| 20100309374 | DISPLAY DEVICE AND DRIVING METHOD THEREOF - A display device and a driving method thereof where different sounds are output depending upon characteristics of display images. The display device includes a display unit having a plurality of pixels, a signal controller, and a sound controller. The display unit displays images by selectively activating pixels from among the plurality of pixels in accordance with input video signals and input image control signals. The signal controller reads the input video signals to generate on-pixel signals having information about a ratio of a number of the activated pixels compared to a total number of pixels in the plurality of pixels per each frame and generating a sound output start signal. The sound controller determines a range from among predetermined ratio ranges corresponding to the ratio of the number of active pixels to define a plurality of volume levels, and determining the volume level corresponding to the on-pixel signal so as to generate a sound output instruction signal corresponding to the determined volume level. | 12-09-2010 |
| 20100310094 | DISPLAY DEVICE AND DRIVING METHOD THEREOF - A display device and a method of driving the display, wherein the volume of background music is controlled depending upon the color or brightness of display images, and the power consumption is reduced. The display device includes a display unit with a plurality of pixels, a signal controller, and a volume controller. The display unit displays images by selectively activating pixels from among the plurality of pixels in accordance with input video signals and input image control signals. The signal controller reads the input video signals to generate on-pixel signals having information about the ratio of a number of the active pixels compared to a total number of pixels in the plurality of pixels per each frame. The volume controller determines a range from among predetermined ratio ranges corresponding to the ratio of the number of active pixels to define a plurality of volume levels, and determine the volume level corresponding to the on-pixel signal to control the volume according to the ratio corresponding to the determined volume level. | 12-09-2010 |
| 20110025597 | Digital display device and image arrangement method using the same - A digital display device that implements a digital photo frame function. The digital display device includes a user input unit to receive control signals corresponding to a user operation, the control signals to control a plurality of images to be continuously displayed, a display controller including an image arrangement unit, the display controller to output display signals by storing image files or processing the stored image files according to the control signals, a storage unit having image files stored therein and a display unit to display the plurality of images on a screen according to the display signals, the image arrangement unit to arrange the plurality of images in an arrangement order for display based on comparison results that compare data for pairs of images selected from the plurality of images upon the control signals being input. | 02-03-2011 |

| 20080272602 | Wind Turbine - Disclosed is a wind turbine, in which the assembly of a rotor and a stator of a generator with a main shaft connecting a turbine rotor and the generator is completed only by assembling the rotor of the generator with the main shaft without assembling the stator of the generator with the main shaft. In the wind turbine, a rotor bearing being perpendicular to a vertical rotor frame is formed integrally with the rotor of the generator and is connected to the outer surface of the main shaft, a pair of electric bearings is disposed at the outer surface of the rotor bearing, and the stator of the generator is assembled with the rotor of the generator by fixing a stator housing to bearing housings of the electric bearings. Thereby, convenience and efficiency in assembly are increased. | 11-06-2008 |
| 20090250935 | ROTOR FOR WIND TURBINE AND ASSEMBLING METHOD THEREOF - Disclosed is a rotor for a wind turbine, which prevents permanent magnets from being separated from the rotor due to the melting of portions of the permanent magnets bonded to the rotor by a high temperature atmosphere without burying the permanent magnets in the rotor. The rotor includes a circular body provided with grooves having a trapezoidal shape, horizontally formed in the outer circumferential surface of the circular body, and spaced at regular intervals, the central portion of the circular body being connected to a rotary shaft; permanent magnets having a trapezoidal shape and detachably inserted horizontally into the grooves; and fixing rings detachably installed respectively on the front and rear surfaces of the circular body so as to be closely attached to the front and rear surfaces of the permanent magnets to fix the permanent magnets. | 10-08-2009 |
| 20100219642 | WIND TURBINE WITH SINGLE MAIN BEARING - Disclosed is a wind turbine comprising a nacelle frame provided with one main bearing on the front surface thereof; a rotor including a rotor hub provided with a hollow drum shaft, installed on the inner ring of the main bearing, at the rear thereof; an acceleration gear box including an input shaft, connected to the tip of the hollow drum shaft, at the front portion thereof and an output shaft at the rear portion thereof, and floating in the nacelle frame under the condition that the acceleration gear box is separated from the nacelle frame for increasing the rotational speed of the input shaft and transmitting the rotation of the input shaft to the output shaft; a torque supporter installed between the acceleration gear box and the nacelle frame for preventing the acceleration gear box from self-rotating; and a generator including a rotary shaft connected to the output shaft. | 09-02-2010 |
