Abstract
AbstractA novel charge pump pixel circuit for reflective display requiring high voltage driving, which is more than 10 V, is proposed for low‐power mobile application. By adopting proposed low‐voltage frame inversion method, we can reduce input data voltage swing to almost half of driving voltage on a pixel electrode, so the power consumption on parasitic elements can be substantially reduced.The operation of the pixel circuit was confirmed through the prototype of 3.6″ polymer dispersed liquid crystal displays and the simulation results show that the proposed approach reduces the power consumption by 64.3%, compared with the conventional driving method.
