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
