Abstract: Complete or perfect display of digital image information on VGA interface display involved in
construct of timing signal and image data DA converting. A design sc eme of VGA display interface is
presented. M et od of digital image data DA converting and output to VGA interface display is given,
w ic includes ardw are design, control of video DA converter, construct of VGA timing signal by FP-
GA. T w o design met ods and tw o typical applications one is to display result of image processing, anot er
is to aid for fore terminal video design, are given. T e sc eme can be w idely applied in instrumentation,
digital video systems, ig resolution color grap ics, video signal reconstruction.
