Abstract
The utility model relates to a printed ultra-thin light guide plate, which includes a high-transparency plastic board, a plurality of printing ink layers forming refraction and reflection units which are arranged in the form of array on either the upper surface or the lower surface of the plastic board. A light solidifying printing ink layer containing nanomaterial is correspondingly covered on each printing ink layer, and the light solidifying printing ink layer has the function of uniform luminescence. By covering the light solidifying printing ink layer containing nanomaterial on each prior printing ink layer of the refraction and reflection units, the light guide plate has the effect of uniform luminescence, thus avoiding the occurrence of the scattering phenomenon of luminescence.
Description
Technical field
The present invention relates to the light guide plate that a kind of back light system is used, refer in particular to a kind of ink printing formula ultra-thin light guide board.
Background technology
Now, along with the technology such as electronics/communication products such as mobile phone, household electrical appliance is maked rapid progress, light guide plate is widely used in LCDs (the LiquidCrystal Display LCD) inside of various electronics/communication products, produce light source by the inner back light system of LCDs (as cold-cathode tube or light emitting diode), produce emergent light by this light guide plate guiding.
Generally speaking, the backlight processing procedure comprises two kinds of printing-type and non-printing-types, and non-printing-type is to adopt mould straight forming or compression moulding leaded light lines, and this technology and the application have nothing to do, and are not promptly described in detail at this.For printing-type backlight technology, can consult the disclosed a kind of ink printing type light guide plate of Chinese patent ZL03240962.1, at least one surface that discloses in the upper and lower surface of light guide plate is wherein arranged in this patent, printing-ink and form folding, reflector element, each folding, reflector element are array-like on the whole; And then by this printing-ink to light absorption after again through folding, the reflection mode carries out to external diffusion, because this diffusion is rambling astigmatic mode, can't guarantee uniformity of luminance, and the light transmission of existing printing-ink type light guide plate does not obtain and corresponding lifting yet, so, in order to be fit to the development of following light guide plate, how industry promotes the light transmission of light guide plate and guarantee luminously evenly seems particularly important.
Summary of the invention
The present invention is directed to the existing disappearance of above-mentioned prior art, fundamental purpose is to provide a kind of luminous uniform printed ultra thin light guiding plate.
Another purpose of the present invention is to provide a kind of printed ultra thin light guiding plate of high light transmittance.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of printed ultra thin light guiding plate, the plastic plate that comprises high transmission rate, be the printing ink layer that array-like is provided with a plurality of formation foldings, reflector element at least one surface in the upper and lower surface of this plastic plate, correspondence is coated with the printing ink layer that the solid type of a light contains nano material on above-mentioned each printing ink layer.
Above-mentioned each printing ink layer is arranged along be gradually close shape away from the incident light source direction near that side of incident light source by plastic plate.
The orthogonal projection on the plastic plate surface of above-mentioned each printing ink layer is square or rectangular or circular arc or polygon.
At least offer the breach that a tool polygon strengthens photosensitiveness at plastic plate side near incident light source.
The present invention compared with prior art, its advantage is as follows:
1, on the printing ink layer of existing each folding, reflector element so that the solid type of light that covers the luminous stepless action of another again contain the printing ink layer of nano material, make light guide plate reach luminous even effect, avoid the phenomenon generation of luminous scattering everywhere.
2, can conveniently carry out color modulation by two-layer printing-ink combination, wherein one deck is colourless merely, and another layer then is colored.
3, utilization can enlarge into optical cross-section area effectively at the breach inwall of offering near the plastic plate side of incident light source, and then realizes the purpose of high light transmittance.
4, be widely used in LCDs field such as electronics/communication products such as mobile phone, household electrical appliance.
Description of drawings
Fig. 1 is master's view plane structural representation of the present invention;
Fig. 2 is the cross section structure synoptic diagram of invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
See also Fig. 1, shown in Figure 2, a kind of printed ultra thin light guiding plate comprises the clear plastic plate 1 of high transmission rate, wherein:
Be the colourless printing ink layer 12 that array-like is provided with a plurality of formation foldings, reflector element on the upper surface 11 of this plastic plate 1, it is selected nano material for use and has the printing ink that microparticle forms astigmatism and adds by silk-screen or bat printing mode and give realization; Each printing ink layer 12 is arranged along be gradually close shape away from the incident light source direction near incident light source 2 sides by plastic plate 1; Correspondingly on above-mentioned each printing ink layer 12 be coated with coloured printing ink layer 13 that the solid type of another light contains nano material, by 13 equal light actions of this coloured printing ink layer, it equally also can add by silk-screen or bat printing mode and gives realization.And the orthogonal projection on plastic plate 1 surface of each coloured printing ink layer 13 is square or rectangular or circular arc or polygon (present embodiment is a circular arc).
Certainly,, also can offer the polygonal breach of a tool at least, to increase the sectional area that advances light at plastic plate 1 side near incident light source 2 for further strengthening its light transmission.
Design focal point of the present invention is on the printing ink layer of existing each folding, reflector element and then covers the printing ink layer that the solid type of another light contains nano material again, reaches the luminous even effect of light guide plate, avoids the phenomenon of luminous scattering everywhere to take place.
The above, it only is the preferred embodiment of a kind of printed ultra thin light guiding plate of the present invention, be not that technical scope of the present invention is imposed any restrictions, so every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any trickle modification, equivalent variations and modification that above embodiment did.
