Abstract:
Circuit and method for controlling a liquid crystal segment (1) display wherein the shape of the control signals of the segments (e1, e2, b1, b2) is adapted according to a supply voltage (Vdd) so as to compensate at least partially the opacity variations caused by the supply voltage variations.
