Abstract (en)
[origin: WO2006114132A1] The invention relates to a circuit and method for controlling a liquid crystal segment (1) display in which the shape of control signals of the segments (e1, e2, b1, b2) is adapted according to a supply voltage (VDD) in such a way that the opacity variations caused by the supply voltage variations are at least partially compensated.
