发明名称 CIRCUIT ET PROCEDE D'ATTAQUE D'UN DISPOSITIF D'AFFICHAGE A CRISTAUX LIQUIDES
摘要 <p>A circuit for driving a liquid crystal display device, as embodied, includes: a gray level voltage generator for generating a plurality of gray level voltages; and an intermediate gray level voltage generator for receiving a first gray level voltage and a second gray level voltage among the plurality of gray level voltages and for selectively outputting one of the first gray level voltage and a third gray level voltage through a plurality of capacitors, a value of the third gray level voltage being between the first and second gray level voltage and set by the plurality of capacitors, the intermediate gray level voltage generator including: an operational amplifier for pre-charging the plurality of capacitors using a current outputted from the operational amplifier and for selectively outputting one of the first gray level voltage and the third gray level voltage.</p>
