Abstract
A light field near-eye display device and a light field near-eye display method are provided. The light field near-eye display device includes a processor, a display panel, and a lens module. The processor calculates new ray tracing data based on a current eye relief, preset eye relief data, and preset ray tracing data, and adjusts preset image data according to the new ray tracing data to generate adjusted image data. The display panel is coupled to the processor and emits an image beam according to the adjusted image data. The lens module includes a microlens array and is disposed between the display panel and a pupil. The image beam is incident to the pupil through the lens module and displays a light field image.
