    • The present invention relates to a power generation apparatus, and more particularly to a power generation apparatus that generates power by dropping collected water. A power generation apparatus according to an embodiment of the present invention includes: a chamber having an accommodation space for accommodating water, and configured to accommodate water introduced through an intake pipe disposed on the bottom surface thereof; a pressure pump configured to discharge the air of the accommodation space out of the chamber through a discharge pipe provided on the ceiling surface of the chamber by generating pressure; a spray unit provided on the side surface of the chamber, and configured to spray water, introduced by the pressure pump and accommodated in the accommodation space, out of the chamber; and a power generation unit configured to generate power using the pressure of water sprayed by the spray unit.

    • Disclosed herein is a plasma display panel in which afterimage is improved. The plasma display panel according to the present invention includes a panel unit having an upper plate and a lower plate, a frame that supports circuitry, and a conductive material formed between the panel unit and the frame. As such, a conductive material is formed on a bottom surface of a lower plate of a panel. Thus, charges introduced into the lower plate are properly controlled to improve the waveform stability of the panel. Also, a charge characteristic is improved to implement a stable operation. Accordingly, an afterimage time can be reduced. Further, a sheet of a low hardness and light weight is used. It is thus possible to absorb shock and noise of a PDP, accomplish light weight of the PDP and reduce the materials of the sheet.
    • 这里公开了等离子体显示面板,其中余像被改善。 根据本发明的等离子体显示面板包括具有上板和下板的面板单元,支撑电路的框架和形成在面板单元和框架之间的导电材料。 因此,导电材料形成在面板的下板的底表面上。 因此,适当地控制引入下板的电荷,以提高面板的波形稳定性。 此外,改善了充电特性以实现稳定的操作。 因此,可以减少余像时间。 此外,使用低硬度和重量轻的片材。 因此可以吸收PDP的冲击和噪音,实现PDP的重量轻并且减少片材的材料。
