Abstract: PURPOSE: A method for adjusting an offset and a gain in an LCD(Liquid Crystal Display) is provided to minimize influence by noise by increasing a measurement number of an outputted data value and adjusting an offset value and a gain value. CONSTITUTION: A black pattern in which noise does not exist is inputted to an ADC(Analog to Digital Converter)(S31). An offset value is initialized(S32). An output value of the ADC is detected and added(S33,S34). The number of detecting and adding processes is set up(S36). The average of the detected values is obtained(S36). The obtained value is determined as an offset value(S37).
