Abstract
PURPOSE: To obtain a display device whose luminance can be adjusted by providing a means instructing luminance adjustment, a means specifying the luminance, a means deciding the set data of the luminance in accordance with their outputs and a means deciding the luminance based on the set data. CONSTITUTION: The luminance adjustment is instructed by depressing the CODE key CK of a keyboard 1. The luminance is specified by number keys 1-4, and the set data E0 -E3 of the luminance are decided in accordance with the output. The luminance of a cold cathode tube 6 is decided by that the input voltage V for an inverter 5 alternates and is made as the input voltage for the cold cathode tube 6 based on the set data decided. The display device having the cold cathode tube whose luminance is freely easily changed and adjusted so as to make an operator feel it adequate comparing with the display device of the cold cathode tube whose luminance can not be adjusted as in the conventional manner is obtained.
