Under-display optical fingerprint technology mainly includes ultrasonic technology and optical technology. Compared with ultrasonic technology, optical technology has obvious advantages in terms of cost, image quality, anti-counterfeiting ability and so on. It is expected to become the main technology of under-display fingerprint recognition scheme.
1. Powerful anti-counterfeiting ability;
2. Lower cost.
1. A type of APS pixel circuit is developed exclusively, which better amplifies the signal. Full-screen recognition, multi-finger recognition and palmprint recognition can be realized in the future;
2. Multi-process compatibility, which can be applied to flexible rollup and medium-sized products with lower cost.
