20130222355 | ELECTROWETTING DISPLAY DEVICE AND DRIVING METHOD THEREOF - The present invention applies the voltage that is swung to the notch electrode of each pixel of the electrowetting display device to reset the oil layer to not backflow such that an additional element is not disposed in the pixel, thereby increasing the aperture ratio of the pixel. Also, the reset signal generator generating and applying the reset signal is disposed inside the electrowetting display device such that additional wiring may not be disposed in the outer part of the panel. | 08-29-2013 |
20130257914 | ELECTROWETTING DISPLAY DEVICE - A display device includes a display capacitor, a data switching device, and a reset switching device. The data switching device may transmit a data voltage to the display capacitor in response to an activating gate signal that is applied to the data switching device for a activating gate signal duration. The reset switching device may transmit a storage voltage to the display capacitor in response to an activating reset signal that is applied to the first reset switching device for an activating reset signal duration. The storage voltage is configured for resetting a pixel associated with the first display capacitor. The activating reset signal duration is longer than the activating gate signal duration. | 10-03-2013 |
