指纹感测装置;FINGERPRINT SENSING APPARATUS

摘要

本发明提供针对用于指纹辨识之一薄型高对比度光学采集系统之方法及装置。在一项实施例中，一种用于判定一指纹之有效性之装置包含一光折射器件(光折射器)、一光源、一光收集器件及一控制器。;该光折射器件可例如系具有反向电流量测及放大电路之一TFT光面板结构或一主动矩阵有机发光二极体(AMOLED)面板结构，且包含一成像表面及一观视平面。来自该光源之入射光直接或间接投射至该成像表面上以自该投射光产生图案化物件之一影像至该观视平面上。与知光学指纹采集装置相比，该装置经组态以具有一薄的形状因数，其可能系挠性或可保形的。;The light refracting device can, for example, be a TFT light panel structure or an active matrix organic light emitting diode (AMOLED) panel structure with reverse current measurement and amplification circuitry, and includes an imaging surface and a viewing plane. Incident light from the light source is projected directly or indirectly onto the imaging surface to create an image of the patterned object from the projected light onto the viewing plane. The apparatus is configured to have a thin form factor, which may be flexible or conformable, compared to conventional optical fingerprint acquisition apparatuses.
