Low power driving system and timing controller for display device

A low power driving system for a display device, comprising:

• a timing controller configured to receive packet data for correcting a polarity of line data correct polarities of previous line data and current line data based on the packet data, divide a display pattern into a static pattern and a dynamic pattern based on a difference between the previous line data and the current line data, and transmit a packet to which one of first option information corresponding to the static pattern and second option information corresponding to the dynamic pattern is applied;
• and
• a source driver configured to receive the packet and perform a low power mode corresponding to the static pattern based on the first option information or adaptive charge sharing corresponding to the dynamic pattern based on the second option information,
• wherein the timing controller is further configured to:
• calculate a power gain quantity and power loss quantity attributable to charge sharing for the current line data based on a result of a comparison between the previous line data and the current line data, and
• provide the second option information on whether to apply charge sharing to the current line data based on a result of a comparison between the power gain quantity and the power loss quantity.
