      You want mind blowing, try putting on polarized sunglasses while watching LCD display and tilt your head 90 degrees. This is why pilots don't (usually) use polarized sunglassed. The displays in the cockpit are LCD's and the sunglasses may sometimes hinder their ability to see them.

    I used to work for a company that made LCD's and it was the best job I ever had, because I am a nerd and found fun and interesting. Unfortunately the place went under or rather over seas (the plant closed and was moved to Japan) , a lot of people lost their jobs, What a shame. But people don't want to spend big bucks for products with LCD 's , we 'Mericans want to go to Walmart and and buy a super sized TV for cheap . We weren't that advanced, we only made small glass displays for things like gas station pumps , but still it very interesting to learn the science behind how they work. Thanks for the video. I'm an artist and I've always thought about how LCD's might be used to make some kind of art. It's working with color and light, which nerdy artists like me just love to play with.

  • @Tattlebot
    @Tattlebot Рік тому

    Note that your mockup of the TN voltage on state is incorrect. The LC directors orient toward the electrodes, breaking the twist. What you depicted was a sort of in-plane switch. TN LC is positive dielectric anisotropic, so you would have to move the ends of the LC toward the polarizer, sort of like a fallen stack of books.

      I get it, but in lit offices, working on bright imagery like word documents, CRT can reach barely above newspaper perceptual contrast, about 20:1. LCD retains very high contrast, so colour saturation is much more stable across ambient light levels, at the cost of poor saturation of very dark shades.
      A good IPS panel will have even better viewing angles than CRT, due to lack of thick reinforcing glass. Then there is also energy savings in producing and using LCD.
