Q-Pixel develops smallest full-color pixel and demonstrates first 10,000PPI full-color micro-LED display
Q-Pixel Inc of Los Angeles, CA, USA has developed what it claims is the world’s smallest full-color pixel and demonstrated it in the first ever 10,000PPI, full-color micro-LED display (surpassing the firm’s previous record 5000PPI full-color display, announced in May).
Resolution of 10,000PPI has previously been exhibited only in monochromatic, single-color displays. However, for the first time, Q-Pixel has achieved 10,000PPI resolution in full color using its proprietary tunable polychromatic light-emitting diode (TP-LED), which can emit the full range of visible light within a single pixel. Using TP-LED, Q-Pixel now has the unique capability of fabricating extremely small, fully color-tunable single pixels with diameters as small as 1 μm.

Micro-LED technology offers several key benefits over existing OLED and LCD display technologies, notably, longer lifetime, superior brightness and energy efficiency. However, the complex, costly and labor-intensive process of assembling full-color micro-LED displays using monochromatic red, green and blue (RGB) LED subpixels remains a major barrier to both high-resolution displays and commercially viable displays. Ultra-high-resolution, full-color displays are especially sought after for near-eye applications, such as those used in augmented-reality/virtual-reality (AR/VR) devices.
Q-Pixel reckons that showcasing the smallest full-color pixel and 10000PPI full-color display highlights the advantages of TP-LED pixel technology over RGB micro-LED subpixels.
The results were presented in the TechBlick event ‘Mini- & Micro-LED Displays: Markets, Manufacturing Innovations, Applications, Promising Start-ups’ on 29–30 November.
