Three dimensional interactive display
First Claim
1. A three-dimensional (3-D) interactive display comprising:
- a display screen;
an array of capaciflective pixels disposed upon said display screen;
a first group of sensor pads connected to ones of said array of capaciflective pixels;
a second group of sensor pads connected to ones of said array of capaciflective pixels, capaciflective pixels connected to said first group of sensor pads not being connected to said second group of sensor pads thereby forming a transparent capaciflector camera; and
an operational amplifier connected to each of said sensor pads, each said amplifier biasing and receiving a signal from a connected sensor pad responsive to intrusion of a probe disposed in front of said display screen, said signal being proportional to probe positional location with respect to said display screen so as to facilitate a direct 3-D input to said display screen.

Abstract
A three-dimensional (3-D) interactive display and method of forming the same, includes a transparent capaciflector (TC) camera formed on a transparent shield layer on the screen surface. A first dielectric layer is formed on the shield layer. A first wire layer is formed on the first dielectric layer. A second dielectric layer is formed on the first wire layer. A second wire layer is formed on the second dielectric layer. Wires on the first wire layer and second wire layer are grouped into groups of parallel wires with a turnaround at one end of each group and a sensor pad at the opposite end. An operational amplifier is connected to each of the sensor pads and the shield pad biases the pads and receives a signal from connected sensor pads in response to intrusion of a probe. The signal is proportional to probe location with respect to the monitor screen.
