Abstract: The optical performance is enhanced of display systems that use field sequential color and pulse width modulation to generate color and color gray scale values. Such enhancement may be achieved by various data encoding methods disclosed herein that may include temporal redistribution of bit values to mitigate color motional artifacts associated with field sequential color-based display systems, selective combination of intensity modulation, pulse width modulation, and/or the noncontiguous sequencing of primary colors. There is further an intelligent real-time dynamic manipulation of gray scale values in portions of an image that are computationally determined to be images of objects moving against a global background, so as to temporally front load or concentrate the bits comprising such moving objects and thereby further mitigate said motional artifacts using both actual and virtual aggregate pulse truncation across all primary colors being modulated.

Abstract: Mutual capacitance touch sensor circuits are used in manufacturing displays, including touch screen displays, such as LED, LCD, plasma, 3D, and other displays used in computing as well as stationary and portable electronic devices. A flexographic printing process may be used, for example, in a roll to roll handling system to print geometric patterns on a substrate, for example, a flexible dielectric substrate. These patterns may then be coated with a conductive material by, for example, an electroless plating process.

The method may also include electrolessly plating the patterned substrate.

Abstract: The attenuation of light per unit length in a waveguide as a result of active pixels (i.e., open pixels) may be corrected or mitigated by injecting apodized light into the waveguide. A light injection system and method is provided to enhance the luminous uniformity of the active pixels in a waveguide-based display.

The first light source, or the second light source, or both, comprises an apodized light source.

Abstract: Embodiments of a display comprising pixels formed from suitably tethered deformable membrane-based MEMS subsystems are provided that include the means to dynamically alter the in-plane tension, and thus the effective spring constant, of the deformable membrane being ponderomotively propelled between active and inactive optical states, said dynamic alteration being effected by exploiting transverse piezoelectric properties of the deformable membranes. Manipulating the spring constant can reduce the actuation force required to turn pixels on, thus significantly reducing the operational voltages for the display composed of an array of such subsystems. Since display power rises with the square of the pixel drive voltage, such architectures give rise to more power efficient display systems.

The light extraction features in a first set of the regions are arranged with their long dimension orthogonal to the long dimension of the light extraction features in a second set of the regions.

Abstract: The application of optical microstructures improve the quality of light available to the viewer of an optical display system, or any display which works on the concept of moving one surface into direct contact or close proximity of a light guide to extract light through frustrated total internal reflection. Certain ones of the microstructures can act to assist in overcoming stiction between the surface and the light guide.

Abstract: The present invention provides an apparatus that includes a waveguide and one or more pixels deployed adjacent the top surface of the waveguide which contains TIR light therein. Each pixel includes a deformable active layer having a first conductor and a driver electronics layer having a second conductor. The driver electronics layer is deployed in spaced-apart relation to the active layer and opposite the waveguide. In a quiescent state of a pixel, the active layer is in contact or near contact with the top surface of the waveguide so as to optically couple light out via FTIR (i.e., pixel's ON state). To actuate the pixel, the electronics layer is configured to selectively apply an electrical potential difference to the second conductor thereby causing the active layer to move away from the top surface so as to prevent the optical coupling of light out of the waveguide (i.e., pixel's OFF state).
