Abstract
A method of driving pixels of a liquid crystal display, a pixel driving device, and a liquid crystal display having the same are provided. The liquid crystal display includes a liquid crystal panel and a pixel driving device, wherein the pixel driving device selectively outputs driving signals having different polarity permutations based on the structure of the display units in the liquid crystal panel.
Claims12
A pixel driving device, comprising:
- a polarity signal generator outputting a first polarity signal based on a first polarity permutation;
- a polarity selector accepting the first polarity signal, a second polarity signal corresponding to a second polarity permutation, and a conversion signal and then selectively outputting the first polarity signal or the second polarity signal based on the conversion signal;
- and
- a driving signal generator electrically connected to the polarity selector to accept the first polarity signal or the second polarity signal;
- wherein the driving signal generator outputs a plurality of first driving signals based on the first polarity permutation after receiving the first polarity signal or outputs a plurality of second driving signals based on the second polarity permutation after receiving the second polarity signal, the first driving signals and the second driving signals correspond to different polarity permutations.
