Claim:
A method for gray level dynamic switching, applied to a display with a pixel, comprising the following steps: providing a gray level sequence SG, wherein SG sequentially represents two or more desired gray levels G o (1), . . . , G o (T) of the pixel at consecutive time frames 1, . . . , T and comprises a current gray level G o (t) and a previous gray level G o (t−1) corresponding to time frames t and t−1, respectively, and G o (t) corresponds to a driving voltage V o (t) to present G o (t) under a static condition; and determining an optimized driving voltage V d (t), according to an equation V d ( t )=V o ( t− 1)+ ODV, wherein the ODV is a minimum voltage capable of obtaining one gray level transition in a determined response time; determining a dynamic gray level data G d (t) according to an equation V d ( t )= a×G d ( t ) 3 +b×G d ( t ) 2 +c×G d ( t )+ d; producing the optimized driving voltage V d (t) according to the dynamic gray level data G d (t); driving the pixel with the optimized driving voltage V d (t) to change the pixel forward to a state corresponding to G o (t).
