A stated goal of Mojo Vision (Saratoga, CA) is to use “AI to look beyond today’s mobile form factors and develop new ways to connect the world to important information.”
In an effort to achieve this goal, the company is developing technologies to support so-called invisible computing. Invisible computing “imagines a world where information is there when you need it” and that the “technology fades away” allowing the user to “freely connect with others in a more meaningful and confident way.”
Part of the hardware means by which the company is attempting to implement invisible computing involves development of what is claimed to be the world’s smallest and densest microdisplay. The thinking on the part of the company is that tiny pixels can enable a nearly invisible, low-power display device.
To that end, the company is developing a very tiny, microLED based display. Although few details related to the display device have currently been made available to the public, it has been disclosed that Mojo Vision builds gallium-nitride microLEDs as an array and then bonds the array to a silicon CMOS backplane.
The Mojo display is reported as requiring approximately 10 percent of the power consumed by an otherwise equivalent liquid crystal display. Furthermore, the Mojo display produces 5 to 10 times the brightness of an otherwise equivalent OLED. The company claims that the light output of their device is such that the display can be read with ease even in a bright ambient, outdoor environment.
The Mojo monochrome microLED display is 0.48 mm across having a pixel pitch of 1.8 µm. This translates to over 14,000 ppi and a density of over 200 mppi2. To put these dimensions into context, the Mojo microLED display has a pixel density that is about 300 times greater than that of a conventional smartphone display.
Comparative and magnified images of the display are presented in the figures below.

Mojo Vision has indicated that, at a future date, further details will be released on the company’s microLED display as well as other, related matters.
Although incredibly small, Mojo has stated that the company is actually working on displays with even smaller pixels. The stated goal is to eventually produce a display with a pixel resolution that matches the resolution of the human eye.
So….given this display hardware, it is fair to ask: what will be the company’s initial product?
In answer to this question, the only comments so far offered by the company are along these lines: Mojo Vision was stated with a particular application in mind. This application is self-described as “something pretty audacious.” With a density of 200 million pixels per square inch, the display is perfect for the application under development and that the microLED display is just one of several building blocks needed to create the ultimate product.
Given these characteristics as background, one online commentator has speculated that the mystery product could be contact lens-based. Stay tuned to Display Daily to learn of further developments at Mojo Vision. -Arthur Berman
