Abstract :
This paper presents hybrid-level charge recycling scheme which can be helpful in implementing low power LCD column drivers. The proposed scheme eliminates the necessity of polarity reversing circuit of the conventional method, simplifying the control. Another technique which merges two external capacitors into one is also described. This makes the multi-level recycling operation in column driving IC more practical
