Tuesday Tech Tips

Just as we are getting the old style CRT (cathode Ray Tube) monitors and TVs out of our houses and offices, finally, and the LCD screens are common place and very cost effective, the next wave of display technology is rolling out: LED screens.

Samsung has introduced a line of LED TVs, and they are a premium price, but not outrageously expensive. Like the genius of the MacBook Air, these use LEDs as the back light, saving energy and weight and space.

Sony has the next technology in the hopper, too: Organic LED TVs/displays.

Now LG is entering the fray, with plans for a 15″ TV coming to the commercial market soon.

The benefit? OLEDs produce their own lighting. No need for the fluorescent tubes in the back, with the increase in form factor to house them, and the extra electical and electronics to power/control them. Net result: Thinner displays. Side benefit? Lighter weight. Now there’s not the issues with the wall mount style where you can’t really get into the structure of the wall for an anchor point in a stud to save yourself from coming home to the carnage of a TV smashed in the middle of the family room.

Other benefits? OLEDs, can use a single light tube (I don’t recall the proper term) to display the red, green and blue signal needed to produce a “pixel” (picture element) on the screen. Right now, we are used to seeing a pixel that actually is comprised of three separate parts, positioned together to dispaly the correct colors. Because of this, we have been limited to the 72-75 dots per inch resolution on a computer display. With the “stacking” of the LEDs, the resolution will tripple, meaning pictures that come very much closer to looking like a high quality photograph.

Better yet? They are produced on a flexible plastic “substrate” and are bendable (not foldable). consider the application of being able to put a display on a non-flat, or even flexible surface (think clothing) for all sorts of purposes….Wow, huh?

Maybe the best benefit? These displays use less and less energy. That’s great, because plasma uses 5X the energy of a CRT TV. If we all went that route, we’d really be using up the power grid output.
