Problems solved by technology

[0002] In the existing HMD (Head Mount Display, head-mounted visual device) virtual reality/augmented reality display system, most of the optical display systems are designed according to a fixed imaging distance, so the image source is displayed in front of the human eye after passing through the optical display system The distance between the virtual image and the human eye is fixed. This kind of display without image depth of field will cause Vergence-Accommodation Co

Abstract

The invention discloses an image depth modulation module. The image depth modulation module comprises a plurality layers of electric control dimming plates arranged in a stacked mode, wherein each layer of electric control dimming plates is composed of a plurality of electric control dimming units; and each electric control dimming unit is provided with an independent switch, and each electric control dimming unit can be regulated to be in a transmission state or a scattering state. Meanwhile, the invention also discloses a display module applying the image depth modulation module and near-eyedisplay equipment; and an image is loaded with depth of field through a physical structure, so that pixel-level or quasi-pixel-level depth-of-field adjustment is realized, a visual vergence-accommodation conflict effect can be solved, the image observed by human eyes better conforms to the focusing habit of the human eyes, and the depth arrangement of the display image is closer to the depth lawof the real light field.

Description

technical field [0001] The invention relates to the field of image display, in particular to an image depth modulation module, a near-eye display optical module and a near-eye display device using the image depth modulation module. Background technique [0002] In the existing HMD (Head Mount Display, head-mounted visual device) virtual reality / augmented reality display system, most of the optical display systems are designed according to a fixed imaging distance, so the image source is displayed in front of the human eye after passing through the optical display system The distance between the virtual image and the human eye is fixed. This kind of display without image depth of field will cause Vergence-Accommodation Conflict (VAC), resulting in "motion sickness", and the user experience is extremely poor. And if such an HMD device is used for augmented reality applications, since the distance between the virtual image and the human eye is constant, and the environment is c...
