| 20080266204 | Method, Device and System for Creating Images, Text and Information that are Visible Under Incident Light | 10-30-2008 |
| 20090262410 | Device For The Pixel-Integrated Return Of Fluid - An apparatus for the pixel-integrated return of fluid in the pixel of a fluidic display is characterized in that the fluid with which the desired information is to be displayed and/or the carrier fluid in which the fluid is optionally embedded can be returned in a particularly compact manner and in a manner which is invisible to an observer past the visible part of a pixel (image compartment) into a reservoir (reservoir compartment) through or out of the reservoir. The device comprises an image compartment, a reservoir compartment, a connecting duct and at least one return duct, whereby the at least one return duct is formed by the fact that the connecting duct has at least one area with an uninterruptedly enlarged cross section which transitions in a specified manner into the cross section of the original cross section. | 10-22-2009 |
| 20090316252 | Fluidic Multi Color Display - The apparatus claimed by the invention uses as the display medium colors in the form of colored fluids which are transported by means of transport in a system of compartments within a fluidic chain, whereby they are visible from the direction of an observer only through a single one these compartments (image compartment). Depending on the position of the individual colored fluids, a different color impression is received by the observer. The invention thereby teaches the presence of a fluidic chain in a subpixel and the combination of a plurality of these subpixels in a pixel. The display claimed by the invention consists of a plurality of pixels. With the use of eight colors in connection with an optically created color mixing effect, a color space can be displayed which is sufficient at least for the display of the information typically used on advertising signs. | 12-24-2009 |
| 20100108516 | USE OF A FLUID MIXTURE FOR ELECTROWETTING A DEVICE - The invention relates to the use of a fluid mixture for electrowetting in a device that is suitable for this. | 05-06-2010 |
| 20100165441 | LAYER COMPOSITION OF AN ELECTROWETTING SYSTEM - A layer composition of an electrowetting system with a first electrode layer, an insulator layer on the first electrode layer, and a fluid layer over the insulator layer, wherein the fluid layer comprises at least two immiscible fluids which, under the influence of an applied voltage, reversibly change their wetting behavior of a surface allocated to the insulator layer, wherein the insulator layer being at least in part built of a material with a permittivity of ε | 07-01-2010 |
| 20110063334 | Display Element and a Method for Driving a Display Element - Display element with at least one color-generating cell of the first type which has an emissive light source, and with at least one color-generating cell of the second type which has a reflective and/or transmissive and/or transflective light source, whereby each cell of the second type can be driven so that it makes visible one of the chromatic colors red, green, blue, magenta, cyan and yellow and the achromatic colors white and black, to compensate at least partly for the absence of the color impression created by at least one color-generating cell of the first type on account of the ambient light of the display element. | 03-17-2011 |
| 20110083963 | Liquid Transport Using Electrowetting Supported by Effective Arrangement of Electrodes - An arrangement of electrodes is provided in which there is a plurality of electrodes located in two planes and offset from one another in the direction of movement, and which within each plane are arranged in at least two electrically interconnected and alternating groups. A method is also provided for the movement or transport of drops of liquid utilizing the electrowetting effect and utilizing the above arrangement. | 04-14-2011 |
| 20110216391 | Security Element - The invention relates to a security element including at least one display element for non-resettable visible display of information, wherein said display element comprises a first and a second volume which are fluidically connected via at least one duct, and only one electrically controllable electrode which is associated to one of said volumes and is configured, when charged with an electric voltage, to vary the surface tension of a liquid which is present in said associated volume, wherein said liquid comprises at least an electrically conducting and/or polar and a non-polar fraction, and at least said electrically conducting fraction being completely and in a stable manner provided in that of both volumes which is not associated with an electrode and wherein said electrically conducting and/or polar fraction may be moved irreversibly and at least partly due to a single charging of the electrode into the volume which is associated with an electrode. | 09-08-2011 |
