    • Provided is a fingerprint sensor using a microlens including the microlens changing a path of light reflected by a fingerprint structure, and an optical-TFT checking the fingerprint structure from the light whose path is changed. Since the microlens including the spherical lens to change the path of light is provided, the amount of light incident on the light measuring area can be maximized. Also, since the noise such as dispersed light is exhausted by the spherical lens outside the light measuring area, the effect by the noise can be minimized.
    • 提供了使用包括微透镜的微透镜的指纹传感器,该微透镜改变由指纹结构反射的光的路径,以及光路TFT,其从路径改变的光检查指纹结构。 由于提供了包括改变光路的球面透镜的微透镜,因此可以使入射到光测量区域的光量最大化。 此外,由于诸如分散光的噪声由球面透镜在光测量区域外部排出,所以可以使噪声的影响最小化。
