LSI Device including a liquid crystal display drive

In a circuit for driving a liquid crystal display, said liquid crystal display including segment electrodes and a counter electrode, said circuit including a segment electrode selection signal generator for driving selected ones of said segment electrodes of said liquid crystal display, a liquid crystal enable voltage generator for developing a plurality of voltages to drive said segment electrode selection signal generator and for developing a further output signal, a counter electrode selection signal generator responsive to said further output signal for developing a voltage waveform and applying said voltage waveform to said counter electrode, and control means for developing a control signal and for developing driving signals for driving said liquid crystal enable voltage generator and said counter electrode selection signal generator, the improvement comprising:

• a plurality of bleeder resistors for generating said plurality of voltages from said enable voltage generator;
• open-circuiting means responsive to said control signal from said control means and connected in series with said bleeder resistors for open-circuiting a current path through said bleeder resistors and for constraining the plurality of voltages to a substantially identical level;
• and
• clamping means responsive to said control signal from said control means for containing the voltage waveform being applied to said counter electrode by said counter electrode selection signal generation to a voltage which is substantially equal to said substantially identical level.
