Abstract (en)
[origin: EP1622120A1] The device has an operational amplifier (35) with a non-inverted input connected to an output (42) of a current generator (36) for forming, with a gate of a current modulator (26), a negative feedback loop of the amplifier, when one of light transmitters (22-24) is selected. A reference voltage generator (38) provides reference voltage to an inverted input of the amplifier specific to each column or group of columns of the transmitters. An independent claim is also included for a control method for an active matrix image display device.
