SHIFT REGISTER, DISPLAY DRIVING CIRCUIT, DISPLAY PANEL AND DISPLAY DEVICE Russian patent published in 2014 - IPC G09G3/36 G02F1/133 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to a shift register and different types of display driving circuits. The shift register of a display driving circuit carries out simultaneous selection of a plurality of signal lines using a simultaneous selection signal (AONB-signal). A stage of the shift register includes (i) an RS flip-flop and (ii) a signal generating circuit which generates an output signal of the stage by selectively outputting a signal in response to an output of the flip-flop. The output signal (e.g., OUTn signal) of the stage (i) becomes active due to activation of the simultaneous selection signal and then (ii) remains active while the simultaneous selection is being performed, and the output (Qn signal) from the flip-flop is inactive (Low) during a period in which a setting signal (SBn) and a resetting signal (Rn) are both active. This makes it possible to quickly carry out the simultaneous selection of all signal lines and the initialisation of the shift register.

EFFECT: providing fast (i) simultaneous selection of multiple signal lines and (ii) initialisation of the shift register.
