Abstract
In a method of dynamic charge sharing for a display device, it is determined whether a current line of a data driver has polarity inverted from a preceding line. Charge sharing is performed globally, if it is determined that the current line is polarity inverted from the preceding line. It is further determined whether the current line and the preceding line are substantially different, if it is determined that the current line is not polarity inverted from the preceding line. Charge sharing is performed in groups if it is determined that the current line and the preceding line are substantially different; otherwise, no charge sharing is performed.
Claims7
A method of dynamic charge sharing for a display device, comprising:
- determining whether pixel data corresponding to a current line to be outputted from channels of a data driver have polarity inverted from a preceding line outputted from the channels;
- performing charge sharing globally for all the channels, if it is determined that the current line is polarity inverted from the preceding line;
- determining whether pixel data corresponding to the current line to be outputted from the channels are substantially different from pixel data of the preceding line, if it is determined that the current line is not polarity inverted from the preceding line;
- and
- performing charge sharing in groups, if it is determined that the current line and the preceding line are substantially different;
- otherwise, no charge sharing is performed.
