Note: *2 The following relations between elements should be maintained: VDD ≥ V1 > V2 > V5 > VEE. VDD – V2 ≤ 7 V, V5 – VEE ≤ 7 V.
*3 When the power supply is turned on, power to the LCD drive is turned on after or simultaneously with the turning on of the logic section’s power
supply. When the power supply is turned off, the logic power supply is turned off after or at the same time the LCD driver power supply is turned off.
