Television Shows Full Size Images (Jul, 1931)

Television Shows Full Size Images
MOVING television images on a screen 10 feet square, produced beautifully clear, perfectly defined, and possessing the illusion of depth, is the latest and most amazing step in the advance of television art. This new development, accomplished by Mr. U. A. Sanabria, a Chicago television expert, enables a large crowd of spectators to view a radio performance, and heralds the day of “television theatres.” Full size images are made possible chiefly by development of a new neon arc tube and a special scanning disk.

    Aside from saying how perfectly clear these images are supposed to be this article really doesn’t say much as to how it’s supposed to work. Pictures of neon arc tubes and the mention of special scanning disks don’t tell us anything.

    That’s quite remarkable! I had studied the early scanning disc TV’s, but never heard of this improvement until now. The early sets had terriblely poor resolution as they could only have 60(I think) holes in the disc which meant 60 lines instead of the 525 lines the standard we had prior to HDTV which has even more resoluton. What made the low res even tolerable was the fact that the early sets were only about 5 or six inches in size. Even then, the image was very fuzzy and orange the color of the neon tube that was used. I would be amazed if even with the improvements outlined in the patent could make an acceptable picture on a ten foot screen. BTW, the Google Patent is another example of the unlimited possibilities of the internet! Thanks, Firebrand.

    Oh: interlaced scanning was invented by Ulises Sanabria for the Nipkow disk, before it was used in electronic television!
