| 20100066923 | DISPLAY DEVICE, ITS DRIVING CIRCUIT, AND DRIVING METHOD - The present invention relates to a display device and, more particularly, to an active matrix-type display device employing a line inversion drive scheme as a drive scheme. | 03-18-2010 |
| 20100195004 | LIQUID CRYSTAL DISPLAY REORDERED INVERSION - Methods and apparatus for switching the voltages supplied to the electrodes of pixels disposed within a liquid crystal display device. By reducing the frequency associated with an alternating voltage supplied to a first set of liquid crystal electrodes, the power required to drive the liquid crystal display device can be reduced. At the same time, a reordered schedule for updating rows of pixels in the liquid crystal display device can provide improved image quality. | 08-05-2010 |

| 20100309394 | DISPLAY DEVICE AND DRIVE METHOD FOR THE SAME - At least one embodiment of the present invention aims to provide a display device capable of compensating for a change of a liquid crystal capacitance value for an electro-optic element such as a liquid crystal in accordance with a change of an application voltage to the electro-optic element, without incorporating frame memory. It also aims to improve the response speed of a display device without frame memory. For each pixel formation portion, a frame period is divided into first and second periods. During a frame period in which a target voltage having one of the positive and negative polarities with respect to a potential (Com) of an opposing electrode is to be applied to a pixel electrode, during the first period, a TFT is brought into conductive state and a voltage corresponding to the target voltage is applied to a source line (Sj), thereby providing the pixel electrode with a voltage of the other polarity with respect to the potential (Com) of the opposing electrode, while during the second period, the TFT is brought into non-conductive state and the voltage on an auxiliary capacitance line (Ck) is caused to change from the other polarity to one polarity with respect to the potential of the opposing electrode. | 12-09-2010 |
