Patent ID: 11900712
Assignee: INTEGRATED BIOMETRICS, LLC
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A system for capturing a biometric object print image, comprising:
an electrophoretic display comprising an electro-optical material that produces a change in optical properties in response to an applied electric field, the electro-optical material comprising micro-capsules that comprise a negatively charged dark pigment suspended in a transparent fluid;
a bottom electrode electrically coupled with a first electrical bias supply, the bottom electrode electrically coupled with the electro-optical material; and
a first top electrode electrically coupled with a second electrical bias supply;
wherein the first top electrode operably, electrically couples with a biometric object;
wherein bringing the biometric object into contact with the electrophoretic display completes an electrical circuit between the top electrode and the bottom electrode in a first electrical bias mode resulting in the dark pigment of the microcapsules becoming visible at the surface of the electrophoretic display merely at a location of contact of the biometric object with the surface of the electrophoretic display, thereby generating an image of a print of a portion of the biometric object that contacts the electrophoretic display; and
wherein removing the biometric object from contact with the electrophoretic display results in the image of the print of the biometric object remaining on the surface of the electrophoretic display.
