Introduction to Fingerprint Recognition Technology: Principles of Fingerprint Recognition Using different sensor characteristics, the physical changes produced by the fingerprint can be converted into electrical signals, and the output electrical signals are converted into fingerprint images by signal processing. Technologies are divided into optical, capacitive, thermal and ultrasonic, etc.

Innolux fingerprint recognition technologies

• The evolution of panel manufacturing
• A new type of fingerprint sensor integration sensing and TFT driving technology
• Technical description

• I. Optical type : By using the difference of light reflection signal between ridge and valley
