A control circuit (50, 150) for a liquid display device (60) has LCD drivers (61, 62) incorporating respective memories and a programmable controller (70, 170) operatively connected between the drivers and an external microprocessor (100) across an external interface (11). The device may incorporate a transparent touch panel (80) overlying the display device (60). The interface (11) comprises intelligent serial and/or parallel connections incorporating data, control and clock lines. A device incorporating the control circuit has "sleep", "idle" and "active" modes, the drivers (61, 62) operating in the "idle" mode. |
