Instruction Setup: Reference
(1) Initialization
Note: With this IC, when the power is applied, LCD driving non-selective potentials V
pin) are output through the LCD driving output pins SEG and COM. When electric charge is remaining in the smoothing
capacitor connecting between the LCD driving voltage output pins (V
become totally dark instantaneously when the power is turned on. To avoid occurrence of such a failure, we recommend the
following flow when turning on the power.
