摘要： 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 (ΔVcs) 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.

摘要： 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.

摘要： This display device has a demultiplexer (501) formed on a liquid crystal panel, the demultiplexer including three switching elements SW1 to SW3 for time-division drive, which are connected to video signal lines SL1 to SL3. Here, the number of switching control signal lines for transmitting switching control signals GS1 to GS6 to be provided to switching elements coupled to the video signal lines is six, which is twice the number of time divisions, and switching control signals (e.g., GS1 and GS4) with the same timing are individually transmitted by two switching control signal lines, so that the number of switching elements to be coupled to the switching control signal lines as loads can be halved, resulting in reduced waveform rounding of the control signals.

摘要： In one embodiment of the present invention, the present shift register is a shift register provided in a display device by which a partial-screen display is available. The shift register includes a shift stopping circuit that is provided in an in-between stage, and stops operation of the shift register between a first stage and a last stage of the shift register in partial-screen display. The shift register also includes a circuit that is provided in a stage other than the in-between stage in such a manner that the circuit does not perform signal processing but serves as a signal path. The circuit is same as the shift stopping circuit in configuration. The foregoing allows improvement in display quality of the display device employing the present shift register.

摘要： A level shift circuit includes first and second level shifters which respectively output first and second output signals that are produced by level shifting two kinds of input clock signals whose high level periods do not overlap. The level shift circuit also includes control transistors and control lines which, together, prevent a feedthrough current from flowing into the second level shifter when the first output signal is high level, and prevent a feedthrough current from flowing into the first level shifter when the second output signal is high level, so as to suspend the level shift operation of the first and second level shifters. With the level shift circuit, power consumption during a specific time period in a non-active period of the clock signal can be eliminated, where the specific time period of one clock signal is the active period of the other clock signal.
