A method of finding defects in sealing material formed as a frame line on a glass plate includes irradiating the frame line of sealing material. A temperature of the irradiated sealing material is measured and a change of the temperature caused by a nonuniformity in sealing material is detected. Another aspect features a method of hermetically sealing a thin film device between glass plates. Sealing material is dispensed on a cover glass plate in the form of a frame line cell. The sealing material is pre-sintered onto the cover glass plate and cooled. A laser beam is moved around the frame line on the sealing material. A temperature of the sealing material contacted with the laser beam is measured. A change in the temperature (ΔT) caused by a nonuniformity in the sealing material is measured. Further aspects include a feedback process, infrared imaging and use of delta temperature data to increase sensitivity of temperature measurement data.

The carbon electrode comprises an electrically conductive porous carbon support and a carbon cover layer comprising carbon particles in contact with the electrically conductive porous carbon support. A carbonizable material is within the electrically conductive porous carbon support and provides a bond to the carbon particles at the interface of the electrically conductive porous carbon support and the carbon cover layer. The electrically conductive porous support in some embodiments is a layered structure, where one of the layers is a carbonizable paste layer having electrically conductive particles mixed therein.

Systems and methods for measuring the stress profile of ion-exchanged glass are disclosed, based on the TM and TE guided mode spectra of the optical waveguide formed in the ion-exchanged glass. The method includes digitally defining from the TM and TE guided mode spectra positions of intensity extrema, and calculating respective TM and TE effective refractive indices from these positions. The method also includes calculating TM and TE refractive index profiles nTM(z) and nTE(z) using either an inverse WKB calculation or a fitting process that employs assumed functions for nTM(z) and nTE(z). The method also includes calculating the stress profile S(z)=[nTM(z)−nTE(z)]/SOC, where SOC is a stress optic coefficient for the glass substrate. Systems for performing the method are also disclosed.
摘要:
Packages for elements, e.g., OLEDs, that are temperature sensitive are provided. The packages have a first glass substrate (12), a second glass substrate (16), and a wall (14) that separates the first and second substrates (12,16) and hermetically seals at least one temperature sensitive element (18,28,36) between the substrates (12,16). The wall (14) comprises a sintered frit and at least a portion of the wall is laser sealed to the second substrate (16) by melting a glass component of the sintered frit. The minimum width (40) of the laser-sealed portion of the wall (14) at any location along the wall (14) is greater than or equal to 2 millimeters so as to provide greater hermeticity and strength to the package. The laser sealing is performed without substantially degrading the temperature sensitive element(s) (18,28,36) housed in the package.
