The driving circuit is further configured to periodically provide a reset signal to the electrowetting pixel while the electrowetting pixel is displaying the image and provide an image stored in the memory circuit to the electrowetting pixel after the electrowetting pixel cell resets. | 06-05-2014 |
20140232325 | DISPLAY DEVICES, WIRELESS CHARGING SYSTEM INCLUDING DISPLAY DEVICES, AND METHODS OF OPERATING THE DISPLAY DEVICES - A display device includes a display panel including at least one electrode, and a panel driving unit configured to drive the display panel. The display device further includes a power storage unit configured to store received power, and a switching unit configured to electrically connect the at least one electrode to one of the panel driving unit and the power storage unit. | 08-21-2014 |
20140253481 | APPARATUS AND METHOD FOR SENSING TOUCH AND TOUCH SCREEN APPARATUS EMPLOYING THE SAME - The touch sensing apparatus includes a driving unit and a touch sensing unit, a scan region selecting unit, and a control unit. The driving unit and the touch sensing unit arranged at a touch panel are electrically connected to driving electrodes and sensing electrodes, respectively. The scan region selecting unit controls the driving unit and determines a narrowed scan region including a touched location by dividing a touch region of the touch panel into a plurality of scan regions, scanning each of the scan regions, and selecting a scan region including the touched location at least for once. The control unit controls the scan region selecting unit and the driving unit and determines the narrowed scan region including the touched location and sense the touched location by inputting signals in a time-division manner to a plurality of scan lines included in the narrowed scan region. | 09-11-2014 |
