| 20080316149 | Electro-luminescence pixel, panel with the pixel, and device and method for driving the panel - An electro-luminescence display having a plurality of pixels is disclosed. One of the pixels of the electro-luminescence display includes an electro-luminescence diode electrically connected between first and second voltage sources; first and second thin film transistors adjusting an amount of current flowing to the electro-luminescence diode; and a control circuit complementarily operating the first and second thin film transistors in an active mode and a refresh mode. | 12-25-2008 |
| 20100085374 | LIQUID CRYSTAL DISPLAY DEVICE AND DRIVING METHOD THEREOF - An LCD device with an improved contrast ratio and a reduced electric power consumption and a driving method thereof are disclosed. The LCD device and the driving method thereof generate a data modulation control signal using single frame image data to be displayed on a liquid crystal panel, and then generating a plurality of modulated local dimming control signals for a plurality of divisional regions of the divided single frame image data. A modulated data, in which the single frame image data is compensated with the data modulation control signal is generated and applied to the liquid crystal panel. A plurality of driver signals each corresponding to the modulated local dimming control signals are applied to the blocks of a backlight unit. The divisional regions are opposite to the blocks, respectively. | 04-08-2010 |

| 20100027910 | METHOD FOR MINIMIZING DATA TRANSITION AND CIRCUIT FOR MINIMIZING DATA TRANSITION - A data transition minimization method includes exclusive-NORing inputted nth image data (where n is a natural number) and (n−m)th image data (where m is a natural number smaller than n) expressing the same color as that of the nth image data to generate transition information data; generating inversion data indicative of inversion information by inverting all bits included in the transition information data and adding a unit bit having the logic value ‘1’ to the inverted transition information data when the number of unit bits having a logic value ‘1’ in the transition information data is larger than the number of unit bits having a logic value ‘0’ in the transition information data, and adding a unit bit having the logic value ‘0’ to the transition information data when the number of unit bits having the logic value ‘I’ in the transition information data is equal to or smaller than the number of unit bits having the logic value ‘0’ in the transition information data; exclusive-NORing the transition information data with the inversion data added and corrected image data of (n−1)th image data to generate corrected image data of the nth image data, and supplying the generated corrected image data to a data driver through data transmission lines; and restoring the corrected image data supplied to the data driver to restored image data corresponding to the original nth image data. | 02-04-2010 |

| 20110199196 | Integrated remote controller and method of selecting device controlled thereby - An integrated remote controller and a method of selecting a device controlled thereby are disclosed. The present invention is implemented such that it can store position data of devices to be controlled by the integrated remote controller; recognize devices around the integrated remote controller and displaying the devices; determine as to whether an angular velocity of the integrated remote controller is varied, if the recognized devices are plural; if the angular velocity is varied, sense movement direction of the integrated remote controller based on the angular velocity to search for a device to be controlled by a user; and display a control menu of the device to be controlled by the user. | 08-18-2011 |
