DISPLAY DEVICE Russian patent published in 2013 - IPC G09G3/30 

FIELD: information technology.

SUBSTANCE: display device has (i) pixels, (ii) signal conductors (Sj) and (iii) an operational amplifier (OP1) whose non-inverting input is connected to corresponding signal conductors (Sj). The operational amplifier (OP1) is made such that: the non-inverting input is connected to the output (OUT) through a first impedance element (R1), and the inverting input is connected to the output (OUT) through a second impedance element (R2) and to the reference voltage lead through a third impedance element (Cn). The value Zn of total impedance of pixels electrically connected to corresponding signal conductors, obtained when transmitting a video signal to a corresponding signal conductor and pixels, can be expressed in the form |Zn|<|Z1|-|Z3|/|Z2|, where Z1, Z2, and Z3 denote impedance values of the three impedance elements Rl, R2 and Cn, respectively.

EFFECT: making a display device with low power consumption, enabling fast compensation of spurious capacitance charge.
