One Step Closer to the Perfect TV: Aledia Successfully Implements RGB Micro LED Subpixels in a Single Piece
The micro LED TVs we've been waiting for may be closer than ever.
There's no doubt that we all want to have a micro LED TV at home. However, due to the massive size and high cost that this technology currently offers, it's not practical for most people. However, several companies are solving these two problems year after year through new technological competition, and we are getting closer to the perfect TV than ever before. Today is one of those days.
This is because Aledia, a French company, has found a way to solve one of the chronic problems of micro LED technology: the costly 'mass transfer' process. Until now, each pixel required tiny red, blue, and green diodes to be individually placed one by one, which was a major factor in raising manufacturing costs. However, Aledia has succeeded in manufacturing a wafer that includes these three tiny diodes in a single piece. Now it's just a matter of mounting it directly onto the pixel.
Perfect Micro LED TV Becomes Reality: Aledia Successfully Manufactures Monolithic RGB Piece
While news announced about micro LED TVs this year may appear definitive each time, we must understand that this is not isolated progress but parallel advancement. Some focus on improving energy efficiency, some work on reducing pixel pitch, and some like today's announcement are focused on dramatically reducing the manufacturing costs of micro LED TVs. The progress Aledia has achieved today is enormous. This is because we can now end the tedious and expensive mass transfer process.
To understand why this is important, we need to know how micro LED TVs are manufactured. Like OLED, these TVs achieve infinite contrast ratio and perfect blacks. This is because each pixel is made up of tiny red, green, and blue diodes. Until now, these had to go through a 'mass transfer' process that placed them individually. Aledia changed the rules of the game by creating a single wafer (piece) that already contains three tiny diodes and can be mounted directly to a TV. It's much easier and cheaper than before.
To do this, they developed nanowire technology. Through this technology, they implemented a 'monolithic' process that allows red, green, and blue light-emitting bodies to grow simultaneously from a single wafer in just one manufacturing process. This eliminated the need to transfer tens of millions of components to form more than 8,300,000 pixels in a 4K panel. According to the company, they achieved this by adjusting the diameter of the nanowires between 100nm and 400nm within the same production cycle to emit different colors.
Finally Seeing Small and Clear 4K Micro LED TVs, and Reduced Power Consumption and Heat Generation
This French company's progress has brought more improvements beyond just reducing manufacturing costs. Aledia has demonstrated that the subpixel pitch is only 2.5 micrometers, which means the entire pixel size is 5 x 5 micrometers. In other words, since the pixel pitch—the physical spacing between pixels—has become much smaller, it no longer means we need to create monstrously huge TVs to accommodate these components. In addition, by increasing clarity and resolution, it's now possible to implement 8K or 16K panels even in 65-inch or 75-inch models.
Another essential point to note is that this is not theoretical progress on paper. This French brand has announced that it has already successfully manufactured the first functional wafer with excellent results. This means the technology is completely viable and will be the direction micro LED TVs will take in the future.
In conclusion, the 'perfect' TV will be released soon, and it will be micro LED. A TV that is much cheaper than current micro LED, features a fully modular design that can be sized according to user preferences, and has excellent energy efficiency and low heat generation. Starting from 65 inches in size, with overwhelming resolutions like 8K or 16K, maintaining perfect black levels and infinite contrast ratio, and even achieving peak brightness of 10,000 nits, all at an 'affordable' price. Could there be anything better than this?
