Pixel driving method, timing controller and liquid crystal display

A timing controller, driving at least one pixel in a liquid crystal display, comprising at least one lookup table, wherein:

• the timing controller detects a temperature t of the liquid crystal display;
• the timing controller determines an initial level, and a target level;
• the timing controller looks up a corresponding coefficient an in the lookup table based on the initial level and the target level;
• the timing controller estimates an overdrive level OD by substituting the coefficient an and a function of the temperature f(t) into the formula:

• the timing controller drives a pixel by the overdrive level OD to reach the target level within a frame time.

A liquid crystal display, comprising:

• a panel module, comprising at least one pixel;
• a timing controller, driving the pixel;
• a temperature sensor, coupled to the timing controller, sensing a temperature t of the panel module;
• a memory device, coupled to the timing controller, storing an initial level;
• a lookup table comprising:
• a plurality of columns and rows, defining initial levels and target levels;
• and
• a plurality of coefficients an, each corresponding to an intersection formed by one column and one row;
• wherein:
• the timing controller receives a target level;
• the timing controller looks up a corresponding coefficient an in the lookup table based on the initial level and the target level;
