As already said in another thread the technology used for the touchscreen is neither capacitive or resistive. Seems like they use a mesh of IV rays over the screen to detect the presence and movement of fingers, though completely eliminating the need for an extra layer and having no effect on visual quality.
From the website of Neonode:
"zForce™ is the name of Neonode’s proprietary patented touch screen technology.
A selection of advantages with zForce:
Low cost
Low power
100% transparent
Fast capturing of movements
Multi-touch finger support
Support for extended temperature range
No calibration needed
Durable protection (glass)
zForceTM uses a small frame around the display with LEDs and photoreceptors on the opposites sides hidden behind a infrared-transparent bezel.
A controller sequentially pulses the LEDs to create a grid of infrared light beams across the display.
A touch obstructs one or more of the beams which identifies the X and Y coordinates which also give area information. Interpolation combined with analogue signal processing give multiple touch readings and high speed gesture feedback."

If this is the case, wow, very ingenious!
