20100097367 | LIQUID CRYSTAL DISPLAY DEVICE, SCAN SIGNAL DRIVE DEVICE, LIQUID CRYSTAL DISPLAY DEVICE DRIVE METHOD, SCAN SIGNAL DRIVE METHOD, AND TELEVISION RECEIVER - In one embodiment of the present invention, a liquid crystal display device is disclosed in which a gate driver applies a gate-on pulse so that a second period is longer than a first period. The first period and the second period are defined as follows. Among gate-on pulses applied before the moment of polarity inversion of a data signal, the last end of the gate-on pulse nearest to the moment of the polarity inversion is earlier than the end time of the horizontal period during which the gate-on pulse is applied. The first period starts at the last end of the gate-on pulse and ends at the end time of the horizontal period during which the gate-on pulse is applied. The second period starts at the moment of the polarity inversion and ends at the moment of the application start of the gate-on pulse nearest to the moment of the polarity inversion among the gate-on pulses applied after the polarity inversion. Thus, even when a data signal waveform is not sharp upon polarity inversion, it is possible to suppress display unevenness and perform a high-quality display. | 04-22-2010 |

20100118013 | LIQUID CRYSTAL DISPLAY DEVICE, LIQUID CRYSTAL DISPLAY DEVICE DRIVE METHOD, AND TELEVISION RECEIVER - In one embodiment of the present invention, a gate driver creates a dummy insertion period in which the driver does not apply a gate on pulse to a scanning signal line immediately after the time of the inversion of a data signal. When a period from the time of the application of the gate on pulse to an odd numbered or even numbered scanning signal line to which the gate on pulse is applied previously to the time of the application of the gate on pulse to an even numbered or odd numbered scanning signal line to which the gate on pulse is applied later is set as an adjacent line writing time lag period for two scanning signal lines adjacent to each other, a CS control circuit allows the polarity of every CS signal to be reversed on the same cycle at least in the adjacent line writing time lag period. This makes it possible to provide a liquid crystal display device capable of offering high quality display in which unevenness in the display is suppressed without being affected by the blunt waveform of the data signal and the blunt waveform of a retention volume signal at the time of the inversion. | 05-13-2010 |
