To accomplish this, a baseline full scale output FS_targ_cal can be measured at during pre-delivery calibration for each pixel using a test fixture capable of applying a no-touch to full-touch condition given a nominal Vstim.

However, if two candidate patches for merging have a total number of pixels below a certain threshold, these two patches may not be merged under the assumption that the patches might have been caused by different fingertips. Conversely, if two candidate patches for merging have a total number of pixels above a certain threshold, these two patches can be merged under the assumption that the patches were caused by a single thumb or palm. | 2008-12-18 |

Small lateral motions indicative of a sloppy tap can be suppressed, while fast finger motions indicative of a quick, long cursor movement can immediately pass through the filter without being suppressed by a significant amount. A motion pass-through suppression factor can be applied subtractively to motion in particular direction as a function of Zinst and Tinst, wherein Zinst can represent a suppression value given as a finger speed for a particular percentage change in touch instability per frame, and Tinst can represent a suppression value given as finger speed for a particular tpress. | 2008-12-18 |

These panels can be designed, for example, by placing more stimulus and/or data lines in different portions of the panel, thus ensuring different densities of pixels in the different portions. Optionally, these embodiments can also include the dynamic granularity changing features noted above. | 2008-12-18 |

For a finger rotation gesture, the scaling speed can be computed as a cross product of the velocity vectors of the rotating fingers. The translation speed of a gesture can be computed as the average of the velocity vectors of any fingers involved in the gesture. The amount of gesture scaling speed and translation speed needed to trigger the recognition of a combined gesture with translation can be a predetermined ratio. | 2008-12-18 |

The present invention also includes a method for displaying video on an electronic paper display. | 2008-12-18 |
20080309649 | CURRENT DRIVE CIRCUIT AND DISPLAY APPARATUS - A current drive circuit supplies a driving current to a pixel portion included in a current-driven display panel. A driving current generator includes an output terminal for supplying the driving current. A protective transistor has a drain connected to the pixel portion, a source connected to the output terminal, and a gate to which a first bias voltage is supplied. The first bias voltage has a voltage level lower than or equal to a voltage level obtained by adding the threshold voltage of the protective transistor to the breakdown voltage of the driving current generator. | 2008-12-18 |
20080309650 | DISPLAY APPARATUS AND METHOD OF MANUFACTURING THE SAME - A display apparatus has a driving panel including a circuit part, a coating layer, and a display part, provided sequentially over a driving substrate. The driving panel includes: an adhesion region which includes the circuit part, the coating layer and the display part and to which a seal panel is adhered through an adhesive layer therebetween; and a terminal region protruding from the seal panel and the adhesive layer. A plurality of metallic wires electrically connected to the circuit part in the adhesion region are extended into the terminal region, and the coating layer is provided in the adhesion region with at least one separated region between the plurality of metallic wires. The separated region of the coating layer is so formed that an end edge thereof lies beyond the adhesion region to reach the terminal region but not to reach an end edge of the terminal region. | 2008-12-18 |
20080309651 | DRIVE CONTROL CIRCUIT DEVICE FOR FLAT PANEL DISPLAY APPARATUS - Provided is a technology related to a PDP apparatus and capable of realizing the efficiency improvement in the processing of a control circuit including the processing between a control circuit (waveform generating circuit unit) and a non-volatile memory (waveform ROM). In a control circuit of a PDP apparatus, an SFM (serial flash memory) is used as a non-volatile memory, and waveform decoding data and a waveform decoding address set are stored as a first waveform in the SFM. An LSI (waveform generating circuit LSI) stores the data from the waveform decoding data in a first SRAM in an internal SRAM unit and stores the data corresponding to one reading cycle (for example one SF) selected from the waveform decoding address set in a second SRAM in the internal SRAM unit. | 2008-12-18 |
20080309652 | ADAPTIVE REFRESH RATE FEATURES - A device may include a display capable of providing variable refresh rates, and a display controller that determines a refresh rate and outputs an image to the display based on the determined refresh rate. | 2008-12-18 |
