摘要： In a gate driving circuit and a display apparatus, the gate driving circuit comprises a plurality of stages. At least one of the stages comprises a pull-up section responsive to a first node signal; a pull-down section responsive to a second input signal; a discharging section discharging the first node signal in response to the second input signal; a first holding section responsive to the first clock signal, maintaining the first node signal at the off-voltage; and a second holding section responsive to the second clock signal, maintaining the first node signal at the off-voltage. The second holding section has a greater transistor width-to-length ratio than the first holding section. Therefore, an abnormal gate-on signal is less likely to occur, reducing driving defects of the display apparatus.

摘要： A gate drive portion for a display device including multiple pixels having first and second sub-pixels includes a first shift register generating a first output signal in response to a first gate clock signal, a second shift register generating a second output signal in response to a second gate clock signal, a level shifter coupled to the first and second shift registers and amplifying the first and second output signals, and an output buffer coupled to the level shifter and generating first and second gate signals. The first gate signal is generated in synchronization with the first gate clock signal and the second gate signal is generated in synchronization with the second gate clock signal. Accordingly, the charging time of the first and second sub-pixels may be improved by separately driving the odd-numbered and even-numbered sub-pixels and the visibility of the LCD device may also be improved.

摘要： An amorphous-silicon thin film transistor and a shift register shift having the amorphous-silicon TFT include a first conductive region, a second conductive region and a third conductive region. The first conductive region is formed on a first plane spaced apart from a substrate by a first distance. The second conductive region is formed on a second plane spaced apart from the substrate by a second distance. The second conductive region includes a body conductive region and two hand conductive regions elongated from both ends of the body conductive region to form an LI-shape. The third conductive region is formed on the second plane. The third conductive region includes an elongated portion. The elongated portion is disposed between the two hand conductive regions of the second conductive region. The amorphous-silicon TFT and the shift register having the amorphous TFT reduce a parasitic capacitance between the gate electrode and drain electrode.

摘要： A lamp driving device includes a power supplying part and a feedback detection part. The power supplying part provides a plurality of lamps electrically connected in parallel to each other with power. The feedback detection part receives current that flows via the lamps to provide the power supplying part with a feedback signal that prevents the power supplying part from providing normal lamps with power, when at least one of the lamps are abnormal. Although one power supply provides all lamps with power, when at least one of the lamps is abnormal, then whole circuit is opened. Thus, excess current does not flow via remaining lamps that are normal. Thus, a life span of the lamps is not reduced, and a lamp driving device is safe.
