Aledia Achieves Monolithic RGB Micro LED Subpixel Breakthrough

Aledia has produced a functional wafer featuring monolithic RGB nanowire micro LED technology. This development marks a significant step in display manufacturing by integrating red, green, and blue subpixels onto a single chip. The company achieved a subpixel pitch of just 2.5 microns through this process. The physical size of each individual pixel measures 5 by 5 microns. This compact pixel density allows for higher resolution outputs without requiring massive screen sizes.

The new micro LED structure supports resolutions up to 8K and 16K on 65-inch and 75-inch models. Aledia claims the technology can reach peak brightness levels of 10,000 nits. The nanowires used in the display have diameters ranging from 100 to 400 nanometers. This monolithic approach eliminates the need for the mass transfer process typically required in micro LED production. Aledia has developed a monolithic RGB nanowire process that eliminates the mass transfer step.

The integration of RGB subpixels directly onto the wafer enables smaller form factors for high-resolution displays. Aledia states that this design reduces power consumption and heat generation compared to traditional methods. The company suggests that these efficiency gains make perfect televisions more feasible. The technology enables higher resolutions such as 8K or 16K in smaller form factors.
