Note:
1. Indicates the resistance between one pin from Y1 to Y160 and another pin from V1L/V1R,
V2L/V2R, V3L/V3R, V4L/V4R when load current is applied to the Y pin; defined under the
following conditions:
V_CC–V_EE = 28V
V1L/V1R, V3L/V3R = V_CC – 2/10 (V_CC–V_EE)
V4L/V4R, V2L/V2R = V_EE + 2/10 (V_CC–V_EE)
V1L/V1R and V3L/V3R should be near the V_CC level, and V2L/V2R and V4L/V4R should be near
the V_EE level. All voltage must be within ÆV. ÆV is the range within which R_ON, the LCD drive
circuits’ output impedance, is stable. Note that ÆV depends on power supply voltage V_CC–V_EE.
