  • Patent number: 7525530
    Abstract: 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.

  • Publication number: 20090085892
    Abstract: There is provided an input device using a touch panel allowing input operations to be performed without viewing an input surface. The input device includes a transparent capacitance-type touch panel (12) formed in the shape of a dome, and a liquid crystal panel (14a) disposed on the back side of the touch panel. The position detection processing portion (20) applies predetermined voltage to four terminals (T1 to T4) of the touch panel, and detects current flowing via each terminal to detect the coordinates of a point on the touch panel operated by the operator's finger (100) based on the detected current value. The data processing portion (30) causes a liquid crystal display device (14) to display an operation screen, including graphics, symbols, etc.
