Abstract:
PROBLEM TO BE SOLVED: To hermetically seal an OLED display and simultaneously prevent the formation of Newton rings. SOLUTION: A top emission, organic light emitting diode display comprises an organic light emitting diode (OLED) 12, a first substrate 20 having an inner surface, and a second substrate 22 having an inner surface. The OLED 12 is sandwiched between the first substrate 20 and the second substrate 22. At least one of the first substrate 20 and the second substrate 22 includes a pocket 44 formed in the inner surface thereof having such a depth that a distance between the inner surface of the first substrate 20, and the inner surface of the second substrate 22 is sufficient to reduce or eliminate the formation of optical distortions such as Newton rings in the display 10. The display comprises a frit 32 located between the first and second substrates 20, 22 having a thickness such that the distance between the inner surfaces of the first and second substrates 20, 22 is great enough to prevent the formation of Newton rings.

PROBLEM TO BE SOLVED: To provide an airtight seal which has an improved processing speed and durability by dint of mechanical strength of a polymer adhesive seal as well as inertness of a frit seal. SOLUTION: A glass package is provided with a first substrate, a second substrate, frit which combines the first substrate with the second substrate, and a polymer adhesive which further combines the first substrate with the second substrate. At least a part of the first substrate is positioned and lapped on at least a part of the second substrate. The frit is composed of a glass part containing a basic component containing SiO 2 of by about 5 to about 75 mol%, B 2 O 3 by about 10 to about 40 mol% and Al 2 O 3 by 0 to about 20 mol%, and an absorbing component of at least one kind containing either (a) CuO by 0 to about 25 mol% or (b) Fe 2 O 3 by more than 0 to about 10 mol%, V 2 O 5 by more than 0 to about 10 mol%, and TiO 2 by 0 to about 5 mol%.

Abstract:
A hermetically sealed glass package and method for manufacturing the hermetically sealed glass package are described herein using an OLED display as an example. In one embodiment, the hermetically sealed glass package is manufactured by providing a first substrate plate and a second substrate plate. The second substrate contains at least one transition metal such as iron, copper, vanadium, manganese, cobalt, nickel, chromium, and/or neodymiu m. A sensitive thin-film device that needs protection is deposited onto the fir st substrate plate. A laser is then used to heat the doped second substrate pla te in a manner that causes a portion of it to swell and form a hermetic seal th at connects the first substrate plate to the second substrate plate and also protects the thin film device. The second substrate plate is doped with at least one transition metal such that when the laser interacts with it there is an absorption of light from the laser in the second substrate plate, which leads to the formation of the hermetic seal while avoiding thermal damage to the thin-film device. Another embodiment of the hermetically sealed glass package and a method for manufacturing that hermetically sealed glass packag e are also described herein.
Abstract:
A method for activating carbon via alkali activation processes includes the introduction of water vapor during the activation phase to control the formation of highly reactive by-products. The method includes heating the mixture of a carbon-containing first material and a alkali-containing second material, introducing water vapor at a first threshold temperature and stopping water vapor introduction at a second threshold temperature. The activated carbon material is suitable for carbon-based electrodes and for use in high energy density devices.

Abstract:
A separator such as for an electrochemical double layer capacitor includes acicular inorganic particles that are dried to form a porous membrane. Example inorganic particles are calcium silicate particles. A deposition method implementing slurry that includes the acicular inorganic particles and a dispersing medium along with a binder material can be used to form the separator layer directly on electrode materials.
