20120081346 | SHIFT REGISTER, DISPLAY-DRIVING CIRCUIT, DISPLAYING PANEL, AND DISPLAYING DEVICE - Provided is a shift register of a display-driving circuit which carries out simultaneous selection of a plurality of signal lines by using a simultaneous selection signal. A stage of the shift register includes (i) a set-reset type 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 of the stage (i) becomes active due to an activation of the simultaneous selection signal and then (ii) remains active while the simultaneous selection is being performed, and the output from the flip-flop is inactive during a period in which a setting signal and a resetting signal are both being active. This makes it possible to quickly carry out the simultaneous selection of all the signal lines and the initialization of the shift register. | 04-05-2012 |

20120086703 | Display Driving Circuit, Display Device And Display Driving Method - A display driving circuit for driving a liquid crystal display panel includes a shift register including a plurality of shift register circuits provided in such a way as to correspond to a plurality of gate lines, respectively, the display driving circuit having latch circuits provided in such a way as to correspond one-by-one to the shift register circuits, a polarity signal being inputted to the latch circuits. When a internal signal generated by a shift register circuit becomes active, a latch circuit loads and retains the polarity signal, and an output from the latch circuit is supplied to a CS bus line. The internal signal becomes active before a first vertical scanning period of a display picture. | 04-12-2012 |
20120105395 | DISPLAY DRIVING CIRCUIT, DISPLAY PANEL AND DISPLAY DEVICE - A stage of the shift register has (i) a set-reset type flip-flop which receives an initialization signal and (ii) a signal generating circuit which receives a simultaneous selection signal and which generates an output signal by use of an output of the flip-flop. In at least one example embodiment, the output of the flip-flop becomes inactive regardless of whether a setting signal and a resetting signal are active or inactive, as long as the initialization signal is active. The initialization signal becomes active before the end of the simultaneous selection, and then becomes inactive after the end of the simultaneous selection. This makes it possible to stabilize operation of the shift register after the end of simultaneous selection of a plurality of signal lines carried out by the display driving circuit at a predetermined timing. | 05-03-2012 |
