Document Type and Number:
Japanese Patent JP5467562
Kind Code:
B2
Abstract:
A regulating circuit for driving a display screen pixel having a light-emitting diode includes at least one operational amplifier (11) having a first input (12), a second input (13), and an output (16). A measuring signal (Umess) dependent on the flow of current through a driver transistor of the light-emitting diode is applicable to the first input (12) and a network (15, 15′) consisting of active and/or passive components and at least one capacitor (C) is connected to the second input (13). The network (15, 15′) has a plurality of inputs (U1-Un). A digital reference input signal is applicable to the plurality of inputs (U1-Un), and the output (16) of the operational amplifier (11) is connected to a data line of the pixel.
