Abstract: A solar control member for determining solar control for a window includes an optically massive layer between a gray metal layer and a titanium nitride layer. The optically massive layer has sufficient thickness to retard or prevent constructive and destructive interference of reflected light. The optically massive layer may be an adhesive, but also may be one or more polymeric substrates. The gray metal layer is preferably nickel chromium, but other gray metal materials provide superior results as compared to the prior art. Also in the preferred embodiment, the titanium nitride layer is closer to the window (e.g., glass) than the gray metal layer.

Abstract: Conductive micro traces (64) are formed on a coated or uncoated substrate (28) in order to achieve a combination of target optical properties and target electrical capabilities. For the coated substrate, the coating (100) may be formed before or after the conductive micro traces. The coating may be designed for providing IR filtering or reductions in reflected light and color shift, while the conductive micro traces may be used for EMI shielding or to provide current-carrying capability, such as when used as heaters. In another embodiment, the conductive micro traces are formed on an uncoated flexible transparent substrate and have a width of less than 25 microns, such that the conductive micro traces are capable of achieving their intended purpose while maintaining a high visible light transmissivity. The conductive micro traces may be formed using various approaches, such as the use of electroplating techniques or the use of inkjet printing techniques.

Abstract: A solar control member for determining solar control for a window includes an optically massive layer between an optically functional layer stack and a titanium nitride layer. The optically massive layer has sufficient thickness to retard or prevent constructive and destructive interference of reflected light. The optically massive layer may be an adhesive, but also may be one or more polymeric substrates. The layer stack may be a Fabry-Perot interference filter. Also in the preferred embodiment, the titanium nitride layer is closer to the window (e.g., glass) than the layer stack.
