ABSTRACT:
Circuits are provided for determining the use of a flat panel display such as a liquid crystal display or a plasma display based on a plurality of input conditions. A switch circuit is provided for cutting off the supply of display driving power to the flat panel display unit when the display unit is not in use. Gate circuits are provided for locking a LCD driving signal to a non-driven level when the non-use of the LCD is determined. A display controller controlling the display of a CRT display unit includes a display data conversion table and a plurality of D/A converters. A circuit is provided for inhibiting the supplement of clock pulses to a display data conversion table, when a display auto off is enabled. Circuits are provided for cutting off the reference current of the display signal output to the D/A converters.
