Augmented reality display optical system and display method

Abstract

The invention discloses an augmented reality display optical system and display method, wherein the system comprises an image encoder which obtains an image needing to be displayed, carries out the encoding of the image, and transmits the encoding information to a UV laser; the UV collimating laser receives the encoding information of the image encoder and emits UV laser to the display screen according to the encoding information; a plurality of pixel blocks are distributed on the display screen in an array mode, each pixel block comprises a quantum dot light-emitting layer, a light reflectinglayer is arranged on the side, away from the human eye observation position, of each quantum dot light-emitting layer, and a micro lens layer is arranged on the side, close to the human eye observation position, of each quantum dot light-emitting layer. The embodiment of the invention provides a technical scheme. Under the control of the image encoder, UV laser is emitted, the UV laser irradiatesdifferent pixel blocks according to frequency change and direction change as required to form different information, and the information of a plurality of pixel blocks is spliced and converged into eyes of an observer to form a whole image needing to be displayed.

Description

technical field [0001] The present invention generally relates to the field of augmented reality, and in particular to an augmented reality display optical system and a display method. Background technique [0002] With the development of science and technology, augmented reality display technology will have important applications in the military, industry, and personal consumption directions, and it is likely to become the mainstream display method of the next generation. However, the current optical system for augmented reality display, that is, AR (Augmented Reality, Augmented Reality) optical system, generally has the characteristics of large volume and low light efficiency, which seriously restricts the practical application of AR display technology.

However, the current optical system for augmented reality display, namely AR (Augmented Reality, augmented reality) optical system, generally has the characteristics of huge volume and low light efficiency, which seriously restricts the practical application of AR display technology.

[0003] Examples of conventional AR optical systems according to optical principles are: free-form surface prism type, the display fiber is finally accepted by the human eye after multiple reflections of the free-form surface prism, this kind of solution generally has a large thickness and volume of the prism, and it is difficult to achieve thin and light Glasses display; another representative one is the optical waveguide type. The light of the display screen is collimated by the optical system and then enters the waveguide plate. Pupil dilation, although the lens is thinner in this way, after the light is refracted and propagated by the microstructure for many times, the brightness of the final incident to the human eye is very low, and the utilization rate of light energy is low
