Abstract (en)
[origin: WO2007014953A1] An active matrix for a liquid crystal display device comprises pixel electrodes arranged according to a cross grating of rows and columns. Associated to each electrode pixel, an electronic control device is provided that has a first switching element (T) connected between the pixel electrode (Ep<SUB>i,j</SUB>) and an associated column (col<SUB>j</SUB>), a control electrode (g) of the first switching element (T) being connected to an associated line (r<SUB>i</SUB>). The control device comprises an initialization circuit for said pixel electrode comprising a second switching element (T'), connected to the pixel electrode (EP<SUB>i,j</SUB>) and of which a control electrode (g') is connected to a preceding row (r<SUB>i-1</SUB>) of the grating. The invention is for use in active matrix bistable nematic displays.
