段を設けたことを特徴とするＣＲＴ装置。A flag that is started by a timer and stores whether or not there is a change in the cathode ray tube display signal from the CPU or the keyboard, a counter that stores when the display signal does not change, and a brightness state of the cathode ray tube. A memory comprising a flag that indicates that the CRT display signal is not changed for a certain period of time according to the state of this memory, and if the CRT display signal is not changed for a certain period of time, the brightness of the CRT is lowered, and if the CRT display signal is changed again in a reduced brightness state; The CRT device is characterized in that it is provided with means for restoring the brightness of the cathode ray tube to its original state.
