Patent number: 7525530Abstract: Each of a gate driver and a source driver periodically receives a clock signal and a start pulse, where the start pulse has a certain width and is shifted as shift data in the gate driver or source driver in synchronism with the clock signal. A logic circuit composed of an NAND gate and an inverter receives the start pulse and the shift data, the shift data being the output that is supplied after a predetermined delay from the last stage with respect to the shift direction. The output of the inverter is used to test scanning circuits. This provides a display device and a scanning circuit testing method, which enable the scanning circuits to be judged both surely and quickly, without increasing the area or complexity of the circuit.Type: GrantFiled: May 5, 2005Date of Patent: April 28, 2009Assignee: Sharp Kabushiki KaishaInventors: Yutaka Takafuji, Katsunori Shirai, Akira Shibazaki

Publication number: 20090102597Abstract: In a variable resistance element having a variable resistor between first and second electrodes and changing its electric resistance when a voltage pulse is applied between both electrodes, data holding characteristics can be improved by increasing a programming voltage and programming in a high current density. Therefore, a booster circuit for supplying a high voltage is needed when the variable resistance element is applied to a nonvolatile memory. When the smaller of the areas of the contact regions between the first electrode and variable resistor and between the second electrode and variable resistor is set to the electrode area of the variable resistance element, it is set within a specific range not larger than the predetermined electrode area. Thereby the programming current density can be increased without raising the programming voltage, and the variable resistance element having preferable data holding characteristics even at a high temperature can be provided.Type: ApplicationFiled: July 5, 2006Publication date: April 23, 2009Applicant: SHARP KABUSHIKI KAISHAInventor: Kazuya Ishihara
