We’ve been talking about colour tv in class and I found a few items you might want to look at. First of all, the website I used in class is available here and there is further information on combining colours here.

There is also a helpful animation of the shadow mask that stops the three electron beams from reaching the wrong phosphor dots.

S3 - How do you get a picture on a TV screen? September 4, 2007

Posted by mrmackenzie in : Telecommunications , add a comment

We’ve been looking at the demonstration picture tubes in class. Now we need to find out how to get from a single bright spot on the screen to having a picture covering the whole screen. Here is a link to the website I will be using in class to help explain how a picture is produced.
