Abstract:
1. A method for driving a liquid crystal display (LCD) panel, comprising: A: setting an M*M over drive (OD) table by regarding N grey scales as one unit, the M*M OD table comprises a grey scale value XN*a of a previous-frame image, a grey scale value XN*b of a current-frame image, and an OD value (XN*a, XN*b) corresponding to the grey scale value XN*a and the grey scale value XN*b, wherein a and bε[0, M], N and M are integers, and N>=2; B: regarding x′ as the grey scale value of the previous-frame image and y′ as the grey scale value of the current-frame image when the LCD panel is driven, finding out an effective OD value (x′, y′) from the OD table; if x′ is equal to XN*a, and y′ is equal to XN*b, the effective OD value (x′, y′) is directly found out from the OD table; if x′ is not equal to XN*a, and y′ is not equal to XN*b, a three-dimensional coordinate system is set according to coordinate axis of x′, y′, and the OD value (x′, y′); the OD value (x′, y′) is fitted to a continuous two-dimensional surface by reference to the OD value (XN*a, XN*b) in the OD table, and the OD value (x′, y′) is correspondingly calculated according to function of the two-dimensional surface fitted; and C: outputting the OD value (x′, y′) to the LCD panel after the previous-frame image is output but before the current frame image is output.
