Segment Display and Annunciator Display
The
HD66705U
provides both segment display, which is driven by the multiplexing method, and annunciator
display, which is driven statically. Annunciator display is driven at a logic operating voltage (V
CC
–
AGND) and is thus also available while the LCD drive power supply is turned off. Accordingly,
annunciator display is suitable for displaying marks during system standby, when it is desirable to reduce
current consumption. It is available in sleep mode, where internal multiplexing operations for character or
segment display are halted. If an alternating signal is supplied to the EXM pin, it is also available in
standby mode, where the internal R-C oscillator is halted. Here, AGND must be equal to or above the GND
level.
Note that annunciator display cannot share character display drivers SEG and COM but require special
drivers ASEG and ACOM that require long routing.
Tables 21 to 23 illustrates segment display and annunciator display.
