Description

Technical Field

[0001] The utility model relates to the field of XR technology, and specifically to an XR wearable display device. Background Art

[0002] XR technology is a general term that includes augmented reality (AR), virtual reality (VR) and mixed reality (MR). These technologies are advanced technologies based on computer vision and perception technology, which can combine the virtual world and the real world to create a new digital experience. During use, they need to be displayed in conjunction with wearable display devices.

[0003] In order to include the external real scene in the user's field of vision, the existing AR and MR glasses adopt the method of adding two cameras to imitate the principle of human eye imaging, and map the images taken by the cameras on the internal screen, so that the external scene can be seen during use. However, this solution will cause the external real scene to be processed by the camera CMOS, central processing unit, etc. before it can be presented. Due to the performance of the camera, screen and chip, it will inevitably cause image delay and insufficient image clarity, and will also increase the computing burden of the device, which needs to be optimized and improved.
