Problems solved by technology

Chinese patent CN110610668A sets MicroLED chips and photovoltaic power generation units on the lens of AR smart glasses. While performing AR display, the photovoltaic power generation unit converts part of the ambient light irradiated on the glasses lenses into electrical energy. The disadvantage is that MicroLED chips and photovoltaic power generation The unit is installed in front of the eyeball to block / absorb the ambient light entering the eyeball, resulting in the "sunglasses" effect, and the user will have serious visual discomfort
[0004] Chinese patents CN110824699A, CN305791180S, etc. all provide eye tracking technology solutions for AR glasses. By arranging multiple infrared LED light sources inside the glasses frame, infrared light is provided to the surface of the eyeball. However, since the infrared LED light source arranged inside the spectacle frame can only illuminate the eyeball obliquely, the infrared camera can only capture part of the image of the eyeball, which makes it difficult to track the eyeball.

Embodiment 1

[0028] Please refer to figure 1 , an augmented reality glasses based on MicroLED display includes a lens frame 1, a mirror leg 2 and a lens 3, two lenses 3 and two mirror legs 2 are provided, and the lens 3 is embedded in the lens frame 1, so The temples 2 are arranged on the left and right sides of the lens frame 1, wherein at least one lens 3 is provided with a MicroLED display unit 4 on the inner surface, and the MicroLED display unit 4 includes a transparent substrate and a pixel unit. Arranged in an array on the substrate, each pixel unit includes a driving unit and a MicroLED chip 5, the driving unit is arranged between the transparent substrate and the MicroLED chip 5, and the MicroLED chip 5 includes a visible light MicroLED chip and an infrared light MicroLED chip The light emitted by the visible light MicroLED chip is in the visible light band for realizing monochrome display; the light emitted by the infrared light MicroLED chip is in the infrared band for providing...

Embodiment 2

[0036] Please refer to Figure 2 to Figure 3 The difference between the second embodiment and the first embodiment is that the visible light MicroLED chip 5 includes a first MicroLED chip 51, a second MicroLED chip 52 and a third MicroLED chip 53, and the wavelength of the light emitted by the first MicroLED chip 51 is Between 400nm and 500nm, the peak wavelength is 450nm, emitting blue light. The first MicroLED chip 51 contains at least one multi-quantum well light-emitting layer, which is formed by alternately stacking two semiconductor layers with different components and a thickness on the nanometer scale. The general chemical formula of the two semiconductor layers is Al x In y Ga z N (where x+y+z=1, 0≤x≤1, 0≤y≤1, 0≤z≤1). The wavelength of light emitted by the second MicroLED chip 52 is between 500 nm and 600 nm, with a peak wavelength of 525 nm, and emits green light. The second MicroLED chip 52 contains at least one multi-quantum well light-emitting layer, which is ...
