Self lit pixels
« on: June 06, 2020, 01:17:06 AM »
Curiosity post.

Just saw an advert on TV from one of our superstores here (you know... the ones that sell everything from beds, floor coverings and furniture to cameras, computers, fridges and electric toothbrushes - but finding a toilet is difficult, and when you do, you have to walk miles).

It was for an OLED TV with 'the power of self-lit pixels'.

Ok.... I assume the screen is made of zillions of tiny SMD leds (SMD in this case must mean Sub Microscopic Devices!!) which light up, therefore negating the need for backlighting.  :hmmm:

Oh, and these stores aren't so bad.... while your wife is looking at garden furniture or even vacuum cleaners, you can rest up on the settees in the furniture section  :D

That's basically how OLED works, AFAIU: https://en.wikipedia.org/wiki/OLED

Also it's organic, so environmentally friendly :D :P

coincidentally i  have just read this
 
Quote
A new type of display panel using a special "liquidcrystal" material is currently under develop-ment. Words or other information appear on it when a low voltage is supplied by wires which are concealed in this photograph. Immediate practical uses are likely to be data readouts for control panels, animated labelling for keyboards,and see-through map displays which pilots and drivers can read "head -up" without losing sight of the view ahead. One day, "liquid crystals"might provide television screens thin enough to hang on a wall(Marconi)

So basically, this 'self lit pixels' is just a load of suck-you-in advertising crap. It was there all the time.

Damn, I thought it was some new infinite energy source. :(

Is that possible, or are you pushing the envelope?  ???

Unfortunately it bends the law of conservation of energy.
The years have been good to me, it was the weekends that did the damage.

It's an electronic perpetual motion machine. But to reduce the friction you have to polish the LED's by hand.  :D

Actually in my defense, I was thinking of the ambient light falling on the screen powering the leds.

But that's just as daft when I think about it.

Serves me right for engaging the keyboard before putting brain in gear  ;D
