BLACK & WHITE TUBE PHOSPHOR APPLICATION
Posted by STEVE MYCIUNKA on
Here we have a nice photograph taken at Mullards in 1952 of Sebastian Firkle who is laying the luminescent screen in a Mullard picture tube. The screen phosphor was suspended in a liquid carrier and introduced into the envelope. After settling, the supernatant liquid was carefully decanted off leaving an even distribution of phosphor which was then dried under a gentle stream of cold air.
