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.

An absorbing layer of a low-E coating is designed to cause the coating to have a more neutral and/or green color at normal and/or certain off-axis viewing angles. In certain example embodiments, the metallic or substantially metallic absorbing layer (e.g., NiCr) is from about 20-30 angstroms (Å) thick; this thickness has been found to unexpectedly provide less red and more neutral coloration for the coated article at certain off-axis viewing angles (e.g., at a 45 degree off-axis viewing angle). In certain example embodiments, the absorbing layer is provided between first and second nitride layers in order to reduce or prevent oxidation thereof during heat treatment thereby permitting predictable coloration to be achieved following the heat treatment. Coated articles according to certain example embodiments of this invention may be used in the context of insulating glass (IG) window units, vehicle windows, other types of windows, or in any other suitable application.
