ELECTRO-LUMINESCENCE IMAGE SENSOR FOR FINGER-PRINT

摘要

The present invention relates to an electro-luminescence (EL) fingerprint recognition sensor. According to one aspect of the present invention, a unit pixel of the EL fingerprint recognition sensor is provided. The unit pixel comprises: a substrate having a light receiving unit configured to detect incident light; first to n^th metal lines placed on an upper portion of the light receiving unit and defining a light incidence path; a light emitting layer placed on an upper portion of the n^th metal line; and a contact electrode placed on an upper portion of the light emitting layer to respond to the light incidence path and coming into contact with the light emitting layer. The present invention provides an EL fingerprint sensor capable of being miniaturized and generating a vivid finger print image.
