The Russian electronic industry is the last twenty years rapidly developed,from clumsy monochrome CRTs to the huge LCD displays of the Su-35. I know the Russians are working on the following generation of digital avionics (see MAKS 2019) company's like KRET or Ramenskoye are developing these new avionics. I read at some sites that they use matrix made by South Korea, I can't imagine that the Russians dido not produce or developed their own matrixes. Does someone have information about possible Russian matrix technology?
