Abstract
A fingerprint identification device is directly integrated with and formed on a touch panel, a color filter (CF), a thin-film transistor (TFT) or a liquid crystal module (LCM). The fingerprint identification device improves the shortcoming of the conventional fingerprint identification device that it is necessary to first manufacture the fingerprint identification device on a silicon wafer and then integrate the fingerprint identification device with another component. Moreover, the fingerprint identification device has much higher fingerprint identification precision.
