I also have 2 TVs both with LED and LCD displays, and after several hours my 32" LED TV gets hot while my 37" LCD TV stays cool as if it was turned off and my LED TV has some burn in spots.
Personally I'm glad I got an Amoled one.

my phones amoled but my m8s is slcd dident think to much of the slcd tbh the black in apps list looked grey and the colours just dident look as vibrant.
agreed
samsung really screwed htc on supply of the amoled screens

both are great, and there is very little difference in image quality.
Amoled is slightly more dynamic and the colours are a bit brighter, slcd is slightly crisper and the colours more realistic so Its down to personal preference.
Amoled has been proven to use less power though despite HTC saying the opposite when they introduced the slcd replacements.
but... HTC would have prefered to use Amoled in all Desires if possible, but the shortage in Amoled screens forced them to use slcd ones.

Is there a way to tell which display your phone has ???
I prefer AMOLED. AMOLED shows black as black while S-LCD shows something grayish.
On the otherhand, the density seems to be better on S-LCD.
By the way, S-LCD does not mean Super LCD.
S-LCD is a just a brand name of a product line of TFT LCDs. (Google S-LCD Corporation).
I had the Nexus one with the Amoled screen and after three weeks the screen showed signs of screen burn in and there was no way to fix it or stop it, so if you do not care about burn in then the Amoled is for you, personally i think Amoled is junk and there are many different threads that can be found by Google that support the burn in problem of the Amoled screens, I will take the Slcd any time over Amoled, infact Amoled is a deal breaker for me.
Slcd means Sony LCD brand, they make the Slcd for HTC!!!!!!
