"Invisage CEO Jess Lee stated that Sony is likely to become a Invisage
partner to make the first mass production Quantum film stacked sensors in
2016. The sensors will be first used on smartphones because one of the main
advantages of the new tech is the much thinner sensor. But the new tech
could be used on larger Digital Camera sensors too because of the higher
performance. Quantum Film sensor tech explained via Wikipedia:
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]" | h******c
