JLB 1927 CRT

[Harry Dalek]

Hi i came across this photo of JLB playing around with a crt in 1927 .

I love the crt but where is the phosphor ? leads me to wonder if it was a projection television if so was that another first ?

I think the phosphor was on a screen in the middle of the large bulb....he did some corrugated plates for colour and 3d too!

I think this photo was much later, say 1935. I see tubes that are younger than from 1927. In 1927 the radio lamps had a different form.

Oh ok i was not sure on that ,i love the crt your right it does look like a big light globe !

Yes i was amazing what he did he may not of invented the television idea but he invented or tried every form of television ....reading during the war he was doing slow scan tv fax as well.
