This screen with a diameter of 0.48mm conceals the mystery.

Imagine that when you blink your eyes, all the icons of Internet applications appear in front of you, you focus on the music player, the melodious music sounds, and you look away, the music stops Is this scene very similar to the scene in some games?
This is not a game or a movie, but Mojo Vision’s latest smart contact lens Mojo Lens at 2020 CES-a product that incorporates AR technology into contact lenses. This contact lens has a built-in micro display, and when worn, you can view AR images directly in front of your eyes.
Empower your eyes
Since there is no finished product for this product, for the time being, people can only experience this future technology through VR headsets.
From the perspective of experience, this contact lens can not only display time, weather, health data, latest news and other text content, it can also sense objects and track eye movements. It has an eye-control interface for data access and assists humans to perceive their surroundings in the dark.
Most importantly, while providing information, Mojo Lens will not interrupt the focus of the human eye and cause visual distress.
Mojo Vision CEO Drew Perkins said in a statement: “Its goal is to provide information when you need it, without bombing it, and not distracting you when it is not needed. Force. “
In a presentation for media reporters, the company’s executives showed how contact lenses project a Micro LED display onto the retina, allowing users to see a virtual teleprompter, navigation instructions, and Other interactive features floating in view.
Users wearing contact lenses can “click” an icon by focusing on it—for example, starting a music player, but turning it off by shifting their eyes.
To see the image in front of you, the display is the core of Mojo Lens. It is located directly in front of the pupil and can project and focus light to a specific area of the retina at the back of the eye. Because the display was too small, only 0.48 mm in diameter, and close enough that his presence was almost invisible to his eyes.
The display focuses light on a tiny recessed area called the fovea on the retina at the back of the eye. This area helps users see the details of the object in front of them.
This small depression only accounts for 4% to 5% of the area of the retina, but it contains most of the optic nerve endings and a large number of photoreceptor cells. It can convert light into electrochemical signals and transmit them to the brain through the optic nerve. Various visual centers.
Because the monitor injects light directly into a small area of the retina where the light is most visible, it requires less energy and light to transmit the image.
The most expensive screen
The key to the implementation of AR contact lens technology lies in that “micro-screen”, because it needs to be thin and light, but it must be able to display enough data.
The screen that can meet these requirements can only be made by Micro LED, with a diameter of only 0.48mm, but the pixel density is as high as 14000ppi, so the cost of this screen has also reached $ 108 million.
The reason why it is expensive is that its pixel density is ridiculously high, which is 30 times that of ordinary mobile phone screen pixels (Huawei mate30pro screen pixel density is 409ppi, Apple iPhone 11 Pro screen pixel density is 458ppi).
Foreign media Venturebeat once saw this monochrome screen showing an image of Einstein’s tongue. Of course, this image was enlarged after being displayed with a microscope, and the screen itself could not be taken with the camera.
Normally, a person with good eyesight has a resolution of about 9600 × 9000 pixels and a pixel density of 2183ppi, but it ’s difficult for a typical headset to achieve such a high pixel density. This is why some people wear VR / AR display devices have dizziness.
Samsung Gear VR glasses have a pixel density of 1200ppi. Google and LG jointly launched a VR display pixel density of 1443ppi. BOE’s AR / VR display launched three years ago has a pixel density of 1600ppi. The 0LED screen used in VR displays, although the pixel density is increasing, is not enough for VR glasses, let alone contact lenses in the eyes.
Introducing Sinclair, Vice President of Mojo Vision: The Micro LED technology used in Mojo contact lenses consumes 10% of the power of LCD displays and 5-10 times the brightness of OLEDs, which means that Mojo lenses can be comfortable outdoors. To use.
Thinner, more efficient, higher resolution, superior hue … many advantages make MicroLED seemIt is the perfect choice for AR / VR equipment. If Micro LED has disadvantages, it must be cost.
This LED is produced in a way that is almost a silicon chip (through preparation, testing and selection, assembly and packaging, final testing, etc.), and then it is transferred to a base plate full of pin grids. It’s like transferring a part of a computer chip to another computer chip, which needs to be done in batches over and over, and each step can go wrong.
Before the actual expansion of production capacity, the price of Micro LED will be very expensive. Mojo Vision vice president Paul Martin said the company must overcome several obstacles to make a display of 14,000 pixels per inch. “Single pixel size is 1.3 microns (diameter), which means that the gap is only 0.5 microns. Smaller gaps cause more difficult manufacturing problems.”
Temporary use in the medical field
Mojo Lens is still in development, but the company said it expects to deliver consumer-oriented products in two to three years.
It seems that this AR contact lens may be more used in the medical field.
Sinclair said, “Mojo Lens will be able to help people with low vision, such as macular degeneration, glaucoma, pigmented retinitis, night blindness. At the same time, it can also give us a certain degree of super power, let us see the impossible What you see. “
Mojo Vision announced on January 16 that they are working with the US Food and Drug Administration (FDA) to participate in the latter’s “Breakthrough Device Program” to help treat irreversible diseases.
The company also has a partnership with Vista, the blind and visually impaired center in California, a non-profit organization to provide rehabilitation services for blind or visually impaired children. Mojo Vision itself is also creating a medical device company, Mojo Lens’ technology will be integrated into the newly created company.
Can Mojo Lens succeed? There is currently no successful precedent for black technology that gives contact lenses new capabilities.
Google had wanted to design a contact lens with a circuit and chip attached to it to measure the blood glucose level of a diabetic patient based on the blood glucose level of tears. Samsung and Sony have also applied for smart contact lens patents. It is envisaged that the components can be photographed by “blinking”, and the pictures can be directly projected on the eyes.
None of the above plans or patents are applied to contact lenses, whether for blood glucose measurement or photography. Google even announced that because of “the lack of correlation between tear glucose and blood glucose”, the research and development work was stopped, and the “gospel for diabetic patients” was left to rest.
As a pair of concept glasses, Mojo Lens has a beautiful vision. It is not difficult to land. The screen is built on the basis of invisible eyes, not only to solve the problem of contact between parts and eyeballs, but also to solve problems such as power supply and disinfection of smart devices.
Although Mojo Vision plans to launch this product within two years, from the current issues, whether it is price or technical issues, there are still many things that need to be improved. This is not even the data and privacy issues on AR smart contact lenses. What should I do?
