QuantumFilm developer receives $17million in Series D

A Securities and Exchange Commission filing dated March 25, 2014, revealed that InVisage Technologies Inc., developer of a quantum-dot based film material intended to improve light capture in image sensors, has raised $17,832,709 out of a total equity offering of $30million.

In February, the company announced it had received a Series D round of venture funding led by GGV Capital and including Nokia Growth Partners who joined existing investors RockPort Capital, InterWest Partners, Intel Capital and OnPoint Technologies.

InVisage said it would use the Series D money to begin manufacturing its QuantumFilm image sensors, which are being evaluated by phone manufacturers.

QuantumFilm is the world's most light-sensitive image sensor for smartphones, InVisage claims. The company's approach is to add a layer of quantum dot film to conventional CMOS image sensors. The increased sensitivity provides more headroom for sensor design and improves photographs in low light conditions.

From capturing light and turning signals from each pixel into digital information to rendering these signals into tuned-up images, traditional image sensors use silicon semiconductor technology. But silicon was never designed to capture light; it is an uneven absorber of visible light. InVisage then developed the QuantumFilm, whose thickness is measured in nanometres, to absorb 100 per cent of the light seen by the naked eyes.

Sony and TSMC are also into optimisation of image sensors. See the story here.

"The participation of new investors, including a major handset maker, in this round signals that imaging is a critical differentiator in mobile devices," said Jess Lee, CEO of InVisage Technologies, in a statement.

InVisage made the news recently by producing a promotional video described as an introduction to the company's product but did so while deriding the communication skills of engineers.
