Abstract

The invention discloses an AR display device which comprises a display lens, a power supply component, a motion detection component and a control component. The display lens comprises an electrochromic layer, the motion detection component detects the motion parameters of the AR display device and outputs the motion parameters to the control component, the control component determines a first output voltage according to the motion parameters and sends a first output voltage to the power supply component, and the power supply component supplies power to the electrochromic layer according to thefirst output voltage so as to adjust the transmittance of the electrochromic layer. When the transmittance of the electrochromic layer is adjusted to be higher according to the motion parameters, thetransmittance of the display lens is higher, so that a user can clearly see the environment of the real world through the display lens when using the display lens; and when the transmittance of the electrochromic layer is adjusted to be lower according to the motion parameters, the electrochromic layer can provide a darker display background for the display lens, so that the contrast ratio and the definition of a display image of the display lens are improved, and the user experience is improved. The invention further discloses a transmittance adjusting method of the AR display device and a wearable system.

Description

technical field [0001] The present application relates to the field of augmented reality (Augmented Reality, AR), in particular to an AR display device, a method for adjusting its transmittance, and a wearable system. Background technique [0002] AR is a technology that ingeniously integrates the information of the virtual world with the real world. It can not only effectively reflect the information content of the real world, but also promote the display of the information content of the virtual world. Specifically, the environment of the real world (the actual scene ) and the image of the virtual world (virtual scene), they can exist simultaneously in the same screen and space, and can be perceived by the user. [0003] AR display devices are usually presented in the form of glasses, which usually include display lenses. The image content of the virtual world will be viewed by the user through the display lenses. In addition, the user can also see the real world environme...
