Q-Pixel launches Q-Transfer technology for micro-LED manufacturing
Micro-LED display startup Q-Pixel Inc of Los Angeles, CA, USA has debuted Q-Transfer technology, which directly addresses the pixel transfer challenge long faced by the micro-LED display industry.
The low yield of conventional mass transfer processes (<99.99%) leads to prohibitively high repair and manufacturing costs and remains a major barrier for scaling micro-LED displays towards mass production. As a result, only limited high-end micro-LED products are currently available on the market.
Q-Transfer is said to radically improve micro-LED transfer yield while maintaining high resolution and alignment accuracy, enabling the production of large-area high-quality micro-LED displays, used for wearables, mobile devices, and transparent displays, at affordable prices.
By implementing its patented Q-Transfer process, Q-Pixel has demonstrated color display prototypes using its tunable polychromatic micro-LEDs (TP-microLEDs). These displays consist of 10μm pixels at over 500 pixel per inch (PPI) densities and, most notably, zero missing pixels in the transfer process for > 99.9995% transfer yield — more than an order-of-magnitude improvement over existing transfer approaches.

“Q-Pixel’s patented Q-Transfer process revolutionizes micro-LED manufacturing, providing a simple, cost-effective approach for the display industry to achieve future generations of displays,” comments Nick Kepler, chief operating officer of semiconductor incubator Silicon Catalyst. “Q-Transfer unlocks the potential of micro-LEDs to break into display markets beyond just the AR/VR market, enabling a launch into the wider market of smartwatches, smartphones and other large-area devices,” he adds.
“Q-Pixel has made astounding progress since joining the Silicon Catalyst Ventures portfolio,” notes Dr Shih-Wei Sun, founding managing director of Silicon Catalyst Venture Fund, and former CEO of United Microelectronics Corp (UMC). “Q-Pixel continues to push the known boundaries of display technology with their impressive results, and we strongly support Q-Pixel’s vision of delivering next-generation display products,” he adds.
“The debut of our Q-Transfer display technology marks a new milestone in Q-Pixel’s micro-LED display technology portfolio,” says Q-Pixel’s Dr J. C. Chen, CEO & co-founder. “Q-Pixel’s technical achievements include world records for highest-resolution color active-matrix display (6800PPI), highest-resolution full-color display (10000PPI), and world’s smallest full-color pixel (1μm) diameter.”
