ABSTRACT:
Disclosed is a display device for detecting working load of a CPU which includes a resistor having a low resistance connected in series between a power supply and the CPU. The voltage drop across the resistor is amplified by a differential amplifier. The amplified voltage is converted into digital signal by means of an A/D converter. A plurality of LEDs are driven by the digital signal to responsively show the working load state of the CPU.
