POL
I Polarity select for the dot-inversion control. Available at the rising edge of LD
“POL” value is latched at the rising edge of “LD” to control the polarity of the even or
odd outputs. “POL=1” represents that the next-line odd outputs are of positive
polarity with a voltage output range from V1~V5, and even outputs are of negative
polarity with a voltage output range from V6 to V10. On the other hand, if LD gets
low level “POL”, odd outputs are of negative polarity and even outputs are of
positive.
POL=1: Odd outputs range from V1 ~ V5
Even outputs range from V6 ~ V10
POL=0: Odd outputs range from V6 ~ V10
Even outputs range from V1 ~ V5
*Remark: Pay attention to the polarity when selecting the 300-channel function.
The polarity of OUT160 ~OUT309 must be changed. (The polarity needs to
be continuous, +, -, +, -, +, -, etc. If you don’t change the polarity, it will not be
continuous between OUT150 and OUT160 when selecting the 300-channel
function. )
