Capacitor split wait time
Note 1
tVWAIT 100 ms
Notes 1. This is the wait time from when voltage bucking is started (VLCON = 1) until display is enabled (LCDON = 1).
2. This is a capacitor that is connected between voltage pins used to drive the LCD.
C1: A capacitor connected between CAPH and CAPL
C2: A capacitor connected between V
L1 and GND
C3: A capacitor connected between V
L2 and GND
C4: A capacitor connected between VL4 and GND
