DRIVING CIRCUIT FOR DISPLAY APPARATUS, AND METHOD FOR CONTROLLING SAME |
摘要 |
To obtain an amplifier circuit capable of realizing low power consumption and high-precision output. A controlling unit controls each switch of an offset correction circuit to select one capacitor associated with a voltage level of an input signal selected by an input signal selection unit, have an offset voltage of an operational amplifier generated according to the voltage level of the input signal stored by the selected capacitor, and correct an output of the operational amplifier by using the offset voltage held by the selected capacitor.
