DEVICE FOR CONTROLLING LIGHT-EMITTING CRYSTALS IN LED Russian patent published in 2017 - IPC G09G3/14 

FIELD: physics.

SUBSTANCE: invention relates to devices for controlling light-emitting crystals in light-emitting diodes of electronic devices, matrix screens and other visual data display means. Substance of invention consists in that device comprises light-emitting crystals, a comparator module, a counter, pulse generator, register, a decoder, wherein output of register is connected to input of a memory module, output of pulse generator is connected to input of memory module, output of memory module is connected to input of decoder, output of which is connected to input of memory module. Invention provides branching of part of current flowing through light-emitting crystal, proportional to coefficient in memory cell, which provides adjustment of brightness of light-emitting crystal.

EFFECT: simplified circuit for controlling light-emitting crystals in a two-component LED, which leads to unloading of control electronics.
