Abstract (en)
[origin: FR2857146A1] The device has compensation units with operational amplifiers (11) connected between gate and source electrodes of polycrystalline silicon modulators. The counter reaction of each amplifier compensates threshold trigger voltage of each modulator irrespective of voltage value. Each amplifier has a non-inverse input (+) and an inverse input (-) and an output terminal, where the output is connected to the gate electrode. The non-inverse input (+) is connected to an addressing unit of a column controlling the modulators and the inverse input (-) is connected to the source electrode.
