Tiny MicroLED Display from Mojo Vision Features Highest-Yet Pixel Density
Mojo Vision’s new microdisplay is just 480μm (or 0.48mm) across, smaller than a grain of sand. The display seems to be targeted at the virtual reality and or augmented reality markets. But, maybe not.indoor full color led display screen
Mojo Vision is heavily involved in what it calls Invisible Computing, a somewhat nebulous concept. Mojo Vision’s website copy makes references to the technology allowing us to “focus on a world around us and give us access to immediate and relevant information wherever we go, without distraction.”
This would seem to suggest that the company’s goal is to allow consumers to access digital information at the same time that they view the real, physical world around them.
In any case, the company is being somewhat coy about its purpose. According to Steve Sinclair, the senior vice president of product and marketing, the Mojo Vision LED display “is one piece of several building blocks that we have to have in place to build the product that we’re making,”The new display sports 14,000 pixels per inch. This is over two orders-of-magnitude greater than the pixel density of most smartphones.
The new display is 0.48 mm across, and according to Paul Martin, VP for displays, “The pixels are 1.3 [micrometers across], which means that the gap is only 0.5 µm. Smaller gaps creates harder and harder problems of fabrication.”GaN (gallium nitride) technology is well known to power engineers, and the material can also be used to fashion LEDs. Among their advantages over the now dominant OLED (organic light-emitting diodes) technology is that they consume about 10% of the power and shine almost ten times as bright.
This by itself makes them a great bet for smartphones—viewable in daylight and longer time between charges. And, it’s also quite relevant for devices like virtual reality headsets and heads up displays (HUDs).
