Q-Pixel announces 1µm full-colour pixel
US start-up demonstrates full colour microLED display with 10,000 PPI resolution
US startup Q-Pixel has developed what it believes is the world’s smallest full-colour pixel and demonstrated it in the first ever 10,000 PPI, full-colour microLED display. This surpasses Q-Pixel’s previous 5000 PPI full-colour display, announced in May 2023.
The technology behind Q-Pixel's breakthrough is its proprietary tuneable polychromatic LED (TP-LED) which can emit the full range of visible light within a single pixel. Q-Pixel says that using TP-LED, it can now make full colour tuneable, single pixels with diameters as small as 1 micron.
MicroLED technology offers several benefits over existing OLED and LCD displays, notably, longer lifetime, superior brightness and energy efficiency. However, the complex, costly process of assembling full colour microLED displays using red, green, and blue LED subpixels remains a barrier to both high resolution displays and commercially viable displays.
Q-Pixel says its technology offers key advantages in this respect and has the promise to lead the way to future generations of displays, especially for near-eye applications, such as those used in AR/VR devices.
