, embodiment described herein can combine with other embodiments.
In one embodiment of the invention, there is disclosed a kind of printhead modules for printing laser light source, comprising:
One or more print heads, for multiple laser light sources gradually to be printed or once printed on substrate；
Ink used by the printing includes luminescent dye and host material and solvent
For the embodiment: it, which is realized, first is made laser light source with inkjet printing, this is cheap and industry
Change manufacture laser light source and its various display devices or lighting device etc. provide a kind of new technical solution；Secondly as institute
It states multiple laser light sources and is easy to implement the module including the independent laser light source of multiple groups, allow for every group of laser light source module and shine
When, mutually can solely dissipate vertical, be difficult to generate laser coherence between emergent light, be led to greatly eliminate common laser coherence
The speckle phenomena of cause.
Wherein, referring to Fig. 1, it illustrates the print heads for the ink for being directed to different colours respectively, are used on substrate gradually
Print different light sources.Each print head has corresponded to a kind of ink of color.Referring to fig. 2, multiple print heads have corresponded to a kind of face
The ink of color.
In conjunction with Fig. 1,2, it is not difficult to find out that, above-described embodiment is complete, clearly describes: one or more print heads are used for
Gradually print on substrate or once print multiple laser light sources.
For the embodiment, referring to Fig. 1, when using a print head, print head gradually prints every group of laser light source
In each light source, such as according to R, G, B sequence gradually print three light sources of red, green, blue；It is more when using multiple print heads
A print head can once print each light source in every group of laser light source --- it is readily appreciated that, the number of print in work must
The quantity of light source being so more than or equal in every group of laser light source module, is greater than the quantity equal to tri- light sources of RGB.Fig. 2 only shows
Go out in multiple print heads and be directed to some light source, such as multiple print heads of red light source, for the more of another color
A print head is then not shown.
As can be seen that inkjet printing needs to print using ink.Corresponding with laser light source to be, the ink can be adopted
The polymer solution adulterated with laser dye.
In another embodiment, for the substrate, as long as being conducive to inkjet printing light source on it.More preferably
, substrate needs certain translucency.Illustratively, substrate can choose following any: (1) plating the silver mirror base of magnesium fluoride
Bottom；(2) distributed bragg reflector mirror (DBR) substrate etc..
In another embodiment,
The substrate needs to pre-process, including dot chart of the production corresponding to laser light source position on clean substrate
Case.
For the embodiment, the purpose for making dot pattern is convenient for carrying out the printing of light source according to pattern.
In another embodiment, the dot pattern is made by plotter.It illustratively, first will pretreatment
The substrate that (including the cleaning to substrate) is crossed is placed in the working region of plotter；Secondly, using the plotter in substrate
It is upper draw correspond to laser light source position dot matrix (remarks: being readily appreciated that, the dot matrix is a kind of array patterns, and the two exists
It is the different expression mode for identical concept in the present invention).Further, printhead module can be based on the array of production
Pattern prints laser light source.
It can easily be seen that the laser light source may need artificially to interfere its solidification process after printing each laser light source.
For the embodiment, natural solidification can be, be also possible to artificial solidification, wherein when spontaneous curing
Between cost it is often bigger, artificial solidification is then to accelerate cured process.For artificial solidification, can using pair
The mode (often constant temperature heating plate being used to be heated) of substrate heating, can also be using other appropriate solidifications similar to heating
Mode, such as light radiation (being irradiated including the light of ultraviolet light or other spectrum).Readily comprehensible, optional curing mode depends on
In ink.
It is furthermore preferred that in another embodiment,
The laser light source, for forming the independent laser light source module of multiple groups；
In every group of independent laser light source module, at least two light sources can issue different face under identical shooting condition
The light of color.
For the embodiment, this to can be achieved with the mixed of every group of laser light source module at least through two light sources
Color.Advantageously, it can be based on identical shooting condition in view of the embodiment, it is described to be excited by femtosecond laser
For light source, those skilled in the art can realize at least two light sources only by a kind of femtosecond laser of wavelength is used
Colour mixture.That is, at least two light sources can be excited by light beam, to realize colour mixture.
As can be seen that a plurality of light sources of inkjet printing are beaten by ink if printing a plurality of light sources
When print, a plurality of light sources are often microspheroidal, are hemisphericals specifically.In the process of printhead module work
In, the ink of used inkjet printing due to being liquid, prepared by light source be finally solid-state, then in ink jet printing process
Generally not contacting each other between each light source to avoid merging from each other.
That is, often not contacted between each light source, and there are spacing；If each light source is interpreted as hemisphere,
So for a plurality of light sources, the first hemisphere and the second hemisphere (or even with third hemisphere etc.) are nontangential each other.
, it is understood that in the colour mixture of at least two light sources, optionally, excited by femtosecond laser it is described at least
Two light sources, and if a branch of femtosecond laser only is used only, then this beam femtosecond laser can must be energized into simultaneously it is described
At least two light sources.So, since at least two light sources of one group of a plurality of light source can be under identical shooting condition
Issuing the light of different colours, it is assumed that a plurality of light sources are one group of laser light source module, such as triplets shown in Fig. 3,
It so can be realized as the colour mixture in every group of laser light source module using technology of the invention.Colour mixture is significantly example
As gone out a variety of different colors according to RGB three primary colors energy colour mixture.
It should be pointed out that the present invention allows at least two light sources of a plurality of light sources can be in identical excitation item
The light of same color is issued under part.For example, the strong light in order to realize certain solid color, then in every group of laser light source module
A plurality of light sources are also possible to identical light source, and each light source of a plurality of light sources can be under identical shooting condition
Issue the light of same color.This laser light source can be used for searchlight field.
In another embodiment,
The scale of the laser light source is grade, micron order or smaller.
For the embodiment, the scale of each light source is smaller, is more advantageously implemented the image of higher resolution
Display effect.If any one light source is considered as a micro- semiglobe, according to the requirement of resolution ratio, we can be made with
Micro- semiglobe of resolution ratio corresponding size.The size of micro- semiglobe of any one light source can be 15,35,45,
85,100 microns etc., even more small.If the size of micro- semiglobe of any one light source is grade, it is suitable for family
Outer Large Screen Display Technology.
As can be seen that the optical mode in micro- semiglobe is Whispering-gallery-mode, for various sizes of micro- semiglobe,
Its mode spacing is different.According to Whispering-gallery-mode theory, hemispherical diameter is smaller, and mode spacing is bigger, and gain section memory exists
Pattern count it is fewer, when pattern count is reduced to one, as single-mode laser obtains best monochromaticjty.
Further, the hemispherical diameter of micro- semiglobe corresponding to some light source is small arrives certain size, and described one
There are single-mode lasers when corresponding relationship, issued further to increase for the single-mode laser that scale cun goes out with the light source activation
Add the colour gamut section of laser.Illustrative rather than limitation, the certain size is about 15 microns.
In another embodiment, the size of the print head is determined by the size of each light source.
As can be seen that the size of print head is related to the hemispherical diameter of micro- semiglobe described previously, determined by hemispherical diameter
It is fixed.The optional range of the size of the print head has 5,10,20,30,40,50,60 microns etc..Compare micron if necessary to be made
The smaller micro- semiglobe of scale can be using the ink-jet that can adjust ink drop size when the size of print head can not be smaller
Printer, which carrys out adaptability, slightly to be improved in order to which light source of the present invention is made by inkjet printing.As previously mentioned, if
Obtain millimetre-sized micro- semiglobe, then the size of print head can with it is appropriate it is big a bit.
