QuantumFilm Technology[ edit]QuantumFilm Technology involves the creation of a film to coat the image sensors used in a cellphone camera, allowing it to capture more light, improving the quality of the images taken. [9] [10] A typical camera phone pixel sensor is made up of several layers, with a layer of colored plastic or glass acting as a color filter sitting on top of several layers of metal connecting silicon electronic transistors together, which is itself on top of a base layer of silicon used by the sensor's electronic transistors and photodetectors. The light coming to the sensor has to pass through the layers of metal before reaching the silicon, a weak light absorber, so the sensor detects only about 25 percent of the light that makes up the image. [11] QuantumFilm Technology places a layer of semiconducting crystals - called quantum dots - on top of the chip, which allows the chip to absorb more light, place more pixels in a smaller space, and create sharper images. [12]

Using quantum dots is more efficient at capturing light than traditional silicon-based image sensor chips (capturing 90-95% of the light that hits it), giving the sensors higher sensitivity in low light as well as higher resolution. [3] [13] And while traditional image sensors read an image from top to bottom (which can create a blurred image when the subject is moving), quantum dots detect the entire image at the same moment, reducing the chance for distortion. [14]

Invisage holds patents related to the development of QuantumFilm technology, as well as its applications toward optoelectronic devices. [15]
