ABSTRACT:
A display apparatus, which is connected with a control device, receives from the control device synchronization (sync) signals and a video signal in synchronism with the sync signals having a prescribed display area. The display apparatus generates a deflection signal on the basis of the sync signals in a deflection signal generating circuit to scan a CRT. The display apparatus adds additional video signal outside of the display area of the video signal on the basis of the sync signals in a video signal adding circuit so that the display area for the video signal is expanded, and supply the video signal thus formed to the CRT. Thus, in the display apparatus, a white background area can be added outside of the display area in the CRT.
