Abstract: Modulator devices are selectably adjustable between at least two states, wherein the transmission and/or reflection of particular wavelengths of light are modified. Certain modulator devices are substantially uniformly adjustable over a wide range of wavelengths, including visible and infrared wavelengths. Other modulator devices are adjustable over visible wavelengths without significantly affecting infrared wavelengths. In addition, the modulator devices may be used in conjunction with fixed thin film reflective structures.

Abstract: MEMS varactors capable of handling large signals and/or achieving a high capacitance tuning range are described. In an exemplary design, a MEMS varactor includes (i) a first bottom plate electrically coupled to a first terminal receiving an input signal, (ii) a second bottom plate electrically coupled to a second terminal receiving a DC voltage, and (iii) a top plate formed over the first and second bottom plates and electrically coupled to a third terminal. The DC voltage causes the top plate to mechanically move and vary the capacitance observed by the input signal. In another exemplary design, a MEMS varactor includes first, second and third plates formed on over one another and electrically coupled to first, second and third terminals, respectively. First and second DC voltages may be applied to the first and third terminals, respectively. An input signal may be passed between the first and second terminals.

Abstract: Some implementations of the invention provide hidden static images. Some such images can only be perceived when viewed from an angle to the normal to a surface. Such images may appear as a solid color when viewed along an axis perpendicular to a surface, but may reveal a hidden image when viewed from an angle relative to that axis. The hidden image may be defined according to interfaces between areas that pass substantially the same wavelength when viewed along the axis, but which pass noticeably different wavelengths when viewed from an angle relative to that axis. The hidden images may or may not be discernable to a human observer. The hidden image may comprise a code that is not readable by an optical scanner positioned to read along an axis normal to a surface, but that is readable by an optical scanner positioned to read along another axis.

Abstract: An apparatus and method for reducing perceived color shift as a function of viewing angle is disclosed. One embodiment is a display device that includes a color light modulator and a color filter. The filter is configured to filter wavelengths of light that would be perceived as color shifted light when reflected by the modulator at an off-axis viewing angle. Another embodiment includes a color light modulator and a color light source configured to provide light having a spectral content that lacks the wavelengths that would be perceived as color shifted light by a view of the display at an off-axis viewing angle. Another embodiment are methods of making such display devices.
