All LED's (OLEDs) can sense light

This type of technology should work fine on mobile phones, as all LEDs are able to "sense" light...both ambient as well as its own light reflected back into it.

Each pixel is effectively its own independent sensor, so the technology could also be multi-touch. Infact, it should have the complete raster outline of the object touching it, so it would be even better than capacitance.

This is a very strange and misunderstood property...if you are interested, you can do some research on theory and a few implementations of this.
