| titleOfInvention | Liquid crystal display apparatus and its drive method |
| abstract | The liquid crystal display apparatus includes the followings: liquid crystal panel, which has M switching devices as well as pixel portions of liquid crystal in the horizontal direction, and N switching devices as well as pixel portions of liquid crystal in the vertical direction; drive circuit of signal line, which inputs display data and generates the class voltage corresponding to the input display data so as to apply the class voltage to the pixel portion of the horizontal direction corresponding to the display data; and the scan drive circuit, which sequentially selects one of the pixel portions arranged in the vertical direction and adds the selection voltage to the selected pixel portions arranged in the vertical direction while adds color-mixed non-selection voltage to the non-selected pixel portions arranged in the vertical direction. The liquid crystal is provided with the counter electrodes commonly used for each pixel. When the switching device is added with the selection voltage of the scan drive circuit, the counter electrodes add the class voltage generated by the signal line drive circuit to the liquid crystal so as to use the effective voltage value of the class voltage of the counter electrodes to control the display brightness of the liquid crystal display apparatus. The apparatus is provided with a circuit that generates AC signal for indicating the alternation of the counter voltage added to the counter electrodes and the compensation period signal for expressing the period of adding the compensation voltage to the counter voltage added to the counter electrode. In addition, the liquid crystal display apparatus is provided with the counter electrode voltage generation circuit that has the followings characteristics: adding AC counter electrode voltage to the counter electrodes based on the AC signal and the compensation period signal; increasing the compensation voltage extruding upwards when the counter electrode voltage is a positive voltage; and decreasing the compensation voltage extruding upwards when the counter electrode voltage is a negative voltage. |
