Abstract:
1. A liquid crystal display device, comprising: first and second data lines; a first operational amplifier configured to drive said first data line to a potential of a first polarity during a first period, and to drive said second data line to a potential of said first polarity during a second period following said first period; a second operational amplifier configured to drive said second data line to a potential of a second polarity complementary to said first polarity during said first period, and to drive said first data line to a potential of said second polarity during said second period; and a short-circuiting circuit configured to short-circuit said first and second data lines during a short-circuiting period between said first and second periods, wherein drive capabilities of said first and second operational amplifiers are controlled in response to a short-circuit potential of said first and second data lines during said short- circuiting period, wherein said drive capability of said first operational amplifier during said second period is controlled in response to a difference between said short-circuit potential and a potential to which said second data line is driven during said second period, and wherein said drive capability of said second operational amplifier during said second period is controlled in response to a difference between said short-circuit potential and a potential to which said first data line is driven during said second period.
