Maximum visibility and brightness to display notices and information in a microdisplay such as using the Google Glass is the goal of developing Lumiode, which uses LEDs for these devices.


Lumiode is the name of the stat-up American who works in the development of a microdisplay that can be worn on the head for next-generation devices such as Google Glass, which offers maximum visibility and light to see clearly the information, as MIT Technology reports.

Unlike most of the actual screens on portable devices, with a rear that emits light and uses filters to compose the pixels of individual colors forming images, the solution Lumiode uses LEDs as pixels, which are more efficient by not lose light by filtering.

As explained by the founder and CEO of Lumiode, Vincent Lee, the result will be portable screens and smaller, brighter and more energy-efficient fit with daily activity projectors, but as pointing from Google, it can be difficult to use the projected screen Glass in broad daylight.

LumiodeAmong the challenges of this technology is the battery life and, like screens of smartphones, which use LEDs as a light source behind the screen, images are created when light passes through filters , which in addition to reducing the brightness increases consumption, since the LED must always be on.

The development of Lumiode was performed in the laboratory of Columbia University unconventional Electronics and is based on recording patterns series Led by adding a thin layer of silicone over each to control the amount of light emitted by each LED, so the image component is the LED itself, rather than using it as a backlight.

According to Lee, making this microdisplay is not expensive, employing components and processing techniques standards, and ensures that this technology is "thirty times brighter and ten times more efficient than other display technologies."

Lumiode staffThe largest prototype developed to date by this company has a square millimeter with 50 × 50 LEDs of a single color, while Lee expected to create a prototype of 320 × 240 pixels next year and other colors probably generated by adding a special coating on the chip.

Lumiode said that's when may be associated with electronics manufacturers to incorporate this technology not only for portable microdisplays, but also to project information onto the windshield of a car.

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