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.

摘要： A color display pixel PCD in a liquid crystal display device (100) includes first through fourth pixels P1 through P4 arrayed in two rows by two columns, and first and second signal lines (13a, 13b) which are located in correspondence with each column of pixels and are supplied with signal voltages of polarities opposite to each other from a signal line driving circuit (30) in each vertical scanning period. A TFT (14) of one of the first and third pixel P1 and P3 is connected to the first signal line (13a), and a TFT (14) of the other pixel is connected to the second signal line (13b). A TFT (14) of one of the second and fourth pixel P2 and P4 is connected to the first signal line (13a), and a TFT (14) of the other pixel is connected to the second signal line (13b). The TFTs (14) of the first through fourth pixels P1 through P4 are controlled to be ON/OFF by a common scanning signal, and the polarities of the signal voltages supplied to the first and second signal lines (13a, 13b) are constant during an arbitrary vertical scanning period. Owing to this, the load on the signal line driving circuit is reduced.

摘要： The vertical scan period of the input video signal is divided into at least two sub-frames. In each of the sub-frames, a display signal voltage is written into each pixel. Two vertical scan periods in which the input video signals are continuous contain a sequence of two continuous sub-frames where a display signal voltage is written with the same polarity and a sub-frame where the polarity of the display signal voltage is inversed. The auxiliary capacity opposing voltage includes, in each of the sub-frames, a first waveform vibrating with a first cycle of the horizontal scan period multiplied by an integer not smaller than 2 and a second waveform in which an effective value of the auxiliary capacity opposing voltage is set to a predetermined constant value for each vertical scan period of a predetermined number of continuous input video signals.
