<p>PURPOSE:To allow the correction of the fluctuation in display by providing a means for generating a carry signal when an LCD panel is divided and an analog switch for changing over the gate-on voltage and gate-off voltage of a TFT. CONSTITUTION:A driver 1 outputs the carry signal for selecting the upper half of the LCD when the LCD 2 displays the upper half part. The bias voltages VGon1, VGoff1 determined by a bias 9 for the gate-on voltage and a bias 10 for gate-off voltage are then selected and pulse waveforms are formed by the upper and lower levels. These waveforms are outputted from a gate-on voltage output terminal 6 and a gate-off voltage output terminal 7. The driver 1 outputs the carry signal for selecting the lower half part of the LCD when the LCD 2 displays the lower half part. The bias voltages VGon2, VGoff2 determined by the bias 9 for the gate-on voltage and the bias 10 for the gate-off voltage and the pulse waveforms are formed by the upper and lower levels thereof. These waveforms are outputted at respective timings.</p> |
