摘要： An input buffer chooses, in accordance with first control clocks, to output an input data signal or output a high-impedance signal. A master flip-flop chooses, in accordance with second control clocks, to output a data signal received from the input buffer or retain a currently output data signal. A master-slave switch chooses, in accordance with the second control clocks, to output a high-impedance signal or output a data signal received from the master flip-flop. A slave flip-flop chooses, in accordance with the second control clocks, to retain a currently output data signal or output a data signal received from the master-slave switch. A clock buffer inputs the second control clocks, and generates and outputs the first control clocks.

摘要： A liquid crystal display is provided which has low power consumption, and which prevents horizontal stripes from occurring without the circuitry becoming more complex. When the write voltage polarity is inverted every plurality of lines, in the n line where the polarity is inverted, the rise in the drain line waveform dulls due to the charging of the drain line. In the n+1 line, because the drain line has been charged by the writing of the n line, waveform dullness does not occur. A difference between the write states in the two lines causes horizontal stripes. Consequently, the output enable signal is activated at the rise of the clock signal, and the gate line is activated after a predetermined time to start the writing. Therefore, writing is not performed during the period of waveform dullness, and the write state is the same across all scan lines.

摘要： An active matrix-type liquid crystal display device which is capable of realizing a dot inversion driving by disposing H drivers on both sides of the liquid crystal panel, while using existing H driver circuits which output odd output data and even output data at opposite polarities to each other. The first and second H drivers, which output odd output data and even output data at opposite polarities to each other, are disposed facing each other on both sides of the liquid crystal panel, in order to realize an active matrix-type liquid crystal display device which is conducted by the dot inversion driving. Data electrodes of said liquid crystal display device are taken out for every two lines or every integer times of two lines and the thus taken out data lines are connected alternately to the first and second driver circuits.
