We combine a low dark current and high‐detectivity near‐infrared (NIR)‐sensitive organic photodetector with a high‐resolution 508 pixels per inch (ppi) oxide thin‐film transistor (TFT) backplane to create a large‐area thin NIR detector, using processes that are compatible with flat‐panel display fabrication. The detector is characterized showing high uniformity and linearity. With the use of a NIR light source, the detector is capable of imaging the (pattern of) veins under the skin in reflection, leading to improved biometric authentication.

使用近红外有机光电探测器进行静脉检测以进行生物特征认证

我们将低暗电流和高检测灵敏度的近红外（NIR）敏感有机光电探测器与高分辨率的508像素/英寸（ppi）氧化物薄膜晶体管（TFT）背板相结合，以创建大面积的薄型NIR检测器使用与平板显示器制造兼容的工艺。该检测器的特点是显示出很高的均匀性和线性度。通过使用NIR光源，检测器能够对皮肤下的静脉（图案）进行反射成像，从而改善了生物特征认证。
