Optical fingerprint recognition module and electronic device

摘要: An optical fingerprint recognition module and an electronic device. The comprises: a reflective plate (30), modulation means (40) sensing element (10). (30) the (10) are provided one above other, first gap is formed between (30). in gap. comprises region (32) located on side of (40), so that light reflected by finger enters after passing through (32). Thus, light, having signal, modulated then outputted. path folded, effectively reducing thickness whilst ensuring performance.
