[embodiment]
Below, describe embodiments of the invention with reference to the accompanying drawings in detail.
Fig. 2 is the schematic diagram of ionic medium display floater plastic device of the present invention.
As shown in Figure 2, the plastic device of ionic medium display floater of the present invention is made up of plasticity stove (200), waveguide (240), microwave source device (250), voltage supply device parts such as (260).
At first observe plasticity stove (200), plasticity stove (200) is gone up and is formed substrate support platform (210), supports to comprise the heater (220) that heat is provided on the platform (210), and substrate is supported platform (210) to go up and deployed substrate (230).Start the inner heater (220) of plasticity stove (200), in certain plasticity temperature, carry out plastic engineering.Waveguide (240) connects plasticity stove (200) and microwave source device (250), and microwave is delivered to plasticity stove (200) from microwave source device (250).
Microwave source device (250) is the device that produces microwave, is a kind of oscillator that is called magnetron.Such magnetron produces microwave, and this microwave is that frequency is the following microwave of the above 3000MHz of 300MHz.At last, the device that provides microwave to produce the power supply that needs is provided power supplier (260).
As above, the lower support substrate (230) in the plasticity stove (200) can only utilize when providing microwave on the top of plasticity stove to be included in the plastic engineering that heat that substrate supports the heater (220) of platform (210) to produce forms pattern.Except the heat that heater (220) produces, microwave produces heat also can be used in plastic engineering, therefore can reduce and make actual plasticity temperature in the Plasmia indicating panel process but in the present invention.Simultaneously,, can reach design temperature at short notice, shorten the plastic engineering time because the microwave that microwave source device (250) produces is a utmost point ultrashort wave.
Utilize the manufacture method of the ionic medium display floater of the present invention that such plastic device forms as follows.
Fig. 3 is the manufacture method precedence diagram of existing Plasmia indicating panel.
As shown in Figure 3, the manufacture method of existing Plasmia indicating panel comprises: the front substrate manufacture process that list in the left side of Fig. 3; The manufacture process of the back substrate that list on the right side; In conjunction with the front substrate that forms by the front manufacture process and the process of back substrate.
At first introduce the front substrate manufacture process that list in Fig. 3 left side.After preparing front glass (300), form scan electrode on the front glass top of preparing and keep electrode (301).Such scan electrode with keep electrode and form by transparency electrode and bus electrode.It is as follows with the method for keeping electrode to form scan electrode, at first, utilize dry film to carry out lamination on the ELD top that forms by indium oxide (indium) and tin indium oxide ITO (Indium Tin Oxide) material, after photomask (Photo Mask) exposure that forms certain pattern, form transparency electrode by video picture and etching (etching) engineering.So the transparency electrode top that forms with silver (Ag) slurry with full frame mode of printing printing after, identically with the forming process of transparency electrode expose and form bus electrode.Then, when plasticity was carried out in the temperature heating about 550 ℃, transparency electrode and bus electrode were by integrated formation scan electrode and keep electrode.Form and such can't utilize plastic device of the present invention when keeping electrode, reason is that metal objects such as silver that microwave can cause forming bus electrode are melted and polluted panel.
So form keep electrode pair after, keep electrode pair top and form insulating barrier (302), comprising after spraying comprises the insulator slurry of glass powder on the front glass of keeping electrode pair, utilize the plastic device of ionic medium display floater of the present invention to form insulating barrier.At this moment, the plasticity temperature of plasticity slurry is more than 400 ℃ below 500 ℃, can carry out plasticity under than the low temperature of existing plasticity temperature.
(303) front substrate has just been finished after forming the protective layer that is made of magnesium oxide (MgO) on the insulating barrier of Xing Chenging like this.
Introduce the front substrate manufacture process of listing on Fig. 3 right side then.After equally preparing back surface glass (310) with the front substrate, on glass in the back, intersect to form addressing electrode (311) with the above-mentioned electrode pair of keeping.Such addressing electrode and the scan electrode of front substrate and to keep electrode identical are made up of transparency electrode and bus electrode, and its formation method is also identical with said method.
Then, form white bag White-Bag (312) on the addressing electrode, wrap White-Bag in vain and go up the dividing plate (313) that discharge cell is separated in formation.Such dividing plate forming process is as follows: expose after repeatedly printing with the slurry that comprises glass powder, behind the pattern with the method formation dividing plate that sandblasts, utilize the plastic device plasticity of ionic medium display floater of the present invention to form dividing plate.At this moment, the plasticity temperature of plasticity dividing plate slurry is more than 400 ℃ below 500 ℃, can carry out plasticity under than the low temperature of existing plasticity temperature.
The spraying fluorescer forms fluorescence coating (314) in the discharge cell that the dividing plate that is formed is like this distinguished.Such fluorescence coating forming method is as follows: after the fluorescer slurry that comprises glass powder sprays to discharge cell, carry out plastification to form fluorescence coating.At this moment, the plasticity temperature of plasticity fluorescer slurry also be than existing plasticity temperature low more than 400 ℃ below 500 ℃.
The front substrate that forms is like this combined (320) finish Plasmia indicating panel of the present invention (330) with the back substrate.
The same, utilize the plastic device of ionic medium display floater of the present invention to make Plasmia indicating panel, can reduce the plasticity temperature of insulating barrier, dividing plate, fluorescence coating, therefore the glass powder that comprises in insulating barrier, dividing plate, the fluorescence coating slurry and the material of front and back glass can be used low-cost Sodarlime glass, simultaneously can evenly heat test piece with this Production Gain that improves Plasmia indicating panel, therefore also can improve the uniformity of panel.
Can find that by foregoing invention technology of the present invention constitutes and can technological thought of the present invention or feature do not changed and be used with other concrete forms by the those skilled in the art under the present invention.But embodiment set forth above does not represent all aspects of the present invention, the present invention is not limited only to the foregoing description, scope of the present invention is decided by the concrete right claimed range that proposes later, and all changes that the meaning of accessory rights claimed range, scope and equivalent concepts thereof derive or the form of change all should belong to scope of the present invention.
Slurry commonly used is formed:
Macromolecule organic: acrylic acid series condensate or cellulose Cellouse are condensate,
Solvent: organic solvent, as aromatic solvent.
