This article reports that control system designers frequently encounter size and complexity constraints when developing control panels for sophisticated products. With the programmable D880 graphic LCD module, Irvine, California-based C. Itoh & Co. Ltd.'s Electronic Component Division, hopes to bridge the gap between intimidating arrays of standard switches and expensive CRT interfaces. The switches combine a low-power, super-twist LCD screen with a custom IC driver and multicolor backlighting. Red, green, or amber backlights allow the indication of special conditions. Red or green is obtained by reversing the polarity of the 5V applied to the LED.
