ABSTRACT:
The present invention discloses a screen blanker for a monitor of a computer system, which will automatically clear the data image on the display screen of a monitor of a computer system after the computer has not been operated for a predetermined time period, and the data image which had disappeared will reappear once again on the display screen of the monitor after data is keyed in again by the operator. By this, the display screen of the monitor of the computer system can be protected from getting burned images thereon.
