A picture display apparatus for displaying a picture in response to inputted
picture
signals of an arbitrary format. The apparatus includes a picture display unit having
an arranged matrix of dots for picture display, a picture display unit drive for
converting inputted picture signals into display picture signals adapted for display
on the picture display unit and generating drive timing signals for driving the
picture display unit, the picture display unit driver including a picture memory
for storing picture signals inputted into the picture memory, a display position
detector for detecting a picture display position on the picture display unit based
on the display picture signals and the drive timing signals, and a display position
controller for controlling a timing of admission of the inputted picture signals
to the picture memory of the picture display unit driver, based on the detected
display position data from the display position detector. The picture display unit,
the picture display unit driver, the display position detector and the display
position controller are integrated to form the picture display apparatus for receiving
the inputted picture signals of an arbitrary format.
