<P>PROBLEM TO BE SOLVED: To obtain a device of adjusting color balance and an electronic apparatus in which color balance is automatically adjusted according to the variation in luminance of an organic electro luminescence (EL) element due to an elapse of time. <P>SOLUTION: Electric currents which allow a red, a green and a blue organic EL elements emit light, and luminance ratio of red, green and blue for adjusting the color balance are stored in a storage part 40, a control part 60 periodically measures the luminance of red of a display part 10 with the electric current for red by using a luminance measurement part 20, and the color balance is so adjusted that the luminance ratio of three colors coincide with the luminance ratio stored in the storage part 40 by adjusting respective luminance by varying the electric currents for green and blue by taking the luminance of red as a standard. <P>COPYRIGHT: (C)2004,JPO |
