20120038861 | Electronic Display Comprising An Adjustable Color Filter - A color display, and an electronic apparatus comprising the color display, are described herein. The display comprises an illumination unit overlaid with a color filter arranged with a plurality of color filter elements, wherein respective transmissions of the color filter elements are adjustable to allow either transmission for a selected wavelength in said range of wavelengths, or transmission for a number of wavelengths from said range of wavelengths. Such adjustable transmission may be implemented using actuatable fluids which may be controlled by means of electrowetting. | 02-16-2012 |
20120086691 | ELECTROFLUIDIC CHROMATOPHORE (EFC) DISPLAY APPARATUS - A display apparatus is described that includes a plurality of electrofluidic chromatophore (EFC) pixel cells. Each pixel cell comprises a fluid holder for holding a polar fluid and a non-polar fluid having differing display properties, the fluid holder comprising a reservoir with a geometry having a small visible area projected in the direction of a viewer onto the polar fluid, and a channel with a geometry having a large visible area projected in the direction of a viewer onto the polar fluid. The channel is connected to the reservoir so as to enable free movement of the polar fluid and non-polar fluid between the channel and the reservoir. At least part of a surface of the channel comprises a wetting property responsive to a supply voltage over the pixel cell and defining (i) a stable region wherein the supply voltage stabilizes polar fluid in the channel; (ii) a fill region that controls filling of polar fluid in the channel and (iii) a retract region that controls retracting of polar fluid in the channel. At least two pixel cell terminals are configured to supply the supply voltage to at least part of the surface of the channel comprising the wetting property for supply voltage controlled channel movement of polar fluid. The display further comprises a driver operative to provide controlled column voltages and any of a predefined row select or non-select voltage. A circuit board comprises a row electrode and a column electrode each directly connecting the driver to the pixel cell terminals for supplying the supply voltage to the pixel cell terminals as a voltage difference between the row and column electrodes in a passive matrix configuration. | 04-12-2012 |
20120092319 | Common Driving Of Displays - A display driving arrangement is described wherein, during a scan line driving phase, a column driver is controlled to provide a plurality of driving column voltages to the source terminals and the row driver is controlled to provide scanning row selection voltages to the gate terminals for sequentially updating the each pixel having an initial pixel state, voltages with said plurality of driving column voltages to attain, for each initial pixel state, an initial common pixel state. During a common driving phase the column driver is controlled to provide a uniform column voltage to the source terminals to update the plurality of pixel voltages with a uniform column voltage. In addition, the row driver is controlled to provide row select voltages with a gate swing that is lower during the common driving phase than during the row driving phase so as to drive the pixels from a respective the initial common state to a respective final common state. The pixel states may differ from each other at least during a part of the common driving phase or even during the entire common driving phase, so that initial and final common states and intermediate states may differ from pixel to pixel. | 04-19-2012 |

20130113761 | ELECTRONIC DEVICE WITH A TOUCH SENSITIVE PANEL, METHOD FOR OPERATING THE ELECTRONIC DEVICE, AND DISPLAY SYSTEM - An electronic device having a touch sensitive panel has an opened and a closed state, and comprises a sensor circuit, a touch simulation facility and a comparator. The sensor circuit is for generating a touch signal indicative for a position where a touch of the touch sensitive panel is detected. The touch simulation facility is for evoking a touch signal at a position of the touch sensitive panel, and comprises a touch simulation element which in the closed state of the electronic device is arranged opposite the touch sensitive panel. The comparator is for comparing the touch signal with a reference value corresponding to the touch simulation element and for generating a correction signal for adjusting a setting of the sensor circuit for compensation of a difference detected between the position where the touch signal is evoked and the position indicated by the touch signal. | 05-09-2013 |
