  • Patent number: 8791895
    Abstract: In a memory liquid crystal display device, a potential of a storage capacitor line signal (CS) supplied to the CS lines (CSL(i)) are once decreased (?Vcs) while the gate lines (GL(i)) are made simultaneously active (period t4, period t10) in the data holding period (T2), and the potential of the storage capacitor line signal (CS) is made back to its original potential while the gate lines (GL(i)) are made simultaneously inactive and the refresh output control lines (RC(i)) are made active (period t5, period t11). This reduces flicker, thereby allowing for improvement in display quality of the memory liquid crystal display device.

  • Patent number: 8736534
    Abstract: In one embodiment of the present invention, on each source bus line, an electric charge escaping transistor is provided having the same polarity as a pixel transistor and having a gate to which a turn-off voltage signal of the pixel transistor is supplied. When an active matrix liquid crystal display device is powered off, the turn-off voltage signal is made to reach the GND level before a turn-on voltage signal of the pixel transistor reaches the GND level, so that the pixel transistor and the electric charge escaping transistor are made half-open. This lets electric charges accumulated in the pixel escape to a common electrode TCOM.
