The pixel is the minimum unit used to represent or record information in photonic devices.

The size of the pixel determines the density of the integrated information, such as the resolution of displays or cameras.

Most methods used to produce display pixels are based on two-dimensional patterning of light-emitting materials. However, the brightness of the pixels is limited when they are.

They completed the devices by depositing a common quantum dot layer on top of the pre-patterned contacts. “This approach permits straightforward integration of an arbitrary number of complementary p- and n-type transistors into the same quantum dot layer prepared as a continuous, un-patterned film via standard spin-coating,” said Klimov.
