ABSTRACT:
The device of this invention controls a cathode ray tube (CRT) in order to display desired images on a selected region of the screen. Locations on the screen are identified by horizontal and vertical addresses. The device comprises means for storing information to be displayed on the screen of the cathode ray tube and a control means. The control means selects information for display and generates a display control signal for controlling the cathode ray tube. The display control signal causes the cathode ray tube to display the selected information and also indicates a predetermined vertical or horizontal address. When the display control signal indicates a horizontal address, the control means displays selected information only in the region of the screen above or below the horizontal address and not in the remainder of the screen. When the display control signal indicates a vertical address, the control means displays selected information only in the region of the screen to the left or the right of the vertical address and not in the remainder of the screen.
