Render this: LCD screen (light emitting material)

There are a lot of great iPhone renders here in this thread and a lot of good lighting effects.
The original tip, though, was about using a non-light emitting, self-glow, material instead for the iPhone.
Honestly, I don't see the point. What really is to gain about trying a less effective way to achieve a desired result. I hate to say it, but it feels like there is an ulterior motive behind the render tip to draw attention to a feature of a developer's app. IMO, the light emitting textures have proven to be a more realistic result by looking at the posted renders.

Here are a couple of iPhones on a table - one is on and one is off.
i dunno, when my iphone is off, it's just a black screen.

Not sure what the distinction is that you are trying to make. In Kerkythea, the texture can be applied to the radiance (edit material > self illumination > and select bitmap and use the screen texture) function and the texture becomes "self illuminating", it is not a backlit texture.
Here is a completely dark scene with only the screen applied to one surface, self illuminated:
Or am I missing completely what you are trying to get at? Are you trying to achieve a similar effect, without applying self illumination of this type?

Oops - I guess U need to buy one.
But - does it have a lit and non-lit mode?

I think what you showed in your rendering is just what I am talking about. The ability to make something look illuminated, without using or adding any actual light sources to the scene.
@unknownuser said:
New light options including projector lights and manual inputs of light intensities for self luminating sources.
I presume that in the image you showed, we see a reflection of the lit iPhone, but it is not actually a light source??

no, it's just like a standard computer monitor.. on or off and that's it

al: nobody said you cant make it an emitter.....there are many ways of doing this but its the most realistic way of achieving the result. you cant really make something look illuminated without showing its effect on neighbouring surfaces/particles (air/dust etc). correct me if i'm wrong. you are basically trying to make a texture look brighter which isn't convincing.
why are you trying to avoid putting lights behind it? this is largely how screens are illuminated in real life. like a large emitter......again correct me if im wrong...but saturating and brightening a texture wont make it look illuminated.

The texture itself is the source of light, there are no other lights whatsoever in the scene. The reflection on the surface below the screen is actually reflected light off of the ground plane. Kerkthea will create light based on the color of the image used - black, no light; green, green light, etc... Kerkythea does not do "light linking" (yet), where light can be shone on one object of the scene to make it brighter but not affect any other objects. Other render engines can do this though.
One could put lights behind a texture, but I couldn't imagine the difficulty of getting nice, even light out of a large surface by arranging light sources behind it. It would be more involved setup in the render engine as well, you'd have to do something like a multi-layered texture with transparency mapping and translucency set up for the colors.
Another example, this time the blacks are not completely black so they do emit some light. A quick "plasma TV".

twilight easy 09, 24 minutes
planning to buy the real version soon -
Mine first try ;D

Just got a few minutes - eventually - to give this challenge a go.
-
My quick try,
exported to MODO 401 for rendering
-
Ha Ha. Great render Rob.

Just join, so just post....a quickie for the shine..but not the emitter..oops!

Iphone sucks Android rules!!
SUCK IT!!!!

Hi to everyone, i would like to share my attempt.
Rendered with Vray for SU, SU lines overlay, some level, color correction and DOF in PP.
No light, only the emissive material of the phone.

quick question with the LCD screens. I'm working on a LCD TV and I wanted to know if there is a way to in/decrease the amount light the image (screen material) emits without affecting the actual image's appearance. What I'm getting right now is a decent light level being emitted but the image is getting washed out. Any ideas?

What render app are you using?

One trick you could try is to place an invisible, second face in front of the visible face. Make the second face the light - diffuse so the light only goes up - and then adjust the intensity of the invisible face get the lighting effect you want, without having it effect the illumination of the visible face.
If you are using IRender nXt, you would illuminate the visible face with "self glow", - a setting which make it seem illuminated without emitting illumination, and make the invisible face a diffuse light. By placing the two faces in separate lighting channels, then you can use the post-processing image editor to quickly adjust the lighting intensities and effects of the two faces without having to re-render ay of the scene.
