摘要： An optical fingerprint identification system includes a base, a photo sensor, a light emitting layer and a cover. The photo sensor is disposed on the base. The light emitting layer is disposed above the photo sensor, and the light emitting layer includes a light emitting element. The cover is disposed above the light emitting layer. The optical fingerprint identification system further includes a condenser unit and a light receiving element between the photo sensor and the cover. The condenser unit is disposed above the photo sensor. The light receiving element is disposed above the condenser unit. The light emitting element is disposed away from the photo sensor, the condenser unit and the light receiving element in a sideway direction that is different from a stack direction of the optical fingerprint identification system.
