Abstract
A control method of a light field display is provided. A control unit inputs a focal length signal to a zoom lens, so that the zoom lens is periodically switched among corresponding specific focal lengths. The control unit inputs a corresponding display signal to a display unit of a display module according to one of the specific focal lengths, and the display module generates one of image lights, the image lights respectively have different imaging distances corresponding to the specific focal lengths after passing through the zoom lens. The control unit inputs a corresponding response time signal to the display module according to one of the specific focal lengths, the one of image lights emitted by the display module passes through the zoom lens within one of response times, and the light field display projects the one of image lights to form an image at the corresponding imaging distance.
