20080303780 | DRIVING METHODS AND CIRCUIT FOR BI-STABLE DISPLAYS - The disclosure is directed toward driving methods and a driving circuit which are particularly suitable for bi-stable displays. In certain embodiments, methods provide the fastest and most pleasing appearance to the desired image while maintaining the optimal image quality over the life expectancy of an electrophoretic display device. | 12-11-2008 |
20090096745 | APPROACH TO ADJUST DRIVING WAVEFORMS FOR A DISPLAY DEVICE - The present invention is directed to methods for adjusting or selecting driving waveforms in order to achieve a consistent optical performance of a display device. When a method of the present invention is applied, even if there are changes in the display medium due to temperature variation, photo-exposure or aging, the optical performance can be maintained at a desired level. | 04-16-2009 |
20100194789 | PARTIAL IMAGE UPDATE FOR ELECTROPHORETIC DISPLAYS - The present invention is directed to methods for partial image updates. Such methods provide the display controller the ability to update selected areas of an image that require updating and leave other areas unchanged. The methods also allow for multiple waveforms to be used for specific regions, giving the display the capability of updating each region with its own waveform. | 08-05-2010 |
20100196651 | MOLD MANUFACTURING OF AN OBJECT COMPRISING A FUNCTIONAL ELEMENT, TRANSFERING PROCESS AND OBJECT - This invention relates to an object having a functional element embedded in its top surface and processes for its manufacturing. The object is in general formed by molding, stamping, lamination or a combination thereof. The functional element is includes any electrical or mechanical elements that are capable of performing a function. | 08-05-2010 |
20100271407 | REFLECTIVE DISPLAY DEVICES WITH LUMINANCE ENHANCEMENT FILM - The present invention is directed to reflective display devices with a luminance enhancement structure on its viewing side and at least an auxiliary layer and/or edge sealing. The structure increases the overall reflectance by reducing the total internal reflection, and as a result, the brightness of a display device is increased. | 10-28-2010 |
20110305271 | High-Speed Signaling Systems With Adaptable Pre-Emphasis and Equalization - A signaling system includes a pre-emphasizing transmitter and an equalizing receiver coupled to one another via a high-speed signal path. The receiver measures the quality of data conveyed from the transmitter. A controller uses this information and other information to adaptively establish appropriate transmit pre-emphasis and receive equalization settings, e.g. to select the lowest power setting for which the signaling system provides some minimum communication bandwidth without exceeding a desired bit-error rate. | 12-15-2011 |

20140161166 | Margin Test Methods and Circuits - Described are methods and circuits for margin testing digital receivers. These methods and circuits prevent margins from collapsing in response to erroneously received data, and can thus be used in receivers that employ historical data to reduce intersymbol interference (ISI). Some embodiments detect receive errors for input data streams of unknown patterns, and can thus be used for in-system margin testing. Such systems can be adapted to dynamically alter system parameters during device operation to maintain adequate margins despite fluctuations in the system noise environment due to e.g. temperature and supply-voltage changes. Also described are methods of plotting and interpreting filtered and unfiltered error data generated by the disclosed methods and circuits. Some embodiments filter error data to facilitate pattern-specific margin testing. | 06-12-2014 |
20140300651 | DRIVING BISTABLE DISPLAYS - The invention relates to waveforms, circuits and methods for driving bistable displays. The invention is directed to a method, comprising in combination: applying, across a bistable display device, a shaking signal comprising a plurality of positive and negative pulses each driven for a first time to disperse partially packed particles; applying, across the device, one or more first driving signals to first pixels of the device for second times that are sufficient to drive the first pixels to one or more reference states; and concurrently with the first driving signals, applying, across the device, one or more second driving signals to second pixels of the device for third times that are shorter than necessary to drive the second pixels to any of the one or more reference states. | 10-09-2014 |
