Strapped to the back of the LCD is a small PCB housing a Wacom W9002 chip, that we assume is responsible for driving the Wacom Electro Magnetic Resonance (EMR) digitizer system.

In this system, developed by Wacom, a grid of wires embedded in the screen generate magnetic fields that induce current in a coil in the tip of the tablet pen, both powering it and indicating its position over the grid. The pen then wirelessly returns that location data, along with pressure and click information.

We also found the LCD display driver, a Samsung WiseView N52A2NE, similar to the driver found in the iPad 2.

Here's the ginormous version of the LCD display board so you can view it in all its glory.
