Abstract
The fluorescent powder slurry for plasma display comprises: 10~40 fluorescent powder body, 60~90 carrier, and 0.1~1 toluene to modify organic resin in carrier and enhance dissolving capacity to organic resin and make powder distribute evenly. This invention improves screening characteristics of slurry.
Description
Technical field
The invention belongs to the technique of display field, be specifically related to a kind of fluorescent powder slurry for plasma display.
Background technology
Thereby chromatic alternating-current plasma display is the ultraviolet ray excited fluorescent material that is coated in the display unit that utilizes geseous discharge to produce realizes colored the demonstration, be produced on the barrier on the rear panel, the display area is separated into little display unit, and order applies red (R), green (G), blue (B) three-color phosphor.Each display pixel is made of red (R), green (G), blue (B) three sub-pixels, and the visible light of three kinds of colors is realized panchromatic demonstration through addition colour mixture.Fluorescent material in each display unit not only is coated in the bottom of trench of barrier, also will be attached to the both sides of barrier, and fluorescent coating requires even compact.
Fluorescent powder paste material is dispersed in solid fluorescence powder particulate in the organic carrier and makes.As the compound that is used for above-mentioned fluorescent material of all kinds, known (Y, Ga) BO that glows that comprise
3: Eu
3+, Y

4: Mn
2+, the BaMgAl of blue light-emitting
10O17:Eu
2+Carrier is made up of organic solvent and organic resin, and organic resin plays the effect of binding agent, as ethyl cellulose, acrylic acid resin etc.; Organic solvent is used for dissolving organic resin, and commonly used have Terpineol 350, acetic acid diethylene glycol monobutyl ether, a diethylene glycol monobutyl ether etc.Existing organic resin the inadequate phenomenon of dissolving often occurs when dissolving in organic solvent.The powder of fluorescent material dispersed very poor in the inadequate carrier of organic resin solvent, and very easily produce the particle of secondary agglomeration.
In addition, at present fluorescent powder coated be the method that adopts silk screen printing mostly in the display unit.The position relative with each display unit on the through printing forme be hollow out, and other zone seals.Fluorescent powder paste material with certain viscosity is under the squeeze effect of scraper, be filled into above-mentioned through printing forme in the separated display unit of the corresponding above-mentioned barrier in hollow out zone, after fluorescent powder paste material drying, the sintering processes, carrier in the slurry evaporates, and has only on the inwall of fluorescent material powder attached to display unit.
When printing, the tension force that scraper presses down the through printing forme silk screen is uneven, and the tension force of scraper both sides is big, and the tension force in mid-way is little, because tension force is inhomogeneous, the amount that squeezes into the fluorescent powder paste material of display unit will be inhomogeneous thereupon.When display image, the display unit of fluorescent material different amts, sending visible light intensity can be different.And along with the expansion of substrate size, it is more obvious that this ununiformity can become.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of precision that can improve slurry output in the traditional silk-screened fluorescent material method is provided, improve the fluorescent powder slurry for plasma display of the full frame uniform luminance of display screen.
For achieving the above object, the preparation method that the present invention adopts is: containing mass fraction is 10～40 parts fluorescent material powder, 60～90 parts carrier and 0.1～1 part toluene.
Fluorescent material powder of the present invention is (Y, Ga) BO that glows
