Claim:
1. A two-sided touch screen unit comprising: a housing; a first touch screen positioned in the housing and facing a first direction; a second touch screen positioned in the housing and facing a second direction that is substantially opposite of the first direction; and at least one attenuation layer positioned between the first touch screen and the second touch screen; a first backlight diffuser coupled between the attenuation layer and the first touch screen, and a second backlight diffuser coupled between the attenuation layer and the second touch screen; a backlight diffuser, a first attenuation layer coupled between the first touch screen and the backlight diffuser, and a second attenuation layer coupled between the second touch screen and the backlight diffuser, wherein each of the first and second attenuation layers are coupled to an electrical ground; wherein the at least one attenuation layer prevents a touch on the first touch screen from being registered by the second touch screen to enable each touch screen to operate independently of the other touch screen; wherein the attenuation layer is an electrically conductive wire mesh, wherein the wire mesh is coupled to said electrical ground; wherein the first and second attenuation layers each comprises a conductive film on their respective sides of the backlight diffuser; wherein a user input on the first touch screen is receivable concurrently with a user input on the second touch screen; wherein each of the first and second touch screens includes a protective layer, a touch sensor, and a display arranged between the protective layer and the touch sensor; wherein each of the first and second attenuation layers includes a plurality of apertures; wherein the attenuation layer includes a recess having one or more batteries contained therein; wherein the attenuation layer includes a recess having electronic circuitry contained therein; wherein the attenuation layer includes a recess having conductive paint applied to its surfaces therein; wherein the touch sensor is a capacitive touch sensor; wherein the attenuation layer includes a plurality of apertures; and, wherein the attenuation layer comprises a non-transparent material.
