| 20110102422 | TWO-DIMENSIONAL/THREE-DIMENSIONAL IMAGE DISPLAY APPARATUS AND METHOD OF DRIVING THE SAME - A display apparatus which displays two-dimensional (2D) and three-dimensional (3D) images and a method of driving the same. In the 2D/3D image display apparatus, an image signal input unit inputs, to a display panel, a left image signal, a left inversion image signal, at least one 2D image signal, a right image signal and a right inversion image signal, a left shutter of shutter glasses is open in synchronization with the left image signal, a right shutter of the shutter glasses is open in synchronization with the right image signal, and the left shutter and the right shutter of the shutter glasses are closed in synchronization with the left inversion image signal, the at least one 2D image signal, and the right inversion image signal. | 05-05-2011 |
| 20110148863 | 3D DISPLAY DRIVING METHOD AND 3D DISPLAY APPARATUS USING THE SAME - A method for driving a 3D display and a display apparatus using the same are provided. The display apparatus includes a storage unit to store a received image and a controlling unit to drive a display by adjusting the brightness value using a first look-up table when the previous frame is different from the current frame and adjusting the brightness value using a second look-up table when the previous frame is the same as the current frame. According to the exemplary embodiment, an overdrive method may be applied to a 3D image display apparatus effectively. | 06-23-2011 |
| 20110148943 | METHOD FOR DRIVING THREE-DIMENSIONAL (3D) DISPLAY AND 3D DISPLAY APPARATUS USING THE SAME - A method for driving a three dimensional (3D) display and a 3D display apparatus using the same are provided. The 3D display apparatus includes a storage unit which stores a received image; and a controller which compares a previous frame of the received image with a current frame of the received image, and determines whether or not to input an image of the current frame to a liquid crystal panel based on whether the previous frame is identical to the current frame. Therefore, a method for driving a 3D display which does not cause characteristics of a liquid crystal to be deteriorated and a 3D display apparatus using the same are provided. | 06-23-2011 |
| 20110157165 | METHOD AND APPARATUS FOR DISPLAYING 3-DIMENSIONAL IMAGE AND METHOD AND APPARATUS FOR CONTROLLING SHUTTER GLASSES - An image display method includes alternately receiving left and right images of a 3D image; and turning on a backlight such that the backlight is on only in periods when the left images are displayed or only in periods when the right images are displayed. A method of controlling shutter glasses separately for left and right images of a three-dimensional (3D) image includes alternately receiving the left and right images of the 3D image; and opening two shutters of the shutter glasses only in periods when the left images are received or only in periods when the right images are received. | 06-30-2011 |
| 20110193897 | METHOD AND APPARATUS FOR CONTROLLING THE PARTITIONS OF A BACKLIGHT UNIT OF A 3D DISPLAY APPARATUS - A method and apparatus for controlling a backlight unit of a three-dimensional (3D) display apparatus receiving a 3D video sequence is provided. The method includes determining the image brightness level of the 3D video sequence displayed on a liquid crystal display (LCD) unit, for each of a plurality of partial regions of the LCD unit to which a plurality of sub-blocks of the backlight unit emit light; determining turn-on times of the plurality of sub-blocks of the backlight unit, based on the image brightness of each of the partial regions of the LCD unit; and determining turn-on periods of the plurality of sub-blocks of the backlight unit by synchronizing with a switching period between a set including a left visual point frame and a right visual point frame of the 3D video sequence. | 08-11-2011 |
