  • Patent number: 7834869
    Abstract: A display panel driver has two driver circuits that drive separate halves of a display panel. Each driver circuit occupies a separate integrated circuit chip. The driver has a screen saving mode in which each driver circuit displays an independent screen saving image that moves in synchronization with a timing signal. The timing signal is generated in one driver circuit and transmitted by a chip-to-chip interface to the other driver circuit. The two screen saving images are thereby coordinated to create what appears to be a single screen saving display.

  • Patent number: 7796115
    Abstract: Bi-stable electrophoretic display device (1) having a normal mode and a scrolling mode, in which image transitions are effected by causing the charged particles (8,9) to toggle between the intermediate optical states (e.g. grey-to-grey) or between an extreme optical state and an intermediate optical state (e.g. white-to-light grey), with a corresponding short update time tscroll. When the device (1) enters a scrolling mode in response to a scrolling command from a user, picture elements are first driven to a special scrolling optical. state, after which drive waveforms for scrolling mode are used for fast toggling between two scrolling states. An increased scrolling speed and very short scrolling time can be realized, without adversely affecting image quality during a normal mode.

  • Patent number: 7791596
    Abstract: A touch input device includes two or more interleaved scroll sensors. A common area is interposed between two of the scroll sensors. A sense line snakes through the common area. Scrolling pressure applied to a sense layer causes the sense layer to contact and electrically connect the sense line to the scroll sensors thereby permitting the scrolling pressure position to be determined by measuring a voltage on the sense line. The scroll sensors are potentiometric and may be linear strip scroll sensors or rotary ring scroll sensors. The interleaved scroll sensors with the common area allow smooth scrolling action from one major leg to another major leg.

  • Patent number: 7786959
    Abstract: When the transistor Q3 is OFF, a predetermined potential is supplied to a potential wire Ui such that a switching transistor Q2 becomes ON. This changes a gate potential of a driving transistor Q1 from an ON potential to a threshold potential. Thereafter, the transistor Q2 is turned OFF, with the result that the potential of the potential wire Ui is changed (in cases where the transistor Q1 is a p-type transistor, the potential is decreased). With this, the transistor Q1 allows a current to constantly flows therethrough, irrespective of the threshold potential. This shortens time for setting an output current of the driving TFT for driving a current driving type display element.
