Q-Pixel announces the world’s smallest full-color pixel (1 micro-meter size) and achieves 10,000 PPI resolution microLED displays

November 29, 2023 (Los Angeles, California)—US startup Q-Pixel Inc. has announced a new breakthrough in engineering full-color, ultra-high resolution microLED (light emitting diode) displays. 

Q-Pixel has developed the world’s smallest full-color pixel and demonstrated it in the first ever 10,000 PPI, full-color microLED display (surpassing Q-Pixel’s previous world-record 5000 PPI full-color display, announced in May 2023). 10,000 PPI resolution has previously been exhibited only in monochromatic, single-color displays. However, for the first time, Q-Pixel has successfully achieved 10,000 PPI resolution in full color using their proprietary tunable polychromatic light emitting diode (TP-LED). Because it can emit the full range of visible light within a tiny pixel, TP-LED is the enabling technology that promises to drive microLED display technology to new limits. 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 micron. 

MicroLED 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 microLED 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 AR/VR devices.  Q-Pixel’s latest achievement showcasing the world’s smallest full-color pixel and 10000 PPI full-color display are significant technological milestones that highlight the considerable advantages of TP-LED pixel technology over RGB microLED subpixels and promise to lead the way to future generations of exceptional displays.

Q-Pixel joins Silicon Catalyst Semiconductor Incubator to Accelerate MicroLED Display Development

Los Angeles, CA & Silicon Valley, CA, November 15, 2023 - Q-Pixel, a microLED display innovator, has joined Silicon Catalyst, the world’s only incubator focused exclusively on accelerating early-stage semiconductor hardware companies, to accelerate Q-Pixel's development of their full-color displays manufactured with tunable polychromatic LEDs.

Q-Pixel has developed a single LED pixel that can be tuned across the full color spectrum rather than requiring three pixels (red, green, and blue) to achieve full color. This breakthrough enables Q-Pixel's displays to deliver higher resolution and more brightness with less power consumption and lower cost. Earlier this year, Q-Pixel demonstrated the highest microLED density in the world. Q-Pixel's technology promises to revolutionize the high-resolution display industry for screen sizes ranging from personal (smartphones and wearable devices) to large (greater than 100 inch).


The Silicon Catalyst ecosystem, which includes a comprehensive coalition of in-kind and strategic partners that dramatically reduce the cost of development along with a network of experienced advisors that coach and connect startup entrepreneurs, helps early-stage semiconductor hardware companies address the challenges of moving from idea to realization while simultaneously de-risking the companies for investors.

J.C. Chen, co-founder and CEO of Q-Pixel, commented, “Q-Pixel is delighted to join Silicon Catalyst as a Portfolio Company. We expect their extensive ecosystem will help us engage with customers and build a profitable business around our technology.” 

“I’m very pleased to welcome Q-Pixel into Silicon Catalyst," stated Nick Kepler, Silicon Catalyst COO, "We are impressed with the company’s vision and progress. Our comprehensive ecosystem of Advisors, Strategic and In-Kind Partners, and investors look forward to helping them on their journey to deliver innovative products to their target markets."

Q-Pixel Inc., a Los-Angeles based stealth startup, announces the world's first full-color, ultra-high resolution microLED display, establishing a groundbreaking new milestone in the display industry. For the first time, using their proprietary Polychromatic microLED technology, Q-Pixel has achieved full-color LED display with a world record-breaking pixel density of 5000 pixels per inch (PPI), surpassing the current world record of 2000 PPI held by ITRI of Taiwan. Q-Pixel's revolutionary new technology is a game-changer to the display industry.

Since the invention of the first single color light emitting diode (LED), LED technology has since become ubiquitous in most electronic applications. In particular, in the display industry, it allows the bright, energy-efficient displays seen in today's televisions, smartphones, and wearable electronics. MicroLED displays are the sought-after Holy Grail of the display industry due to their high energy efficiency, faster response time, and higher pixel density. However, in the last two decades, full-color LED pixel density and display resolution have not seen much improvement. This is largely due to the manufacturing constraint of assembling individual red, green, and blue LEDs to achieve full-color gamut.

Q-Pixel's proprietary Polychromatic microLED technology introduces full-color tunability across a single 4-micron pixel, replacing the century-old single-color LED and addressing several decades-long challenges to the microdisplay industry. Q-Pixel's tunable, full-color single-pixel LED eliminates the need for pick-and-place (a key bottleneck in traditional LED display assembly), while at the same time enabling ultra-high pixel density.
