FINGER SENSOR INCLUDING CAPACITIVE LENS AND ASSOCIATED METHODS |
摘要 |
<p>A finger sensing device may include a mounting substrate, an integrated circuit (IC) die carried by the mounting substrate and having an array of electric field-based finger sensing elements, and first electrical connections coupling the mounting substrate and the IC die. In addition, the finger sensing device may include a protective plate attached over the array of electric field-based finger sensing elements and having a dielectric constant greater than 5 in all directions and a thickness greater than 40 microns to define a capacitive lens for the array of electric field-based finger sensing elements. The finger sensing device may also include an encapsulating material adjacent the mounting substrate and the IC die and around at least the first electrical connections.</p> |
