13. APPLICATION NOTE(REFERENCE ONLY)

13.1 Adjust V1 and V4 voltage to keep the V0-V1 = V4-VSS relation to get better display quality. The

(V0-V1)-(V4-VSS) value had better less than 100mV.

13.2 Add 0.1uF high frequency by-pass capacitor to filter the noise on V0~V4 to VSS.

13.3 When OP follower circuit is used, please be sure the OP power is higher than V0 at least 1.5V.

13.4 EIO1 and EIO2 is enable pin for driver, please pay attention to the distance to avoid noise when

cascade function is used. Two chip connecting distance is as shorter as better.
