8/Mar/20 I'm watching National Geographic on TV


Good morning world.

Maximus Handsomius here from my forever home, in Cape Breton Island, Nova Scotia, Canada.

In days before the flat screen TV, they had what was called a Cathode Ray.  This was a big glass bulb with a coating on it.  There was what they called "guns" at the back and they would "fire" an image at the front of this big glass bulb.  It was done about 30 odd times a second.  It would fill in each other line.  Then on the second pass, it would fill in the other half.  Back and forth, over and over.

Now the human eye would interpret this as a moving picture across the screen.  This was done with three guns that would again, be projected on the front on the glass bulb.  Blue, Yellow and Red.  This would make up all the colors.

Now, the flat screens, they have different technology.  Typically, either LED or Plasma.  But the colors and brightness of the screens are so much better than what they had in the past.

Now the picture refreshes so fast, that dogs don't notice any flicker on the screen.  

In the past, TV was boring to dogs.  We didn't really watch TV as we would look towards where the sound was being generated.  Think of looking at a bright flashing light that makes noise.  It would get annoying looking at the flashing light.

Now, the TV display is smooth and is no longer flashing.  The TV sets now, refresh at 60 cycles or more.  Faster than what a dog can see across the screen.  Now, we see a picture along with the sounds.

So, now, we can enjoy TV along side our humans.
