Los Angeles-based startup Q-Pixel has announced the world’s first ultra-high-resolution, full-color MicroLED display. Through the use of patented polychromatic MicroLEDs, Q-Pixel achieved a full-color LED display with a record density of 5,000 pixels per inch (PPI), surpassing the current world record of 2,000 PPI previously set by Taiwan’s Industrial Technology Research Institute.
Since the invention of the first single-color light-emitting diode (LED), LED technology has become ubiquitous in a variety of electronic devices. It enables the production of bright and energy-efficient displays for modern televisions, smartphones and wearable electronics. However, it is based on composing pixels from multiple LEDs: red, green and blue to create the full spectrum of colors. This physically limits the pixel density.
MicroLED technology (light emitting diodes up to 100 microns) is becoming increasingly popular in the display industry due to its high energy efficiency, faster response time and higher pixel density. However, there are also limitations, since multiple LEDs must be used for a single pixel. The startup Q-Pixel offers a different approach.
Q-Pixel’s patented polychromatic micro-LED technology provides a customizable full color gamut display with a single 4-micron pixel, replacing previous single-color LED pixels. Q-Pixel’s customizable full-color single-pixel LED eliminates the need to assemble a single pixel from LEDs of different colors (a major bottleneck in traditional LED display manufacturing), while still delivering ultra-high pixel density.
“At Q-Pixel, we strive to break the hurdle of high manufacturing costs and greatly simplify the LED display assembly process. Our goal is not only to significantly reduce costs, but also to minimize the number of defective pixels and maximize build speed for high-quality, high-performance, large-area (over 100 inches) foldable microLED displays. In particular, our technology is also fully portable to smaller displays such as mobile phones, tablets, PCs and wearables (smartwatches, AR and VR headsets).”, — noted in Q pixels.
