14. V1L/R and V6L/R should be near the VCC level, and V5L/R and V2L/R should be near the VEE
level. All these voltage pairs should be separated by less than ∆V, which is the range within
which RON, the LCD drive circuits’ output impedance is stable. Note that ∆V depend on power
supply voltages VCC–VEE. See Figure 21.
