ABSTRACT:
A display device for information signals which performs highly efficient image display of a standard television signal, a high definition television signal, a progressive scanning television signal or a stereoscopic television signal on the same screen has a first signal input unit applied with the standard television signal, a second signal input unit applied with the high definition television signal, progressive scanning television signal or stereoscopic television signal, a mode designation unit for designating a mode for display of one of the signals, a signal conversion unit including a write unit for writing the first signal, at a frequency thereof, to memories and a read unit for reading the memories at a frequency which is nearly twice that of the first signal, a signal switching unit, a signal processing unit and a deflection switching unit, whereby a first display signal from the signal conversion unit or a second display signal from the second input terminal is selected and image-displayed on the same display unit through a deflection system. Through this, the cost of the device can be reduced, the standard television signal having less scanning lines can be displayed with substantially the same number of scanning lines as that of the high definition television signal, various kinds of disturbances can be eliminated to improve the image quality and a stereoscopic image can also be displayed.
