Toward Micro-Diode Display Panels?

Posted by Cliff on from the large-two-dimensional-LED-arrays dept.

VernonNemitz asks: "Light-Emitting Diodes (LEDs) have been around for decades, and they come in all colors. Here are the basic principles behind their operation, information on what's currently in production , and other practical info. Now, you would think it obvious that video displays should be made from LEDs, to take on the various competitors. Certainly this has been done on a large scale, and I am not the first to be interested in LED display technology for home viewing. The apparent goal of silicon LEDs these days seems to be tied up with optical communications between circuits, have they forgotten the possibility of making high-resolution display panels?"

"Achieving a good image will require smaller pixels, and now I have a better understanding of what has been holding it up, so would like to share what I found out. Basically, unlike a lot of electronic technology, LEDs are mostly -not- made from silicon. So, while silicon diodes are common, and large arrays of them are also made (for sensors), LEDs are not easy to incorporate into standard integrated-circuit manufacturing. Nevertheless, researchers have been pursuing and steadily making progress toward integrating silicon-based LEDs. Even whole arrays, 'suitable for large two-dimensional areas', of silicon laser LEDs have been made, as far back as three years ago."

  1. Being my area of research . . . by nil5 · · Score: 4, Funny

    I can say that this technology is at LEAST 25 years away due to the lack of precision in nanostructure topology lithographic processes. The author seems to be ignorant of a few of the fundamental laws of nanotech, namely that: 1) Maxwell's equations must be obeyed in light of quantum gravity. Yes, quantum gravity is CRUCIAL to the process. This prevents the inadvertent bonding of junction pairs and 2) The superposition principle does NOT apply to these non-inertial frames of reference! Trust me, this technology is pretty much canned until we can solve a few engineering problems in the litho. area.

  2. I shirk LED's by niko9 · · Score: 0, Funny

    Between the skin cancer and the glare off my tin foil hat..er I feel a song coming on...

    Roses are red
    Violets are blue
    I'm a schizophrenic
    And so am I.

    Back to the LED's, I always apply a generous of SPF 45 when I see one shining my way.

    Of course we'll still be bitching. We're American.
