<P>PROBLEM TO BE SOLVED: To provide a driving current value adjusting circuit for an organic EL driving circuit, by which brightness variations in a display screen among apparatus such as a portable telephone or a PHS is reduced and production efficiency is improved. <P>SOLUTION: A switching circuit receives data from a nonvolatile memory, to which data are written, and conducts ON/OFF operations and then, driving currents of terminal pins are respectively adjusted in accordance with the data. Therefore, the brightness variations is reduced by writing the data, which are required for the luminance adjustment to correct luminance dispersion or luminance irregularity, into the memory. <P>COPYRIGHT: (C)2004,JPO |
