I’m Ken Kuwako, your Science Trainer. Every day is an experiment.<\/strong><\/span><\/p>\n

Did you know that the screen you’re looking at right now, both the white areas and the black ones, is actually made from combinations of just three colors of light? This time, I took a closer look at the secret of the \u201cthree primary colors of light\u201d hidden inside an everyday screen using a digital microscope I bought as a gift for my child.<\/p>\n

A Budget Digital Microscope That Packs a Punch<\/h3>\n

The microscope I bought this time is the Koolertron digital microscope<\/a>. I originally chose it as a gift for my child, but I quickly came to appreciate the fact that, because it is reasonably priced, I don’t have to worry too much about it being handled a little roughly. At the same time, it has more than enough performance for everyday observations, which is a big plus. Since it has its own screen, we can look at the same magnified image together, making it a great tool for exploring science with kids.<\/p>\n

What You Can See When You Magnify an iPad Screen<\/h3>\n

The first thing I tried with this camera was taking a closer look at an iPad’s LCD screen. And there it was: clear as day. Every color on the screen is created by combining three colors of light known as RGB<\/b>.<\/p>\n
