A method and apparatus for integrating a personal information device on a mobile computer that includes activating a first mode to display data originating with the PID in a first display area of a display. The set of spacers includes a porous spacer that is as wide as the spacer that restores the desired anatomical spacing. The pyrimidopyrimidine derivatives may be pyrimidopyrimidine oligothiophene derivatives in which an oligothiophene having p-type semiconductor characteristics may be bonded to a pyrimidopyrimidine having n-type semiconductor characteristics positioned substantially in the center of the molecules, thereby simultaneously exhibiting both p-type and n-type semiconductor characteristics. Subsequently, a protection layer is formed over the substrate.
