20130033476 | DISPLAY APPARATUS - A device, an electrode configuration and a sequence for activating those electrodes for the purpose of switching device states quickly with minimum flicker during bi-stable image reset. The disclosure addresses the constraints of electrofluidic technology: 1) the polar fluid can be attracted to a position with voltage, but it cannot be repelled, and 2) because the polar fluid translates, changing its area against an electrode and thereby changing the capacitance, the time to discharge the capacitor formed by area contact with a polar fluid is significantly smaller than the time to charge a capacitor, which requires translation of the fluid. Setting the grayscale is based on discharging, not charging, when possible. In addition, the use of pixel-level partial reset states reduces the appearance of flicker further by minimizing the change in pixel state during data write/update. | 02-07-2013 |
20130128336 | SPECTRUM-MODULATED SMART WINDOWS - Methods, systems, devices and/or apparatuses are provided that selectively reflect the infrared spectrum independent of other regions of the solar spectrum in order to actively manage solar heat gain across surfaces such as windows, skylights, roofs, siding and the like. | 05-23-2013 |
20130335805 | CONTROLLED DIFFUSE SCATTERING FOR DISPLAYS - A display device comprising a pixel, where the pixel includes: (a) a polar fluid that is at least one of colored and black, (b) a non-polar fluid that is at least one of transparent and translucent, (c) a first substrate, (d) a second substrate arranged relative to the first substrate to define a channel occupied by the polar fluid and the non-polar fluid, wherein at least one of the polar fluid and the non-polar fluid is visible through at least one of the first substrate and the second substrate, (e) a reflector having a plurality of features, comprising at least one of concavities and projections, that alter an angle of reflected light from a specular reflection to provide the appearance of at least one of a diffuse reflection and a non-metallic reflection, where the reflector includes a hydrophobic coating causing the polar fluid that is at least one of colored and black to be non-wetting to the hydrophobic coating in the presence of the non-polar fluid, the display device also including a plurality of electrodes configured to cause repositioning of the polar fluid in the channel to displace at least a first portion of the non-polar fluid and a voltage source, where repositioning of the polar fluid occurs as a unified volume to retard reduced light reflection from the reflector in a portion of the channel where the polar fluid has been repositioned. | 12-19-2013 |
