<P>PROBLEM TO BE SOLVED: To correct variance in luminance of a display panel at high speed. <P>SOLUTION: A conversion data determining method of the display panel is characterized in having a 1st measurement step for finding a 1st driving current of a light emitting element of the display panel when the capacitor of a pixel other than a measured pixel is not completely discharged, a charging step for charging the capacitor of the measured pixel with an analog voltage, a 2nd measurement step for measuring a 2nd driving current of the light emitting element of the display panel when the capacitor of the measured pixel is charged to the analog voltage, a driving current calculation step for finding the driving current of the measured pixel from the difference between the 1st and 2nd driving currents, and a data calculation step for finding conversion data based upon the driving current. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
