| 20080309612 | Spatially Masked Update for Electronic Paper Displays - Electronic Paper Displays can suffer from “ghosting” or previous images remaining partially visible after the display has updated to show a new image. A pseudo-random noise intermediate image is used to make the ghosting less visible to human observers. Further, other intermediate images can be used to convey visible information or to convey secret information, e.g. a watermark. A control signal for driving the bi-stable display from the current optical state to an intermediate state, then to a final optical state is also determined. In some embodiments, the intermediate state for each pixel is determined in a pseudo-random manner. The pseudo-random noise values are applied to the bi-stable display to remove noise and other artifacts from the end resulting images. The determined control signal is applied to the bi-stable display to drive the bi-stable to the intermediate state, then to the final optical state. | 12-18-2008 |

| 20100127965 | MERCHANDISE DISPLAY DEVICE WITH COLOR-CHANGING SURFACE AND METHOD OF FABRICATING THE SAME - A merchandise display device comprising: an electro-optic display member having an effective display area capable of displaying colors or images; a first means for displaying merchandise on or near said effective display area; a second means for providing physical support to said electro-optic display member; and a controller device for driving said electro-optic display member. The merchandise display device is capable of showing dynamic colors, images, or both on its surface, and an article of merchandise may be displayed on or near said surface, with said dynamic colors, images, or both being the display background. | 05-27-2010 |
| 20120139824 | ELECTROCHROMIC DISPLAY ELEMENT, DISPLAY DEVICE AND INFORMATION APPARATUS - A disclosed electrochromic display element includes a display substrate, a counter substrate facing the display substrate, display electrodes arranged between the display substrate and the counter substrate, electrochromic layers formed on the respective display electrodes, a plurality of drive elements arranged on the counter substrate at predetermined intervals, a plurality of pixel electrodes arranged on the drive elements, a charge retention layer formed over the pixel electrodes as a continuous layer, the charge retention layer being formed of a mixed film including a polymer and one of electric conductive microparticles and semiconductor microparticles, and an electrolyte layer sandwitched between the display substrate and the charge retention layer. | 06-07-2012 |
| 20120139825 | ELECTROCHROMIC DISPLAY DEVICE - An electrochromic display device includes a display substrate, a counter substrate facing the display substrate, counter electrodes arranged on the counter substrate, an electrolyte layer arranged between the display substrate and the counter electrodes, display electrodes separately arranged from one another between the display substrate and the counter electrodes, electrochromic layers to develop or reduce a color by redox reactions, the electrochromic layers being formed on the respective display electrodes arranged such that the electrochromic layers face the set of the counter electrodes, a voltage applying unit to select one of the display electrodes to connect the selected display electrode and the counter electrodes to apply a voltage between the connected display electrode and counter electrodes, a disconnecting unit to disconnect the unselected display electrodes from the counter electrodes, and an interelectrode connecting unit to connect the display electrodes. | 06-07-2012 |
| 20130215004 | DATAMATRIX CODE ARRANGEMENT AND METHOD FOR MANUFACTURING THE SAME - A data matrix code arrangement, and a method for making the same are disclosed. The data matrix code arrangement includes a fix data matrix code including a static pattern forming a first readable Data Matrix code, and an electrochemically switchable organic electrochromic display comprising pixel element including a controller arranged for enabling an application of a predetermined potential difference between an electrochromic layer and a counter electrode layer of the pixel element. The application of a potential difference initiates and maintains a colour switch of the predetermined ones of the pixel elements. The fix Data Matrix code and the display are aligned such that the static pattern of the first Data Matrix code and the predetermined ones of the pixel elements, when switched, forms a second readable Data Matrix code, which is different from the first readable Data Matrix code. | 08-22-2013 |
