BLK and the Display Control
Since the LSI internal data (SD1 to SD74 and the control data) is undefined when power is first applied, the display is
off (G1 and G2 = low) by setting the BLK pin low at the same time as power is applied. Then, meaningless display at
power on can be prevented by transferring all 92 bits of serial data from the controller while the display is off and setting
BLK pin high after the transfer completes. (See Figure 3.)
Power Supply Sequence
The following sequences must be observed when power is turned on and off. (See Figure 3)
Power on: Logic block power supply (V
DD
) on
→
Driver block power supply (V
FL
) on
Power off: Driver block power supply (V
FL
) off
→
Logic block power supply (V
