide plate 1 and glass back plate 2 is bonded, promote backlight translucency.
Above example only expresses a kind of embodiment of the utility model, the description thereof is more specific and detailed, but not
Can the limitation to the utility model patent range therefore be interpreted as.It should be pointed out that for the ordinary skill people of this field
For member, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this reality
With novel protection domain.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
