Better color in TV sets -- and why Indium Acetate plays an important role

  • Indium

  • Go to any TV showroom and look at the amazing TV sets that are on display. If you are old enough to remember the old glass tubes, or even if you grew up with nothing but Flat Panel Displays, you should be absolutely amazed at the color fidelity in the latest generation of displays.

    Of course, pixel resolution and high definition were a huge transformative revolution (imagine what not seeing what's going on in any sports was like?). The other revolution has to do with color: the human eye can see a very precisely defined range of colors. Older TVs (and any other display) are actually not that great at displaying red colors. That's right: If your favorite sports team wears red-colored gear, you mostly see an orange version of the true color ... up until now.

    The big innovation is quantum dots. Tiny (nanoscale-sized) crystals whose size is precisely controlled. When the picture on display calls for red pixels, quantum dots will emit red light that is a better, purer red then the old technology (color phosphors). And there you have it: a larger color space, that allows displays to show pictures that are closer to the real thing than ever before.

    Where does indium come in? The quantum dots contain indium atoms, combined on the atomic scale with phosphor or other atoms. The precursor material to provide the Indium atoms is our company's indium acetate. We make it in different grades to suit various manufacturing needs. Download our product data sheet here.

    And enjoy the next game on your TV!
