20110193853 | SCANNING SIGNAL LINE DRIVE CIRCUIT, SHIFT REGISTER AND DISPLAY DEVICE - There is provided a display device capable of preventing a malfunction and a display defect due to an off-leak from occurring even when a circuit in a shift register is configured utilizing thin film transistors of relatively large off-leaks. In at least one embodiment, each of bistable circuits that constitute the shift register includes: a thin film transistor for increasing a potential of an output terminal based on a first clock; a thin film transistor for decreasing the potential of the output terminal; a thin film transistor for increasing a potential of a range netA connected to a gate terminal of the thin film transistor based on a start signal; thin film transistors for decreasing the potential of the range netA; a capacitor for increasing the potential of a range netB connected to a gate terminal of the thin film transistor; and a thin film transistor for decreasing the potential of the range netB. | 08-11-2011 |
20110199354 | SCANNING SIGNAL LINE DRIVE CIRCUIT, SHIFT REGISTER, AND DRIVE METHOD OF SHIFT REGISTER - There is realized a scanning signal line drive circuit (in a display device) capable of, even in a case where a circuit in a shift register is formed using a thin-film transistor which is relatively large in off leakage, suppressing unnecessary power consumption due to a leakage current in the thin-film transistor. In at least one embodiment, bistable circuit that forms the shift register includes a thin-film transistor for raising a potential of an output terminal based on a first dock, a region netA connected to a gate terminal of the thin-film transistor, another thin-film transistor for lowering a potential of the region netA, and a region netB connected to a gate terminal of the other thin-film transistor. With this configuration, the potential of the region netB is raised based on a third clock which is advanced in phase by 90 degrees with respect to the first clock and is lowered based on a fourth clock which is delayed in phase by 90 degrees with respect to the first clock. | 08-18-2011 |
20110205194 | DISPLAY DEVICE AND METHOD FOR DRIVING THE SAME - A display device of at least one embodiment of the present invention has a connection changeover circuit, including switch elements for time-division driving, formed on a liquid crystal panel, and the switch elements are paired so that two switch elements in each pair are connected in parallel to one video signal line. The paired switch elements are turned on at the same time, and immediately before one of the switch elements is turned off upon completion of a charging period for its corresponding video signal line, only the other switch element is turned off. As a result, while maintaining drive performance, it is possible to solve the impact of fieldthrough phenomenon caused by one of the switch elements, which are transistors, and also reduce parasitic capacitance formed in the other switch element, thereby suppress the impact of fieldthrough phenomenon caused by that switch element. | 08-25-2011 |

20120146969 | SCANNING SIGNAL LINE DRIVE CIRCUIT AND DISPLAY DEVICE INCLUDING SAME - A gate driver is implemented that includes an easily testable shift register to improve panel yields. In a monolithic gate driver including a shift register that operates based on 4-phase clock signals, each stage of the shift register is provided with an inter-stage connecting wiring line for receiving a clock signal other than clock signals received from a clock signal trunk wiring line, from a different stage than the stage; and a contact that connects a wiring line formed on the stage to the inter-stage connecting wiring line. The shift register is grouped every four consecutive stages. Markings formed of different numbers of planar-view circular-shaped structures are formed on bistable circuits of four stages included in each group such that the same type of marking appears every four stages. | 06-14-2012 |
