Augmented reality display system and display method thereof

An augmented reality display method, comprising:

• obtaining an environment information through an input unit;
• transmitting the environment information to an operation processor;
• operating and processing the environment information to generate an output information, wherein the operation processor determines a display sequence, a display size, a display brightness, and a display color of the output information according to an importance weight;
• transmitting the output information to an output unit;
• and
• providing the output information to a user, wherein the output unit provides a light beam corresponding to the output information through a transparent display, and the output unit transmits the light beam to eyes of the user through a first lens having a negative refractive power, a second lens having a negative refractive power and a third lens having a positive refractive power to generate an augmented reality image, wherein the transparent display, the first lens, the second lens, and the third lens are arranged in sequence from a display side to an eye side;
• the first lens is disposed between the transparent display and the second lens;
• the second lens is disposed between the first lens and the third lens;
• the third lens is disposed between the second lens and an eye of the user;
• light from a background penetrates through the transparent display, the first lens, the second lens, and the third lens in sequence, and is then transmitted to the eyes;
• the transparent display is cemented to the first lens to form an optical component;
• wherein the output unit is disposed on a motorcycle helmet, and the output information comprises vehicle approach warning information, road warning information, intersection sign information, vehicle speed, engine speed, navigation information, inter-vehicle communication warnings of road and car conditions in vehicle network, weather information, time information, calls and mails display, information regarding Internet of Things, smart city sharing information or a combination thereof.

An augmented reality display system, comprising:

• an input unit, configured to obtain an environment information;
• an operation processor, configured to operate and process the environment information provided by the input unit to generate an output information, wherein the operation processor determines a display sequence, a display size, a display brightness, and a display color of the output information according to an importance weight;
• and
• an output unit, configured to transmit the output information provided by the operation processor to a user, the output unit comprising:
• at least one display module, comprising a transparent display, a first lens having a negative refractive power, a second lens having a negative refractive power, and a third lens having a positive refractive power arranged in sequence from a display side to an eye side, wherein the first lens is disposed between the transparent display and the second lens;
• the second lens is disposed between the first lens and the third lens;
• the third lens is disposed between the second lens and an eye of the user;
• each of the first lens and the second lens is a cylindrical Fresnel lens having a Fresnel surface having a plurality of strip teeth;
• the third lens is a cylindrical lens,
• wherein the transparent display of the at least one display module is configured to emit a light beam, and the light beam is incident into eyes of the user on the eye side through the first lens, the second lens and the third lens in sequence so that the eyes see an augmented reality image located on the display side, and light from a background penetrates through the transparent display, the first lens, the second lens, and the third lens in sequence, and is then transmitted to the eyes, and the transparent display is cemented to the first lens to form an optical component.
