  • Publication number: 20140132495
    Abstract: Disclosed is a gate printed circuit board, a connector-free liquid crystal display (LCD) panel assembly, a driving-signal timing module included in the liquid crystal display (LCD) panel assembly, and a method of driving the liquid crystal display (LCD) panel assembly. According to the present invention, since a separate connector and a gate printed circuit board of a conventional LCD panel is not required for applying a gate-driving signal generated from an external information processing device, a thickness and the number of parts of the LCD device is reduced. Further, when the gate-driving signal is transmitted through the TFT substrate, the voltage Voff for maintaining a thin-film transistor (TFT) in a turned-off state is modified so that users may not recognize the imbalance in brightness.

  • Patent number: 7473996
    Abstract: A signal transfer film includes a base film, a lead line formed on the base film and a passivation layer protecting the lead line. The passivation layer includes a nonlinear edge portion formed at a boundary region between the lead line and the passivation layer. The nonlinear edge portion of the passivation layer disperses a stress concentrated to the boundary region in various directions when the base film is bent. Thus, the signal transfer film may prevent breaking of the lead line, thereby enhancing yield thereof.

  • Patent number: 6840198
    Abstract: An air-proportionality type boiler is provided. Since the air-proportionality type boiler directly controls a current proportionality gas valve according to an amount of air by using a low-price AC air blower, a low-price current proportionality gas valve and a low-price airflow sensor, a gas supply amount can be adjusted with respect to all ranges of the airflow amount. Also, an appropriate calorie required for proportionally controlling a present circulation water temperature to a set temperature, can be supplied. The boiler can be safely ignited to perform a combustion operation under the optimal condition although abnormal weathers and conditions. Accordingly, since a combustion performance is enhanced, combustion efficiency is high and a fuel cost can be saved.
