Over-driving apparatus, storage method thereof, and display device using the same

A display device, comprising:

• a first substrate;
• a second substrate, disposed opposite to the first substrate;
• a first polarizer, disposed on an external surface of the first substrate;
• a second polarizer, disposed on an external surface of the second substrate, wherein a polarization direction of the first polarizer is parallel to a polarization direction of the second polarizer;
• and
• an over-driving apparatus, comprising:
• a pixel information processing unit, configured to receive a color information of the pixel, the pixel information processing unit electrically coupled to the liquid crystal display;
• a first storage unit, configured to store pixel grayscale values;
• a second storage unit, configured to store a difference value of the pixel grayscale values stored in the first storage unit;
• and
• an over-driving correspondence selection unit, separately electrically coupled to the pixel information processing unit, the first storage unit, and the second storage unit, and configured to select, according to the color information, received by the pixel information processing unit, of the pixel, whether the pixel grayscale values of the pixel need to correspond to the first storage unit or the second storage unit, wherein the over-driving apparatus is disposed on the first substrate or on the second substrate;
• wherein the over-driving correspondence selection unit further comprises:
• a querying and comparing unit, configured to determine, through query and comparison, whether the pixel should obtain data from the first storage unit to perform over-driving or obtain data from the second storage unit to perform over-driving;
• wherein the pixel grayscale values stored in the first storage unit are fixed values;
• wherein the difference value stored in the second storage unit and of the pixel grayscale values stored in the first storage unit is a variable value.
