[0003] However, in light-field near-eye displays, in addition to providing two-dimensional image data, three-dimensional information of the image light to be displayed must also be provided, which makes most light-field near-eye displays suffer from a sharp drop in image resolution.

Abstract

The invention discloses a near-eye display device, which includes a display panel, a liquid crystal layer and a lens element. The display panel is used for providing image light beams. The liquid crystal layer is arranged beside the display panel, and the image light beam passes through the liquid crystal layer. The liquid crystal layer is disposed between the display panel and the lens element. At least a part of the liquid crystal layer undergoes phase modulation to modulate image light beams. Compared with the existing near-eye display devices, the near-eye display device of the present invention has high resolution.

Description

technical field [0001] The present invention relates to a display device, and in particular to a near-eye display device. Background technique [0002] With the rapid development of near-eye displays (NEDs), light-field near-eye displays (NEDs) were born in order to make images seen by users wearing near-eye displays more realistic and comfortable. The biggest difference between the light field near-eye display and the traditional near-eye display is the mechanism of passing through the light field image, so that the light field near-eye display also has the advantage of greatly shortening the overall optical path length, making it possible to realize a thinner near-eye display. [0003] However, in light-field near-eye displays, in addition to providing two-dimensional image data, three-dimensional information of the image light to be displayed must also be provided. As a result, most light-field near-eye displays suffer from a sharp drop in image resolution. Therefore, ho...
