The microdisplay Leti presented earlier this year at CES Las Vegas was remarkable in two ways. First, its luminance, which is 1,000 times greater than that of current microdisplays, meaning the display remains visible even in bright sunlight. Second, the microdisplay’s 10-micron pixel pitch, which makes it possible to play high-resolution video. The prototype will be used to develop augmented reality glasses that let the wearer see the real environment and superimposed visual information at the same time. The exceptional brightness was achieved by using gallium nitride LEDs, known for their excellent yields. A new hybridization technique, called “microtubes,” was used to power each pixel individually. The research was conducted in conjunction with the III-V Lab and resulted in twelve patents.
