The present invention relates to a laser color conversion microlens basal plate which at least comprises a basal plate and a microlens array, wherein the microlens array is formed on the basal plate, and the microlens array is provided with a plurality of microlens doping luminescent materials and /or phosphorescent materials. In addition, the microlens array can be composed of microlens array films or independent microlenses.
Description
Technical field
The present invention relates to a kind of lenticule base plate and microlens array thereof, be meant a kind of laser look conversion lenticule base plate and laser look conversion microlens array thereof especially.
Background technology
Two-d display panel is towards high brightness, complanation, light, the thin and trend development of economizing the energy in recent years, in view of this, (organic light-emitting display, OLED) panel becomes one of direction of utmost point desire development in the present opto-electronics in organic light emitting display.Organic electroluminescence display panel is the panel that a kind of autoluminescence characteristic of utilizing organic functional material (organic functional materials) reaches display effect, molecular weight difference according to the organic functional material, can be divided into micromolecule organic electroluminescence display panel (small molecule OLED panel, SM-OLED panel) with macromolecule organic electroluminescence display panel (polymer light-emittingdisplay panel, PLED panel) two big classes, in addition, the type of drive according to organic electroluminescence display panel also can be divided into active drive organic electroluminescence display panel (AM-OLED) and passive driving organic electroluminescence display panel (PM-OLED).
Because organic electroluminescence display panel utilizes the organic functional material to produce self luminous characteristic under the electric current perfusion, what self luminous color relation depended on the organic functional material can be with characteristic, and very many of employed organic functional material in the existing organic illuminated display element, comprise electric hole input horizon, electricity hole transport layer, luminescent layer, electron transfer layer, electron injecting layer, electricity hole limitation layer or the like, though can support utilization so the fluorescent material of many different colours and phosphor material are arranged, but in fact be subject to the restriction that the inner various organic functional materials of organic illuminated display element can be with coupling, organic illuminated display element can't at random be modulated easily, its color of conversion, often when attempting changing the glow color of organic illuminated display element, because element internal organic functional material can be with coupling not good, cause luminescence efficiency to descend, component life reduces.
In present organic illuminating element, fluorescent material and phosphor material are used for the organic functional layer or as the alloy of organic functional layer, use the luminescence efficiency of lift elements inside.Yet, though fluorescent material and phosphor material itself have good illumination efficiency, since also need in the use matched element inside the organic functional layer can be with characteristic, so in practical application, still have many restrictions, can't provide the convenience of element glow color conversion.
So United States Patent (USP) US5 in the prior art, 661,371 develop to add optical filter (colorfilter) or US5,869, the technology of additive color change medium (color change medium) provides the possibility of organic illuminating element glow color conversion beyond 929, but because optical filter or look change a large amount of radiation that layer itself also can absorber element be sent out injection moulding, so, adopt to add optical filter or look and change layer and also all can cause the organic illuminating element luminescence efficiency to descend no matter be.
On the other hand, because the light that organic illuminating element inside is produced can lose more than half part in the process that transfers to element-external, thereby lowered the external quantum efficiency of light-emitting component.
Existing solution is to utilize the mode that adds, and (Appl.Phys.Lett.76 (2000) p.1650) is attached to convex lens on the substrate light-emitting area of high index people such as Madigan, to increase outside quantum efficiency.As shown in Figure 1, being 2mm with diameter is attached on the light-emitting area of element 4 to the convex lens 41 of 3mm, if the material of convex lens 41 is identical with substrate 42, its element luminous flux can increase by 0.6 times to 1 times; If when using the convex lens 41 of high index, its element luminous flux can increase to 2 times.Be to use the oil plant (refraction index matching oil) that conforms to refractive index that lens are attached on the light-emitting area of element 4 in this, for limiting to some extent the serviceable life of element 4.
But too big, the thickness too thick (several millimeters) of the lens diameter that is used for increasing external quantum efficiency in the above-mentioned solution makes that the structure of whole element is excessive, and does not meet light, thin, short, the little trend of light-emitting component.Again, owing to use the oil plant that conforms to refractive index that lens are attached on the light-emitting area, causing peeling off of lens easily, so the serviceable life of element is not long, and is to satisfy the demand of organic illuminating element in the glow color conversion.
For fluorescent material and the phosphor material of breaking through element internal can be with the restriction of mating with the organic functional layer, and be the glow color of inverting element and the external quantum efficiency that increases integral body simultaneously, the present invention will provide a kind of " the laser look conversion lenticule base plate and laser look conversion microlens array thereof " that can solve this problem.
Summary of the invention
Because above-mentioned problem, the objective of the invention is to overcome the deficiencies in the prior art and defective, a kind of laser look conversion lenticule base plate and laser look conversion microlens array thereof are provided, so that fluorescent material and/or phosphor material can be broken through the restriction that the organic functional layer can be with, produce the effect of color conversion easily, and can promote external quantum efficiency and component life simultaneously, promote the applying value of existing different colours fluorescent material and phosphor material widely.
For reaching above-mentioned purpose, according to a kind of laser look conversion lenticule base plate of the present invention, comprise a substrate and a microlens array at least, wherein, microlens array is formed on the substrate, and microlens array has the lenticule of several mix a fluorescent and/or phosphoruses.
