Abstract

The invention relates to the technical field of retina scanning display, and provides a near-to-eye display system and a near-to-eye display method. The near-to-eye display system comprises a scanning display device for scanning and projecting a light source to human eyes; the scanning display device comprises an optical phased array, a detection unit and a processing unit. The optical phased array is arranged on a light path between the light source and human eyes; the detection unit is used for receiving light rays reflected by human eyes and processing the light rays to generate a two-dimensional light spot pattern; the processing unit is used for calculating the wavefront difference of the light according to the two-dimensional light spot pattern; and the optical phased array is used for regulating and controlling own pixels according to the wavefront difference so as to compensate the aberration of human eyes. According to the near-to-eye display system and the near-to-eye display method, the eye aberration of different individuals can be detected and compensated, so that the image quality watched by different users can be optimized.

Description

technical field [0001] The present application relates to the technical field of retinal scanning display, and in particular, to a near-eye display system and a near-eye display method. Background technique [0002] Retinal Scan Display (RSD) refers to a new type of display technology that directly projects a display screen onto the user's retina by means of beam scanning. Because this display technology does not require a physical display surface, and only generates and modulates Therefore, it has the characteristics of small size and low power consumption, which is very suitable for near-eye display scenarios such as AR (Augmented Reality, augmented reality), VR (Virtual Reality, virtual reality), MR (Mixed Reality, mixed reality). [0003] Taking AR visual display technology as an example, its display system generally includes two parts: an optical engine and an optical coupler. The optical engine is used to generate a virtual image, and the optical coupler is used to map...
