More Information
Summary:Disclosed is an optical film for fingerprint recognition that transmits infrared rays. The optical film for fingerprint recognition may include a base film and a prism pattern layer adhered to one side of the base film. Here, in the prism pattern layer, a plurality of prisms including an infrared absorber may be disposed parallel to each other at a predetermined interval to form a line pattern that transmits the infrared rays. The optical fingerprint authentication using infrared rays can be performed even in small electronic devices such as smartphones. 적외선(infrared)을 투과하는 지문인식용 광학필름을 개시한다. 지문인식용 광학필름은 베이스필름 및 상기 베이스필름의 일 측에 접착되는 프리즘패턴층을 포함할 수 있다. 여기서, 상기 프리즘패턴층은 적외선 흡수제를 포함하는 복수의 프리즘이 기정의된 간격으로 서로 평행하게 배치되어 상기 적외선을 투과하는 라인(line) 패턴을 형성할 수 있다.
