<P>PROBLEM TO BE SOLVED: To suppress variance in luminance by making variance in mobility correction time needed for mobility correcting operation relatively small by extending the mobility correction time, and to set the pulse width of a write pulse to an optimum pulse width. <P>SOLUTION: Before the voltage value of an input signal voltage to be sampled is made high in steps and a voltage signal Vsig having a desired voltage value is written, precharging wherein a precharge voltage Vpre having a voltage value smaller than the voltage signal Vsig is written and preapplied to the gate of a drive transistor is carried out to thereby make the gate-source voltage of the drive transistor during the writing of the signal voltage Vsig small, thereby extending the mobility correction time needed for the mobility correcting operation. <P>COPYRIGHT: (C)2008,JPO&INPIT |
