LEVEL CONVERSION CIRCUIT, MULTIVALUED OUTPUT DIFFERENTIAL AMPLIFIER AND DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To highly accurately correct an output offset of a multivalued output differential amplification circuit by a capacitance storage method.SOLUTION: A level conversion circuit includes: the multivalued output differential amplification circuit having an inverting input section, an output section and two or more non-inverting input sections; a plurality of as many capacitors as the non-inverting input sections disposed in correspondence with the non-inverting input sections and connected to the inverting input section at one end; a first switching section for switching connection destinations of the other ends of the plurality of capacitors between the corresponding non-inverting input sections and the output section; and a second switching section for switching a connection between the inverting input section and the output section.
