ABSTRACT:
The display apparatus has a band-pass filter for limiting an input video signal to a bandwidth equal to or narrower than half of a frequency band which is calculated from the number of display elements along the horizontal direction of a screen. Further a computing circuit computes vertical interpolation video data in order to correct for the difference between the number of display elements along the vertical direction and the number of scanning lines along the vertical direction of the input video signal. Even if various kinds of video signals are input, the display apparatus displays images corresponding to the video signals, by controlling the brightness of display elements arranged in a matrix form.
