Can somebody describe the scanning mechanism of the large screen 
projection TV?  In the ordinary cathode ray tube TV the (interlace)
scanning is done by the deflection plates.  I wonder how it is done
in projection TV.  Usually it is quite difficult to steer light beam
electrically.

---Thanks in advance.
