Driving method for liquid crystal device

A driving method for a liquid crystal device of the type comprising:

• a pair of substrates, a liquid crystal disposed between the substrates so as to form a matrix of pixels arranged in a plurality of rows and a plurality of columns, an electrode matrix for applying voltages to the liquid crystal at respective pixels, and a plurality of active elements each provided to a pixel for supplying a voltage applied to the liquid crystal at the pixel;
• the driving method comprising driving the liquid crystal device in a succession of frame periods each designed for displaying one picture frame data,
• wherein each frame period is divided into a plurality of sub-frame periods including at least one preceding sub-frame period and a final sub-frame period so that said at least one preceding sub-frame period provides a total period which is shorter than the final sub-frame period,
• the active elements along the rows of pixels are sequentially selected row by row at respective selection periods in each sub-frame period so that a total of the selection period(s) for an active element at each pixel in said at least one preceding sub-frame period is shorter than the selection period for the active element at the pixel in the final sub-frame period, and
• the liquid crystal at each pixel is sandwiched between a pair of electrodes formed on the pair of substrates, and the liquid crystal is supplied with a voltage in the one or more preceding sub-frame period, which voltage is lower than a voltage applied to the pair of electrodes in the selection period(s) of the one or more preceding sub-frame period in each frame period.
