LIGHT-EMITTING DIODE Russian patent published in 2017 - IPC H05B37/02 

FIELD: information technology.

SUBSTANCE: light-emitting diode relates to information equipment and lighting engineering so that, for example, it can be used in design of large-size matrix screens and other visual data display facilities. Light-emitting diode comprises on substrate along with light-emitting diode chips unit for controlling radiation of crystals, one input is connected to the anode terminal, the other input is connected to the cathode terminal, and the outputs are connected to transistor bases, wherein the collectors of transistors are connected to cathodes of light-emitting crystals, anodes of which are connected to each other and connected to the anode terminal, herewith the emitters of transistors are connected to each other and connected to the cathode terminal.

EFFECT: invention provides the possibility of controlling selected light-emitting diode crystal by two external contacts (anode and cathode).
