AI summary

A teleprompter includes an accommodating space and an optical assembly disposed in the accommodating space. The accommodating space is configured for accommodating an electronic device including an image display unit and a lens. The image display unit is configured to emit a light along a first path. The optical assembly includes a light-reflecting unit and a beam-splitting unit. The light-reflecting unit is configured to divert the light from the first path to a second path and has a first light-reflecting portion disposed on the first path. The beam-splitting unit is disposed on the second path and is configured to allow a first portion of the light to transmit and divert a second portion of the light from the second path to a third path. The third path has a same direction as a direction of an optic axis of the lens.
