Abstract: The present invention discloses a display panel substrate assembly and an apparatus and method for forming a display panel substrate assembly, wherein the substrate assembly includes a first substrate and a second substrate. At least one of the first substrate and the second substrate is optically clear. The method includes the steps of screen printing a non-sag adhesive composition onto a surface of the first substrate, bringing the non-sag adhesive composition into contact with a surface of the second substrate in an environment having a pressure of less than or equal to about 5000 pascals, and curing the non-sag adhesive composition to yield an adhesive layer. The non-sag adhesive composition is of a type which is optically clear after curing.

Abstract: A display panel assembly is made by optically bonding a display panel and a substantially transparent substrate. Optical bonding is carried out by forming an optical bonding layer having regions of different physical properties.

Abstract: Multi-layer articles capable of forming color images are provided. The articles include a multi-layer construction with at least two layers in which at least one of the layers includes a thermally activatable composition. The thermally activatable composition includes a non-linear light to heat converter composition and a color forming compound. Upon activation with a light source an image forms.

Abstract: An optically clear adhesive layer includes a liquid optically clear adhesive having a viscosity of less than about 20 Pa·s at a shear rate of 1 sec?1 and a thixotrope. The optically clear adhesive layer has a haze of about 2% or less, a viscosity of between about 2 and about 30 Pa·s at a shear rate of 10 sec?1, a displacement creep of about 0.2 radians or less when a stress of 10 Pa is applied for about 2 minutes and a recovery time of about 60 seconds or less to reach a delta of 35 degrees after a torque of about 100 microN·m is applied for about 60 seconds at a frequency of 1 Hz and immediately followed by a torque of 80 microN·m at a frequency of 1 Hz. The adhesive layer can be used in an optical assembly to bond a display panel to a substantially transparent substrate. The adhesive layer provides a cleavage strength between glass substrates of about 15 N/mm or less such that the optical assembly can be disassembled with little or no damage to the display panel or the substrate.

Abstract: A recordable data storage disc comprises a substrate having a spirally or concentrically shaped groove pattern. A groove depth of the groove pattern is greater than 90 nanometers, and a track pitch provided by the groove pattern is less than 500 nanometers. The data storage disc further comprises a write-once recording layer formed on the groove pattern, and a reflector layer formed on the recording layer opposite the substrate. The groove depth of greater than 90 nanometers allows a thicker coating of dye to be used for the recording layer compared to other recordable data storage discs with a groove pattern with a groove depth of 90 nanometers or less. The thicker coating of dye allows a lower write power, better modulation when reading a data signal from the disc. The groove depth of greater than 90 nanometers may also allow for more precise push-pull tracking.
