Hanvon unveiled new touch technology called ERT (Electromagnetic Resonance Touch). ERT can sense both pen input and finger touch - and is placed beneath the display panel and not above it like normal touch layers. It works by adding several capacitors to a normal digitizer touch sensor.
Hanvon plans to commercialize this technology in its E Ink e-readers (for the Chinese market) by 2H 2011, but it says it is also applicable to OLEDs and LCD display.
