Overdriving value generating method

An overdriving value generating method, adapted to a liquid crystal display (LCD), and the overdriving value generating method comprising:

• receiving a current gray value and a previous gray value, wherein the current gray value and the previous gray value commonly correspond to a pixel of the LCD;
• obtaining a first gray reference value and a second gray reference value closed to the current gray value, and a first previous gray reference value and a second previous gray reference value closed to the previous gray value according to a look-up table, and obtaining four first overdriving values according the first gray reference value, the second gray reference value, the first previous gray reference value and the second previous gray reference value, wherein the first gray reference value is the same to the first previous gray reference value, and the second gray reference value is the same to the second previous gray reference value;
• and
• obtaining a target overdriving value corresponding to the current gray value and the previous gray value through a parallelogram interpolation operation according to the current gray value, the previous gray value, the first gray reference value, the second gray reference value, the first previous gray reference value, the second previous gray reference value and the first overdriving values.
