Abstract

PURPOSE:To make uniform the luminous amount to gradation data having an identical value by lighting sequentially light emitting elements by means of a changeover switch, detecting a current value at that time by means of a detecting section, storing the value in a luminous amount correcting memory and using the value as a correcting value in case of display state. CONSTITUTION:The changeover switch 64 is thrown to the position shown in broken lines, light emitting elements 41 are lighted sequentially and a current detecting signal S2 is detected from a current detecting section 50. Then, after the signal is processed by a data processing section 62, the data is stored in the luminous amount correction memory 63. The switch 64 is thrown to the position in solid lines by an operating section 61, a gradation data D1 is read from a display memory 17 and a luminous amount correction data D2 is read from the luminous amount correction memory 63. Further, the operation of D1-D2 or D1+D2 is performed by an accumulator 65 in response to the value of the luminous correcting data D2 and the result is applied to a display control circuit 20. As a result, an element being too dark to the same power is lighted long and an element being too bright is limited, allowing to make uniform the luminous amount to a prescribed gradation data.
