InactiveUS20100328248A1Improve electrical performanceImprove optical qualityInput/output processes for data processingVisibilityElectricity
An improved touch screen has enhanced optical performance and aesthetic quality. The electrodes on the touch screen employ additional fine traces of conductive material to reduce the overall electrode trace resistance to increase electrical performance without sacrificing optical quality. The additional fine traces of conductive material may be placed on the top of the ITO traces or in channels inside the boundaries of the ITO traces. The additional traces preferably run the length of the ITO traces to reduce the resistance in the longer dimension. Further, the additional traces are very small in width such that in the aggregate they cover only a small portion of the ITO electrode trace in lateral dimension to reduce the visibility of the additional traces. The conductive material may also be formed as a plurality of geometric shapes substantially forming a line in the longer dimension of the transparent conductive traces to reduce the visibility of the conductive material.

Described herein are the materials, mechanisms and procedures for optimizing various performance parameters of HPDLC optical devices in order to meet differing performance requirements. These optimization tailoring techniques include control and independent optimization of switchable HPDLC optical devices to meet the demanding requirements of anticipated applications for, inter alia, the telecommunications and display industries. These techniques include optimization of diffraction efficiency, i.e., index modulation, polarization dependence control, haze, cosmetic quality, control of response and relaxation time, voltage driving for on and off switching, and material uniformity. This control and independent optimization tailors properties of switchable HPDLC optical devices according to the specific requirements of the application of the switchable HPDLC optical device. The invention disclosed herein retains the desirable attributes of the multi-functional acrylate system for forming HPDLC optical devices, but adds new materials to the acrylate system and / or new process control to the recording to optimize performance parameters as may be needed for specific applications. This results in high optical quality switchable holograms with good diffraction efficiency and low, stable switching voltage.

Process of changing the refractive index of a composite containing a polymer and a compound having large dipole moment and polarizability and applications thereof
InactiveUS6090332AReduce the valuePoor resolutionRecord information storageDigital storageThermoplasticBiological imaging
Fused ring bridge, ring locked dyes that form thermally stable photorfractive compositions. The fused ring bridge structures are pi -conjugated bonds in benzene-, naphthalene- or anthracene-derived fused ring systems that connect donor and acceptor groups. The donor and acceptor groups contribute to a high molecular dipole moment and linear polarizability anisotropy. The polarization characteristics of the dye molecules are stabilized since the bonds in the fused ring bridge are not susceptible to rotation, reducing the opportunity for photoisomerization. The dyes are compatible with polymeric compositions, including thermoplastics. The dyes are electrically neutral but have charge transport, electronic and orientational properties such that upon illumination of a composition containing the dye, the dye facilitates refractive index modulation and a photorefractive effect that can be utilized advantageously in numerous applications such as in optical quality devices and biological imaging.

Thick porous anodic alumina films and nanowire arrays grown on a solid substrate
InactiveUS7267859B1Promote growthMore tractableMaterial nanotechnologyAnodisationSingle stageElectrochemistry
The presently disclosed invention provides for the fabrication of porous anodic alumina (PAA) films on a wide variety of substrates. The substrate comprises a wafer layer and may further include an adhesion layer deposited on the wafer layer. An anodic alumina template is formed on the substrate. When a rigid substrate such as Si is used, the resulting anodic alumina film is more tractable, easily grown on extensive areas in a uniform manner, and manipulated without danger of cracking. The substrate can be manipulated to obtain free-standing alumina templates of high optical quality and substantially flat surfaces PAA films can also be grown this way on patterned and non-planar surfaces. Furthermore, under certain conditions the resulting PAA is missing the barrier layer (partially or completely) and the bottom of the pores can be readily accessed electrically. The resultant film can be used as a template for forming an array of nanowires wherein the nanowires are deposited electrochemically into the pores of the template. By patterning the electrically conducting adhesion layer, pores in different areas of the template can be addressed independently, and can be filled electrochemically by different materials. Single-stage and multi-stage nanowire-based thermoelectric devices, consisting of both n-type and p-type nanowires, can be assembled on a silicon substrate by this method.
