  • Patent number: 10733410
    Abstract: An optical operating module including a light-emitting element, a light guide element, a display panel, and a control element is provided. The light-emitting element includes a first light-exit surface, an electrical connector and a light-emitting unit. The light guide includes a first light-receiving surface, a reflective surface, a first reflective surface, and a second light-emitting surface. The display panel is partially disposed on the light guide, and the other part of the display panel not disposed on the light guide forms an accommodating space with the light guide element, and includes a second light-receiving surface and a third light-exit surface. The control element is disposed in the accommodating space, and generates a control signal to control the light-emitting element after receiving a command of an action. The optical operating module provides abundant light and controls the controlled terminal after the fingerprint identification device recognizes fingerprints.
