ABSTRACT:
A semi-wide view display method and device using the same are provided with a semi-wide view function for arbitrarily converting an aspect ratio of a screen in a television. The method includes the steps of setting a display mode according to a user-selected aspect ratio of a television screen; receiving vertical and horizontal blanking pulses, controlling the width of the blanking pulse according to the display mode setting, and outputting the result; generating a television signal which is displayed on the screen and a blanking signal which is not displayed on the screen by inputting the generated blanking pulse; and displaying the television and the blanking signal to thereby control vertical/horizontal over-scanning and vertically lengthen a blanking period, in order to convert the aspect ratio of the displayed image.
