LED MATRIX Russian patent published in 2017 - IPC H01L33/56 

FIELD: information technology.

SUBSTANCE: led matrix relates to information technology and can be used in designing of large-size matrix screens and other visual information display facilities. Led matrix comprises a light-emitting crystals of different colours, which are installed directly on the conductors of the printed circuit board so, in order to generate uniformly located groups of crystals of different colours – pixels, wherein in the entire area of printed circuit board protective coating, homogeneous over the entire area, is formed, made of resilient translucent epoxy compound, fully covering all light-emitting crystals.

EFFECT: invention provides elimination of distortions of the displayed visual information and enables the required contrast, as well as highly efficient heat removal from the crystal, which significantly increases service life of the led matrix.
