Display apparatus

A liquid crystal display apparatus comprising:

• a liquid crystal display panel having a display area (h×w) and a cell gap (a), and including electrodes arranged in a matrix form, and a liquid crystal disposed in the cell gap so as to form pixels in combination with the electrodes, the electrodes arranged in a matrix form comprising a number (Nc) of scanning electrodes each having a resistance (Rt) and a capacitance (Ct), and a number of data electrodes;
• signal waveform-generating means for generating a signal waveform supplied to the scanning electrodes and the data electrodes, said signal waveform-generating means including rectangular signal waveform-generating means for generating a rectangular drive signal waveform having a rising portion and a falling portion supplied to the scanning electrodes;
• split pulse-generating means for generating split pulses including a frequency component exceeding a prescribed cut-off frequency (f);
• superposing means for superposing the split pulses with the rising and falling portions of the signal waveform;
• and
• integration means for integrating the signal waveform having rising and falling portions superposed with the split pulses, so as to provide a resultant drive signal having moderately sloped rising and falling portions by removing a frequency component exceeding the prescribed cut-off frequency (f) from the signal waveform, and to apply the resultant drive signal to inlet ends of the scanning electrodes in the display panel,
• wherein said cut-off frequency (f) is prescribed according to the following formula:
• f=1/(4π(Rt/10)×(Ct/10)),
• wherein Rt denotes a scanning electrode resistance, and Ct denotes a scanning electrode capacitance determined according to the following formula:
• Ct=h×w×εo×ε/(Nc×d),
• wherein h denotes a vertical size of the panel display area;
• w, a horizontal size of the panel display area;
• Nc, the number of the scanning electrodes;
• d, the cell gap;
• εo, a permittivity;
• and ε, a dielectric constant.
