DISPLAY DRIVING CIRCUIT, DISPLAY DEVICE AND DISPLAY DRIVING METHOD Russian patent published in 2013 - IPC G09G3/36 

FIELD: physics.

SUBSTANCE: display driving circuit, designed to drive a liquid crystal display panel, having bus lines (CS), includes a shift register (gate line driving circuit), which includes a plurality of shift register (SR) circuits so as to correspond to a plurality of gate lines, respectively, a display driving circuit, having latch circuits (CSL) so as to correspond, one after the other, to shift register (SR) circuits, wherein a polarity signal (CMI) is fed into the latch circuits (CSL). When an internal signal (Mn), which is generated by shift register circuits (SRn), becomes active, the latch circuit (CSLn) corresponding to that shift register circuit loads and holds the polarity signal (CMI) and the output signal (CSOUTn) and the latch circuit (CSLn) is fed to the bus line (CS) as a CS signal. The internal signal (Mn), which is generated by shift register circuits (SRn), becomes active before the first period of vertical scanning of the display picture.

EFFECT: high quality of display when switching on power without increasing the area of the circuit.
