BLK and the Display Control
Since the IC internal data (D1 to D72 and the control data) is undefined when power is first applied, the display is off (S1
to S24, G1 to G3 = 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 144 bits of serial data from the controller and setting BLK pin high after
the transfer completes while the display is off. (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
