Abstract
One or more systems and/or methods are disclosed for building a relief print generator with no bezel. An electrode layer having more than one electrode can be used in an electrode-based, electro-luminescence component of the relief print generator. The respective electrodes may be connected to power sources with different voltage phases. An electrical circuit can be created between a biometric object and more than one electrode in the electrode layer when the biometric object contacts a surface of the generator. The electro-luminescent component can be activated by electrical charge and emit light indicative of a relief print of the biometric object. A contact electrode outside the electrode layer may not be used, which may allow for the removal of a bezel from an example device.
