Lumiode: microdisplays with Led technology for Google Glass type devices

Maximum visibility and luminosity to view notices and information on a microscreen like the one used by Google Glass is the objective of the development of Lumiode, that uses LEDs for this type of devices.

Lumiode is the name of the American startup working on developing a head-worn microdisplay for next-generation devices., like Google Glass, that offers maximum visibility and luminosity to clearly see the information, como informa MIT Technology.

Unlike most current screens on portable devices, with a back that emits light and uses filters to compose the individual colored pixels that make up the images, Lumiode's solution uses Leds as pixels, which are more efficient by not losing light through filtering.

As the founder and CEO of Lumiode explains, Vincent Lee, the result will be smaller portable screens and projectors, brighter and more energy efficient that fit with daily activity, although as they point out from Google, It may be difficult to use the projected Glass screen in broad daylight.

Among the challenges of this technology is battery life and that, just like smartphone screens, that use LEDs as a light source behind the screen, Images are created when light passes through filters, which in addition to reducing luminosity increases consumption, since the LEDs must always be on.

The development of Lumiode has been carried out at the Columbia University Laboratory of Unconventional Electronics and is based on recording LED series patterns, adding a thin layer of silicone on each one to control the amount of light each LED emits, so the image component is the Led itself, instead of using it as a backlight.

According to Lee, The manufacture of this microdisplay is not expensive, since it uses standard components and processing techniques, and assures that this technology is “thirty times brighter and ten times more efficient than other screen technologies”.

The largest prototype developed to date by this company has a square millimeter with 50×50 Single color LEDs, Although Lee estimates that he will create a prototype of 320×240 pixels next year and that the rest of the colors will probably be generated by adding a special layer on top of the chip.

Lumiode points out that it will be then when it can partner with electronics manufacturers to incorporate this technology not only for portable microdisplays., but even to project information on the windshield of a car.

In addition to Lee, John Sarik is part of the founding team of the company, John Kymissis and Brian Tull.
