摘要： Each pixel includes first and second subpixels and two switching elements provided for those subpixels. Each subpixel includes a liquid crystal capacitor and a storage capacitor. The storage capacitor counter electrodes of the first and second subpixels are electrically independent. A storage capacitor counter voltage applied to each storage capacitor counter electrode by way of its associated storage capacitor line has a first period (A) with a first waveform during one vertical scanning period. The first waveform oscillates between multiple voltage levels in a first cycle time (PA) that is an integral number of times (and at least four times) as long as one horizontal scanning period (H). Each of the voltage levels has a flat portion with a duration TP. While the two switching elements are ON, a display signal voltage is applied to the respective subpixel electrodes and respective storage capacitor electrodes of the first and second subpixels. After the two switching elements have been turned OFF, voltages at the storage capacitor counter electrodes of the first and second subpixels change. And if an interval between a point in time when the two switching elements in ON state have just been turned OFF and a point in time when the storage capacitor counter voltage changes for the first time is βH, TP/4≦β

摘要： A voltage corresponding to a black display is applied in a part of one frame period. When a black signal insertion period is changed, the black signal insertion period after the change is controlled so that (i) a time from a position at which a signal voltage of a first or second storage capacitor line rises to a position at which a first black insertion pulse rises in the black signal insertion period before the change becomes equal to (ii) a time from a position at which a signal voltage of the first or second storage capacitor line rises to a position at which a first black insertion pulse rises in the black signal insertion period after the change. This makes it possible to provide an active matrix type liquid crystal display device capable of preventing the occurrence of a difference in luminance between an upper side of a display panel screen and a lower side of the display panel screen in a case where black insertion is carried out with respect to a display panel which forms bright and dark sub-pixels by changing, for every sub-pixel, an effective voltage to each pixel by capacitive coupling of a storage capacitor and a liquid crystal capacitor, and a drive method of the active matrix type liquid crystal display device.

摘要： Each pixel includes first and second subpixels with different luminances. Each subpixel includes a liquid crystal capacitor and a storage capacitor. The storage capacitor counter electrodes of the subpixels (such as those of the first subpixel of an arbitrary pixel and the second subpixel of a vertically adjacent pixel) are electrically independent. A storage capacitor counter voltage supplied through each storage capacitor trunk has a first period (A) with a first waveform and a second period (B) with a second waveform within one vertical scanning period (V-Total) of an input video signal, where V-Total=A+B. The first waveform oscillates between first and second voltage levels in a first cycle time PA, which is an integral number of times, and at least twice, as long as one horizontal scanning period (H). The second waveform is defined such that the effective value of the storage capacitor counter voltage has a predetermined constant value every predetermined number of (but 20 or less) consecutive vertical scanning periods. Thus, the viewing angle dependence of the γ characteristic can be reduced.
