Abstract
The present invention relates to a method of compensating for the disturbances due to the demultiplexing of an analogue signal with regard to a circuit comprising N data lines, wherein the demultiplexing is carried out by sample-and-hold circuits whose input receives the analogue signal and whose output is connected to one of the N data lines, the N sample-and-hold circuits being operated in succession by a sampling signal (ECHi). During the application of the sampling signal (ECHi, V) to one of the sample-and-hold circuits, an opposite compensation level (V) which is lower than the level of the sampling signal is applied to the N−1 sample-and-hold circuits. Application in particular to LCD screens.
