Definitions
- the present invention relates to a composition that may be used for sealing applications in the manufacture of electronic displays.
- the composition includes organic vehicles that may be removed upon low temperature firing in air or inert atmospheres.
- a further embodiment of this invention is a sealing process comprising (a) depositing a bead or patterned layer of the composition of claim 1 on a first substrate, (b) volatilizing the solvent and/or organic vehicle, (c) bringing a second substrate into contact with the bead or patterned layer, and (d) firing the bead or patterned layer.
- the organic vehicle in the composition is thermally fugitive and/or pyrolyzes at low temperature. While pyrolysis usually involves the transformation of a material into other substances through the application of heat alone in the absence of oxidation, the organic vehicle as used herein is fugitive in air at a temperature of 430° C. or less. In particular embodiments where oxygen is excluded, such as an atmosphere of nitrogen or other inert atmosphere, the organic vehicle is also fugitive at a temperature of 430° C. or less.
- Glass frits typically contain finely ground inorganic materials mixed with fluxes, which are transformed into a glass or enamel upon heating. Suitable glass frits include those that contain materials such as PbO, B 2 O 3 , Al 2 O 3 , SiO 2 and ZnO, and may be obtained commercially from suppliers such as Viox, Asahi and DuPont.
- the median particle size (d50) of the glass frit is about 1 to about 100 microns ( ⁇ m), is preferably about 1 to about 50 microns, and is more preferably about 1 to about 25 microns.
- composition will contain a suitable low boiling solvent, representative examples of which include an ester alcohol, hexane, heptane, toluene, methylene chloride, ethyl acetate, butyl acetate, methyl ethyl ketone and xylenes.
- a suitable low boiling solvent representative examples of which include an ester alcohol, hexane, heptane, toluene, methylene chloride, ethyl acetate, butyl acetate, methyl ethyl ketone and xylenes.
- the components of the composition may be present therein in amounts, by total weight of the composition, as follows: organic vehicle—about 1 to about 20 parts by weight (pbw) or about 5 to about 15 pbw, glass frit—about 60 to about 100 pbw or about 65 to about 95 pbw, solvent—about 1 to about 40 pbw or about 10 to about 25 pbw, and (when present as an optional component) filler—about 1 to about 5 pbw or about 1.5 to about 3 pbw; where the pbw may, but need not, add to 100.
- organic vehicle about 1 to about 20 parts by weight (pbw) or about 5 to about 15 pbw
- glass frit about 60 to about 100 pbw or about 65 to about 95 pbw
- solvent about 1 to about 40 pbw or about 10 to about 25 pbw
- filler about 1 to about 5 pbw or about 1.5 to about 3 pbw; where the pbw may, but need not, add
- compositions can be used in bonding glass surfaces to each other for use, for example, in field emission devices or lighting devices. They provide highly reliable glass-to-glass seals, for example, in electronic display applications such as in flat panel displays, which contain electronic device elements such electron field emitters.
- front and back glass substrate plates that together make up the outer structure of the display are sealed together with a sealing composition.
- the enclosed cavity between the glass plates containing other elements of the display is evacuated to a low gaseous pressure.
- the front and back glass substrate plates are also the anode and cathode of the display.
- the sealing composition is applied near the outer edges of the anode and cathode glass substrate plates as a printed or extruded thick film paste deposit.
- the sealing composition may be applied on the anode or cathode substrate only, and then the two substrate plates are brought in contact. Incorporation of an organic vehicle in the composition is necessary to enable proper deposit of the composition as a thick film paste in the desired location.
- the substrate plates may be brought together before or after volatilization of the organic vehicle and/or solvent, and the firing of the sealing composition. Volatilization of the organic vehicle and/or solvent may be performed by evaporation at ambient temperature or by drying at a low temperature such as about 125° C. Fired compositions may be refired to accomplish sealing.
- low temperature elimination of the organic vehicle is particularly important in the case of field emission displays (FEDs) that comprise acicular emitting substances such as acicular carbon, e.g. single-wall or multi-wall carbon nanotubes (CNTs), as emitter elements.
- FEDs field emission displays
- acicular emitting substances such as acicular carbon, e.g. single-wall or multi-wall carbon nanotubes (CNTs)
- CNTs carbon nanotubes
- Other components of displays or other electronic devices can also be susceptible to degradation at elevated temperature, particularly in the presence of oxygen.
- a sealing composition that is processed at lower temperatures, and/or that requires no oxygen, for adequate removal of the organic vehicle offers a strong practical advantage in display manufacture.
- composition of this invention provide a high vacuum seal between plates of glass such that the resulting cavity between the plates can be pumped down to about 10 ⁇ 7 torr vacuum or lower.
- the composition, when fired in the manner described herein, will have a glossy surface. A composition that fires out with a matt surface appearance is less likely to provide acceptable sealing of the glass plates.
- Organic vehicles for use in the following examples are prepared as described below. These OVs are different mixtures of PAMS, butylated PAMS and polymethacrylate oligomers, primarily dimers and trimers, as shown in Table 1.

- firing occurs at a lower temperature (280° C. to 400° C.) to eliminate the bulk of the low firing organic vehicle.
- the low temperature firing may be carried out in air.
- the preferred mode is to carry out the firing in an inert atmosphere such as nitrogen to minimize oxidation of other components of the device being fabricated, when such components are an integral part of the glass plates which are being sealed together.
- firing occurs at a higher temperature (360° C. to 480° C.) in an inert atmosphere (such as nitrogen) to sinter the glass frit and create a hermetic seal between the glass substrates.

- the tolerance for low levels (1-1,000 ppm) of oxygen in this firing step is solely dependent on the sensitivity of the other components of the device to oxygen.
