And the distance here is much smaller then with other monitors or TVs. I've seen my kid playing with thisphone at the distance 6.5" from his eyes. I watch movies at 8.5" with reading glasses. Do you realize what that means? It means as if we sit in front of 40-60" TV.
But it is very possible the UV level is almost zero here if Samsung cared or voltage is small. So we need to check first, it's by the way easy as 2x2. Each school kid can do that, just take standard spectrometer

1 it is of rezidual values,
2 the intensity decreases with the distance.
3 not all UV are dangerous, those close to the visible spectrum (as it MIGHT be the case here) pose no risk.
Anyway UV it's everywere when the sun shines:).
[deleted post]The point Anonymous rises about safety is valid. It very possible that they emit something in UV.
I will look with the spectrometer same time soon what we get from SAMOLED in UV range.
As we know usually Swedish standard is very strict on all kinds of radiation from monitors. Will see if they will raise this question at some point.
But the solution here is probably easy as adding UV absorbing protection materials into glass.
Do anyone knows what is max voltage applied on subpixel? That will be max energy of the photons the screen will be able to emit.

Vibrant doesn't have front facing camera and gsmarena doesn't correct the specs in order to misinform the buyers. The same for Captivate, Captivate doesn't have front facing camera and its specs on gsmarena wrongly state that it has. It is no error, it is on purpose to promote these buggy galaxies.

More of a question than a opinion.. How do I copy my contacts to my Vibrant? My sim card doesn't allow me to attach pictures, or ringtones to my contacts and its driving me NUTS!!!! Please help!

Hey guys does anyone know where i can purchase this phone for the best price in the U.S that is? Thanks for your answers in advance!!
AMOLED is definitely worse than a good TFT - ISP with LED back lit.
An important factor that has to be consider for this Super AMOLED is that the light directly beams into eyes from its source which is OLEDs.
All natural vision of human eyes is when the light comes from reflections of light, generated by sun or lamps, over objects: the photon beams don't directly get from source into eyes; also the beam of phones is not reflected as you may think: you don't get back through reflection the original photons from source; the phones are not as ping-pong balls cast back by objects which they hit; the beam is absorbed by objects, converted in energy and the objects emit other photons back in a sub spectrum of the original beam, lower intensity and broader uniformity over object surface thus giving color to objects and thus protecting the eyes from artificial light that maybe dangerous for human retina when comes from artificial powerful punctiform sources. The LED back lit from TFT is diffused over a white panel then by reflection passes though liquid crystals and get into eye so it is a reflected light, not the original light. OLED like CRT colored phosphors or plasma's pixels directly beam the light into eyes thus you are not protected from X-rays and ultraviolet emissions (UV radiation) and high energy photons which make lesions in organic tissue.
So, TFT displays are safer for health than AMOLED and CRT and plasma displays.

They work under the same principals as LCDs except they use organic diodes to produce light which have off states to produce vibrant blacks and save battery power since each black pixel in a picture with black colurs is in off state or turned off pixel (No power used), and each pixel produces it's own light, a backlight is included to boost the already existing lighting with an option to turn it off...
these are the qualities tht make AMOLEd desireable vibrant colours and low power usage...
CRTs use an electron gun to fire electrons at the screen tht react with the phospherous coated front screen to produce light..
c'mon they teach this in physics class high school to Uni... u got to be kidding me with tht loong a** answer tht makes no sense!!!
LCDs OLEDs AMOLEDs are based on crystal manipulation technology and are safe for ur eyes
CRTs are minature partical accelerators tht smash electrons to a screen convering their energy to light energy by reacting with the phospherous coatings... n they aren't tht great for ur eyes a below 50Hz CRT can cause Nausea n headaches!!!
Hope u leart something...
i have the samsung vibrant and i love it. i found it cheaper than the iphone 4 and i say that they rate about the same.... but i cant say the iphone for might have a little more advantages, such as more features, etc. but over all the phone is great phone
Power consumption - most of web pages have white background:
While an OLED will consume around 40% of the power of an LCD displaying an image which is primarily black, for the majority of images it will consume 60–80% of the power of an LCD - however it can use over three times as much power to display an image with a white background such as a document or website. This can lead to disappointing real-world battery life in mobile devices.
