Today's smart phones and wireless networks are changing our real lives, and in recent years AR-related products have gradually entered our lives. Through the integration with reality, AR has brought us a brand new vision. In addition to mobile phones, AR glasses are undoubtedly the best way to connect the real world and the virtual world.
Recently, SZLN Optoelectronics Technology Co., Ltd. released the industry's first binocular full-color MicroLED optical waveguide AR glasses. This product has many characteristics that are different from other products.
Natural and comfortable wearing of AR glasses products is the most important use requirement of users. This requires optical components and micro-displays to be sufficiently light and thin, low power consumption, at the same time, the transmittance of the lenses is required to be high, and the display must have sufficient brightness. Only in this way can it be used normally under outdoor ambient light. However, no matter which AR product it is, it cannot meet the three characteristics of comfortable wearing, high-brightness and full-color, and long-lasting battery life.
Optical waveguide technology brings the ultimate light and thin wearing experience
If you want to wear comfortably, weight control is very important. The optical waveguide technology allows the transmission of the optical path in the optical waveguide lens to achieve a full refraction effect. This process does not cause light leakage or loss, but also because of its lightness and external light. It is considered to be the best optical solution for consumer AR glasses due to its high penetration characteristics.
However, holographic waveguides are very sensitive to light wavelengths, and the transmission of some large angles of light can easily cause problems such as uneven brightness and rainbow patterns. In response to this problem, most companies in the industry previously used multilayer waveguide technology to solve this problem, but the multilayer solution has compromised in terms of weight and cost.
Faced with the problem of holographic waveguides, Thunderbird has achieved a balance between efficiency, dispersion, and mass production through self-developed light wave coupling analysis and optimization algorithms after years of research and development, and is the first to use high refractive index wafer glass, which greatly reduces With the critical angle of total reflection, large-angle light can also be transmitted by waveguide, and finally the optimal single-layer waveguide architecture is developed.
After the problem of light propagation is solved, what remains is the miniature display screen. Compared with other technical solutions, MicroLED has many advantages such as self-illumination, wide color gamut, high brightness, and compactness of the optical machine. MicroLED can be said to perfectly solve the display needs of AR glasses, and achieve a sufficiently thin and powerful full-color display.
The combination of a single-layer ultra-thin holographic optical waveguide and a MicroLED screen realizes the simultaneous presentation of real scenes and virtual information without blocking each other, and the real integration of reality and virtual reality. The use of diffractive optical waveguides with holographic volume gratings and MicroLED technology has become the final solution for the Pioneer version of Thunderbird smart glasses.
Breakthrough in full-color MicroLED technology solutions
Since the red, green, and blue three-color MicroLEDs cannot usually be generated on the same substrate at the same time, the realization of color MicroLEDs has become a new difficulty. The mainstream solution in the industry is to use a pure green display, which also reduces the actual user experience.
In terms of display, SZLN is not satisfied with the monocular monochromatic industry technical solution. It also brings users a color display with richer display information, while ensuring that the information and content can be seen clearly in the sun and the daily wear and use time.
Relying on the accumulation of technology in the display field, the Thunderbird Smart Glasses Pioneer Edition has closely arranged light-emitting machine tubes smaller than 4 microns on the substrate to self-illuminate, without a separate backlight, and can obtain purer black and brighter white. . At the same time, SZLN innovatively developed its own unique "full-color micro-display engine", taking into account brightness and energy consumption, and finally realized the perfect combination of full-color Micro LED and single-layer ultra-thin holographic optical waveguide in the smallest size.
Multi-scenario application brings a new user experience
After solving the most basic user needs of users such as comfortable wearing, high-brightness full-color, and low power consumption, the SZLN Smart Glasses Pioneer Edition has also improved the functions and applications, bringing users a more technologically-sense and easier-to-use experience.
In terms of functions and scenarios, the SZLN Smart Glasses Pioneer Edition can realize basic information prompts, photo sharing, photo translation, and intelligent connection control. It will also successively launch multi-screen presentation, real-scene navigation, real-scene translation, car mirror linkage and other functions.
At home, the SZLN Smart Glasses Pioneer Edition can be intelligently interconnected with Maoyan and door locks to obtain real-time information from Maoyan and control the opening of the smart door lock. After going out, you can turn off various smart devices running at home with one key.
When traveling abroad, the navigation information can be updated in real time through AR, which can fit the real scene and realize simpler and easier-to-understand road navigation. When you see a beautiful or interesting moment, you can take the moment in front of you with just two taps, and the photos are directly synced to your mobile phone and the cloud.
In office scenarios, SZLN Smart Glasses Pioneer Edition can present multiple screens in front of your eyes at the same time to facilitate your daily work.
The existing AR glasses products on the market often can only provide monocular monochrome display due to the difficulty of implementation, or increase the weight and thickness to achieve clear display effects. The SZLN smart glasses pioneer version starts from the perspective of actual use by users. Break through technical limitations and bring users more valuable products.
Devices such as AR glasses are currently only a kind of imagination and yearning for life in the eyes of many people. SZLN allows users' imaginations to not only stay in imagination, but also to truly combine the real world and virtual world, bringing users a completely different experience, and allowing more people to enjoy the changes brought about by science and technology.
