Abstract
The invention provides a liquid crystal, TFT display with driver lines folded around a light pipe and a digitizer. The digitizer has grid routing lines folded around a shield where the shield is connected to a shield of the computer system electronics. The display drivers and grid controller are mounted inward of an edge of the display. The glass layers surrounding the beads can have different thicknesses and composition while the liquid crystal surrounding the beads can be at a pressure less than atmospheric pressure. A surface of the display provides pen/pencil on paper feel as a digitizer pen is moved across the surface via hardness coatings and surface topography.
