CONVERTER CIRCUIT AND MONOCHROME PICTURE DISPLAY DEVICE COMPRISING SUCH A CONVERTER CIRCUIT

摘要

To display bivalent color signals in a monochrome picture display device so that the original color remains recognizable by choosing a suitable luminance ratio, and colors having a low brightness are displayed with a sufficient degree of visibility, the combination of a sum signal and a correction signal is formed from the bivalent color signal, wherein the color differences are derived from the sum signal and the correction signal ensures the basic luminance.
