Embodiment Construction

[0019] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0020] Such as figure 1 As shown, the near-eye display system includes a microdisplay 10 that can be used to display an image 70 for a user of the near-eye display system. The microdisplay 10 may be a transparent microdisplay 10 such that a user can view real world objects through the microdisplay 10 while overlaying computer generated content on the real world objects by presenting computer generated images 70 on the display. The microdisplay 10 may be formed from an array of transparent ...

Abstract

The invention relates to the technical field of near-to-eye display, in particular to a near-to-eye display system and device capable of automatically adjusting transparency. The near-to-eye display system comprises: a micro display screen which displays an image; a waveguide system which comprises a waveguide sheet, the waveguide sheet presents the natural light for watching, and presents an image displayed by the micro display screen on the natural light to enter human eyes; and a color-changeable layer which enables the part, presenting natural light, of the waveguide sheet to become dark or enables the part to be invisible. The near-to-eye display system can automatically reduce the transparency along with the enhancement of external light, so that a user can normally use the near-to-eye display system under the action of outdoor strong light, and the scene application range of display equipment is expanded.

Description

technical field [0001] The invention relates to the technical field of near-eye display, in particular to a near-eye display system and device for automatically adjusting transparency, and a near-eye display device. Background technique [0002] Augmented reality is a technology that integrates virtual information with the real world, and the near-eye display device is a key link in augmented reality technology. The near-eye display device allows users to see the real world while seeing the virtual image constructed by the computer. Due to the limitation of the brightness of the light source of the micro-display image, the brightness of the virtual image seen by the human eye is limited. When the user uses the near-eye display device outdoors, the external light source is too large. If it is too strong, the contrast of the virtual image will decrease, making it difficult to see the virtual image superimposed on the real world, affecting the user experience. At present, the ...
