| 20100045087 | Side Bolster Apparatus for Automobile Seat - The side bolster apparatus includes a pressing unit formed on one side of a foldable seat back and rotating around a rotating shaft of the seat back, bolster installed so as to protrude from a rear side of the seat back, and an external force transmitting unit receiving external force from the pressing unit when the seat back is unfolded and transmitting the received external force to the bolster such that the bolsters protrude from the seat back. | 02-25-2010 |
| 20100140905 | Seat Cover for Vehicle and Seat Having the Same - The present invention provides a seat cover for a vehicle which is configured such that when a side airbag is initially deployed, an airbag can be smoothly guided in a lateral direction. The seat cover includes a front sheet, a rear sheet and a side sheet. A reinforcing fabric is provided on an inner surface of the front sheet. The side sheet is sewn at a first edge thereof to the front sheet and sewn at a second edge thereof to the rear sheet. A reinforcing liner is adhered or welded to an inner surface of the side sheet. The reinforcing fabric is less extensible or stretchable than the reinforcing liner. | 06-10-2010 |

| 20110175547 | BACKLIGHT UNIT, DRIVING METHOD THEREOF, AND ERROR DETECTION METHOD THEREOF - A backlight unit includes a driving circuit, a plurality of light source strings, and an error detector. The driving circuit outputs a driving voltage. Each of the light source strings includes a plurality of light sources and receives the driving voltage through input terminals of the light source strings to generate a light. The error detector is connected to output terminals of the light source strings and senses voltages between the input terminals and the output terminals of the light source strings to detect an error in the light sources using a first voltage and a second voltage. The first voltage is a voltage difference between a maximum and a minimum of the sensed voltages and the second voltage is obtained by dividing one sensed voltage of the sensed voltages by a number of the light sources of a light source string from which the one sensed voltage is sensed. | 07-21-2011 |
| 20110249033 | METHOD OF DRIVING BACKLIGHT ASSEMBLY AND DISPLAY APPARATUS HAVING THE SAME - A backlight assembly outputs scan signals having a scanning frequency synchronized with a frame frequency to sequentially drive light emitting blocks providing a light to a display panel. A dimming step of each light emitting block corresponds to one of a plurality of dimming steps in response to local dimming data. A dimming clock having a value obtained by dividing a value obtained by multiplying the scanning frequency and the number is dimming steps by a duty ratio of each scan signal is generated. The dimming step of each light emitting block is counted using the dimming clock, and the counted values are combined with the scan signals to generate dimming signals having a dimming duty ratio corresponding to the dimming step of the light emitting blocks. | 10-13-2011 |
| 20110279485 | DISPLAY APPARATUS - A display apparatus includes a backlight unit which emits a light, and a display panel which receives the light to display an image. The backlight unit includes a driving circuit which outputs a driving voltage and a reference voltage; and p light source blocks connected to the driving circuit, p being a natural number greater than or equal to 2, where each light source block of the p light source blocks receives the driving voltage through a first terminal thereof and the reference voltage through a second terminal thereof to generate the light, and the p light source blocks are divided into a plurality of groups, each group including at least two light source blocks. The driving circuit includes a first switching section which applies the driving voltage to first terminals of the p light source blocks, and a second switching section which applies the reference voltage to the second terminal of at least one of the p light source blocks. | 11-17-2011 |

| 20090153068 | BACKLIGHT ASSEMBLY, DISPLAY APPARATUS HAVING THE BACKLIGHT ASSEMBLY, AND METHOD THEREOF - A backlight assembly includes a light-generating unit and an inverter. The light-generating unit includes a first U-shaped lamp and a second U-shaped lamp parallel with each other. Electrodes of the first and second U-shaped lamps are disposed at one side of the light-generating unit. The inverter includes a multi-output transformer, a first output terminal and a second output terminal. The multi-output transformer generates a first driving voltage and a second driving voltage having a phase opposite to a phase of the first driving voltage. The first and second output terminals electrically connect the first and second U-shaped lamps with the multi-output transformer. The multi-output transformer applies the first and second driving voltages to the first and second U-shaped lamps via the first and second output terminals. | 06-18-2009 |
| 20110101874 | METHOD OF DRIVING LIGHT SOURCE AND DISPLAY APPARATUS FOR PERFORMING THE METHOD - A method of driving a light source apparatus includes inverting a direct current voltage to generate a first alternating current voltage, transforming the first alternating current voltage into a second alternating current voltage having a voltage level that is greater than a voltage level of the first alternating current voltage, compensating a driving alternating current voltage based on the second alternating current voltage to generate a compensated driving alternating current voltage such that a substantially equal current flows through each light emitting string of a plurality of light emitting string included in the light source apparatus, and rectifying the compensated driving alternating current voltage to apply a driving voltage to the light emitting strings. | 05-05-2011 |
