20130207944 | DISPLAY DEVICE - Each of a plurality of timing controllers has a synchronization reference signal output terminal from which a synchronization reference signal is output and a synchronization reference signal input terminal to which the synchronization reference signal is input. A master timing controller outputs a predetermined signal of display signals which are input from an external device, from the synchronization reference signal output terminal of the master timing controller as the synchronization reference signal, and the synchronization reference signal is input to the synchronization reference signal input terminals of the master timing controller and a slave timing controller. Accordingly, a luminance difference can be prevented from occurring between divided regions of a display panel due to asynchronization between display signals input to respective timing controllers in a display device in which a plurality of timing controllers are used and the display panel is divided into a plurality of regions. | 08-15-2013 |

20130215373 | DISPLAY DEVICE - In a three-dimensional display device using a liquid crystal lens, a planer electrode is formed on an upper substrate of the liquid crystal lens and strip-like electrodes are formed on a lower substrate of the liquid crystal display lens. The distance between the upper and lower substrates is provided by a bead. At this time, if the bead is present on the strip-like electrode, the lens formed thereon is distorted. In order to prevent this, a bump is formed to cover the strip-like electrode. The distance between the bump and the upper substrate is small, so that the bead is pushed out of the upper part of the strip-like electrode, preventing the lens from being distorted. As a result, it is possible to prevent the crosstalk caused by the lens distortion due to the presence of the bead on the strip-like electrode. | 08-22-2013 |
