13. Resistance between terminal X and terminal V (one of V1L, V1R, V2L, V2R, V5L, V5R, V6L, and
V6R) when load current flows through one of the terminals X1 to X64. This value is specified
under the following conditions:
V_CC–V_EE = 10V
V1L = V1R, V6L = V6R = V_CC – 1/7 (V_CC–V_EE)
V2L = V2R, V5L = V5R = V_EE + 1/7 (V_CC–V_EE)

The following is a description of the range of power supply voltage for liquid crystal display drive.
Apply positive voltage to V1L = V1R and V6L = V6R and negative voltage to V2L = V2R and V5L
= V5R within the ∆V range. This range allows stable impedance on driver output (RON). Notice
that ∆V depends on power supply voltage V_CC–V_EE.
