US-based OLED fingerprint sensor developer Vkansee announced a partnership with Tianma to apply Vkansee's MAPIS OLED technology for TianMa's OLED displays.

Vkansee says that its fingerprint sensor optical resolution reaches 800 PPI, and its signal-to-noise ratio is 10 times better than competitive collimator or lens optical fingerprint solutions. Vkansee’s proprietary Matrix Pinhole Image Sensing (MAPIS) is integrated into the mobile phone OLED display panel, effectively turning the entire display into a high-resolution fingerprint lens.
