20100328328HYBRID ELECTRIC DEVICE USING PIEZO-ELECTRIC POLYMER SUBSTRATE AND ITS FABRICATION METHOD - The present invention relates to an integrated, composite hybrid electric device in which various devices are formed as a single unit on one flexible substrate, and a fabrication method thereof. More particularly, the present invention a hybrid electric device in which a display device, a vibration-generating (or vibration-sensing) device, and a non-volatile memory device are formed on a single flexible piezoelectric polymer substrate into a single unit by using a flexible piezoelectric polymer substrate whose both surfaces are thinly deposited with a patterned transparent oxidation electrode, and a fabrication method thereof.12-30-2010
20080297524Liquid crystal display with symbol bit generating circuit and driving method thereof - An exemplary liquid crystal display includes a data circuit, a memory, and a timing controller. The data circuit includes a polarity generating circuit. The timing controller includes: a data analysis circuit configured for analyzing video signals stored in the memory and generates a corresponding symbol bit to each datum according to the category of each datum; and a symbol bit generating circuit configured for receiving the video data from the data analysis circuit, and keeping or altering the symbol bit of each datum according to the symbol bit of each datum outputted from the data analysis circuit. The data circuit is configured for receiving the video data having symbol bits from the timing controller. The polarity generating circuit is configured for generating a corresponding polarity control signal according to each of the symbol bits of the video data. A related method for driving the liquid crystal display is also provided.12-04-2008
20080297523IMAGE DISPLAY SYSTEM, GAME MACHINE, IMAGE DISPLAY METHOD, IMAGE DISPLAY PROGRAM, AND RECORDING MEDIUM - An image display system includes: a background image transfer section which commands the image producing unit to produce a background image corresponding to the background image data and transfer the background image to the resolution adjusting unit; a window display image transfer section which commands the image producing unit to produce a window display image corresponding to the window display image data and transfer the window display image to the resolution adjusting unit; and a display control section which controls the process of the resolution adjusting unit for outputting the image stored in the virtual image storing unit.12-04-2008
20130187937ELECTRONIC DEVICES CONFIGURED FOR ADAPTING REFRESH BEHAVIOR - A method for adapting refresh behavior on an electronic device is described. The method includes operating according to an adaptive state that adapts a refresh rate for a display based on at least one frame. The method additionally includes transitioning from the adaptive state to a self refresh state based on a first self refresh state indication. The method further includes transitioning from the self refresh state to the adaptive state based on a second self refresh state indication.07-25-2013
