The color restoration capability of (Liquid Crystal Display, LCD).
Quantum dot mixes red quantum dot and green quantum dot in the existing photoluminescent techniques application of field of display
It together in quantum dot film, other forms such as quantum dot stick in plastics, are made, or is by red quantum dot and green quantum dot
Hybrid package is then placed within before light source in glass tube, under the blue light excitation that blue LED issues, is generated red
Light, green light, and mixed in light guide plate together with blue light and form RGB three primary colors white light, the backlight for display.Quantum dot
With it is too close at a distance from light source, temperature is higher, influences the service life of quantum dot.The quantum dot of different-grain diameter is mixed, and
Specific fluorescence is issued under light source activation, can be generated fluorescence resonance energy transfer (FRET), be reduced phototransformation efficiency.Fluorescence is total
Vibration energy transfer refers to after donor molecule absorbs the photon of certain frequency through the interaction between donor-receptor dipole without spoke
That penetrates is transferred to neighbouring acceptor molecule, and showing as donor fluorescence intensity reduces and acceptor fluorescence intensity enhancing or quenching.So
It designs one kind to be not only avoided that heat of light source bring influenced but also can be reduced FRET, improves the quantum dot of phototransformation efficiency structure
Light guide plate has a very big significance.
Utility model content
The utility model be a kind of light guide plate, compared with the prior art for, the optical property of light guide plate can be optimized, avoided
Fluorescence resonance energy transfer improves the phototransformation efficiency of light guide plate, improves service life, and reduces the thickness of light guide plate, solves existing
Having in technology applies the manufacture difficulty in display field big quantum dot, the high technical problem of cost of manufacture.
The technical solution of the utility model is achieved in that
The incident side of a kind of light guide plate, including light conducting plate body, the light conducting plate body is equipped with quantum dot band, the quantum
Point band includes multiple grooves in array distribution, is respectively separated in the adjacent groove filled with red quantum dot and green amount
Sub- point.
Further, it is red to be dispersed in formation in organic solvent respectively for the red quantum dot and the green quantum dot
Color quantum dot filling liquid and green quantum dot filling liquid, the red quantum dot filling liquid and the green quantum dot filling liquid point
It does not fill and is solidificated in two adjacent grooves.
Further, the groove is provided on the light-emitting surface of the light guide plate, and the shape of the groove is circular cone, circle
One of column, pyrometric cone, cuboid, hemisphere, polyhedron or a variety of mixing.
Further, the organic solvent is one of UV glue, silica gel or resin.
From the above description of the utility model, it can be seen, compared to the prior art, the utility model has the advantages that
One, one of quantum dot is contained only in each groove of the utility model, containing red quantum dot or green quantum dot
Groove uniformly arrange in quantum dot band on light guide plate, under the blue light excitation of blue LED (LED), amount of red
Son point issues feux rouges, and green quantum dot issues green light, and the light of three kinds of colors, which combines, to form white light, and thus structure can be to avoid fluorescence
Resonance energy transfer, the service life for improving phototransformation efficiency, improving quantum dot.
Two, the utility model is filled by organic solvent and is solidificated in groove, so that the structure of the utility model is more
Simply, globality is more preferable, reduces the thickness of light guide plate and solves quantum dot in the prior art and applies in display field when system
Make that difficulty is big, the high technical problem of cost of manufacture.
