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

FIELD: information technology.

SUBSTANCE: display driving circuit that carries out charge coupled (CC) driving is configured such that retaining circuits (CSL) are provided in such a way as to correspond one-by-one to their respective stages (SR) of a shift register, that a polarity signal CMI is input to each of the latch circuits (CSL), that when an internal signal Mn (CSRn) generated by a shift register (SRn) at the n-th stage becomes active, a latch circuit (CSLn) corresponding to the n-th stage loads and retains the polarity signal CMI, that an output signal SRBOn from the shift register at the n-th stage is supplied as a scanning signal to a gate line (GLn+1) connected to pixels corresponding to the (n+1)th stage, and that an output signal from latch circuit (CSLn) corresponding to the n-th stage is supplied as CSOUTn to a CS bus line forming capacitors with pixel electrodes of pixels corresponding to the n-th stage.

EFFECT: in CC driving, the appearance of transverse stripes in the first frame in which display of a video signal on a display device starts can be eliminated without an increase in circuit area.
