Led TV

Hello,
 
I am electrically sensitive and will buying a new TV shortly.  A  friend
said I must but a LED and not a LCD.  Please explain the  differences and why
LED is better.
 
 
Thank you.

I don't think LED TV's are necessarily better than LCD TV's, at least
from a "bad reaction" standpoint.  You should definitely look at them
in the showroom and judge for yourself.

There is something about LED light than I sometimes find "painful"
to look at.  This is not an ES reaction, but I think it is something
about the spectrum of light that is being emitted.  I quickly get
eye pain from some LED sources, and that has included certain
LED-backlight laptop computers.

There was a time that I thought LED would be "the" solution to all
of the florescent lights around.  Now I'm beginning to think that
LED lighting will be even worse... :-(

Thank you Marc.  For some reason my friend thinks LED  better but everybody
is different.
 
My computer  has a LCD screen and I have not problem with  that.

I doubt it is the color spectrum causing problems
(not impossible perhaps, but our visual system is
good at adapting to different spectra caused by different
light sources)--
but the fast switching time of LED's could be a problem.
There might be also an issue of the timing of different
colors, which causes rainbows on many projectors
when you move your eyes.

Estelle,

I find a 720 LCD is better for us w ES.  

Haven't tried LED.

Kathy, thank you for that information. It seems that most feel  that LCD is
superior to LED so I'll leave it at that.  
 
A huge problem for me is the fumes that come from new  electrical  things.
I don't know how I'll deal with that yet.

Even though I have a 1080p LCD HDTV, I find that the resolution
of the input signal can make a difference.  That is, feeding the
set a 720p or 1080i input signal is easier to tolerate than
feeding it a 1080p input signal.

But yes, I image that a 720p resolution TV set might be
easier to tolerate than a 1080p TV set, all other things
being equal.

There's a lot of variation in the amount of fumes coming out of different
pieces of electronics.  So probably the best way to deal with something
like that is to return the item and get something made by a different
manufacturer.

Hi,

As Marc said, LED TVs are not always better from a symptoms standpoint.  But whether or not a LED TV is better than its CCFL counterpart can vary from brand to brand - or from model to model.  Whether or not a LED TV is better depends on what specific TV (brand, model) you're comparing it to.

I wish there was a set-in-stone rule that certain types of TVs are better than others - or certain types of computers are more tolerable than others (just to name a couple of appliances) - but unfortunately, things don't seem to be that straightforward.  From my experience, at least - settling on what device is most tolerable for you can be very trial-and-error - involving a number of store visits, returns (check that return-policy), etc..

I have personally had four different "flat screen" TVs in my bedroom over the past three months; well, actually five - when you count when I had to exchange a defective set for one that was in better condition.  They either didn't work out as I had hoped - or I was trying to see if a different model would be better on my e.s..  It seems that I've "settled" on a Samsung LED TV - a 26-inch (all of the TVs I've tried have been 26").  The specific model, in case you're interested - is UN26D4003.

Of the TVs I tried - this model has offered the best combination of tolerability and quality - at least for me.  The other 3 TVs I tried were CCFL-backlit - so in this situation, a LED TV happened to be the winner.

One advantage that many LED TVs have over their CCFL counterparts is that they run cooler - the LED backlights don't get as warm/hot as CCFL backlights - so the TV emits less heat.  This difference can be important for smaller rooms with poor air-circulation (like my bedroom) - and/or for larger TVs.  (If I had chosen a 22" model - the heat differences might not be as significant.)  That was one of the major problems with the first LCD TV I tried - a Toshiba 26C100U.  Since I had to keep the backlight of that TV at the maximum level to avoid bothersome emf frequencies - that TV generated a lot of heat - and it kind-of made my bedroom an oven.  

But not all LCD TVs get as hot as the Toshiba.  A Sharp LC26SB24U felt noticeably warmer than the Samsung LED TV - but it didn't heat up my bedroom like the Toshiba.  And I don't think I "felt" it as much as I (sometimes) feel the Samsung LED.  But the picture-quality was overall poor when compared to the Toshiba and Samsung TVs - the quality was such that I didn't think it would be acceptable over the long-term.

Finally - I tried a Samsung CCFL model - the Samsung LN26D450. I thought it was possible that I would "feel" that TV less.  That didn't turn out to be the case.  The picture quality was pretty awesome - a little better than the LED TV (IMO) - but it is a strong emitter of radio-frequency emf.  When I held my portable AM radio to the TV - it produced strong noises some 3 or 4 feet from the screen.  (The LED doesn't provoke that response.)  I guess that explains the "vague" symptoms I had - i.e. fatigue (that would come and go), an "unsettled" feeling in the head, poorer sleep quality.

So it is the Samsung LED for me.  Sometimes - when I turn off and/or unplug the TV - I feel more of a positive-difference than I would like (I guess that means that the TV is - to some degree - emitting frequencies that I'm sensitive to.).  But it's been better for my e.s. than a lot of TVs have been or would be.

So that's my journey - my own "trial and error" process.  Maybe there is something in this "saga" that you would find helpful.  Good luck. :)

Btw, what size TV are you interested in?  


*Oh - and when I talk about picture quality - I'm talking about standard-definition.  We don't have HDTV (at least not yet).  But with the type of problems that the Sharp TV had...it's possible that the same problems with picture quality would exist even in HD.

Good point.  I have smelled a "plastic odor" coming from these TVs - but I'm unsure whether the smell is actually coming from somewhere on or within the TV itself, or if it's coming from the plastic "shrinkwrap"-like material that is placed on their outer frames for shipment (and is easily peeled off).  I've kept this plastic covering on the frames as I'm "testing" them - since I've been unsure about whether or not I'm keeping them.

I don't think the smell is actually bothering me that much - although that can be hard to determine since the e.m.r. issue can overshadow or "mask" it.  

I thought Samsung was one of those companies that supposedly kept hazardous substances to a minimum - I've heard something along these lines (for what it's worth).

Oh yeah! Did a test run with it 12v led today (really shouldn't have considering I still haven't found my idle prob), connected direct to bat with a simple switch on led flood light the neg lead. I think I'm just going drill out holes in my fuse box and fit the LEDs through, the thing's so light I'm probably just going to end up taping it to the underside.

I checked its readings with led strip lights that of my multimeter simultaneously, it's indicator color patterns and chart match up perfectly with my digi multimeter. Thanks for the idea.
