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.

摘要:
Disclosed are a hinge assembly and a mobile device having the hinge assembly. In the mobile device, a rotation portion 14 slides and rotates on a base portion 10, so as to be inclined to the base portion 10. For this reason, the rotation portion 14 is connected to the base portion by means of the hinge assembly 20 so as to slide and rotate on the base portion 10. The rotation portion 14 slides on the base portion by a predetermined distance, and then rotates to be inclined at a desired angle with respect to the base portion 10. The rotation portion 14 easily rotates with respect to the base portion of the mobile device, so that the status of the mobile device can be easily converted. Further, when the status of the mobile device is converted, the front, rear, left and right of a display screen is not changed. As a result, the mobile device should not have a structure of changing a display direction of the display screen. Further, there is an advantage in that an electric connection between the base portion and the rotation portion by means of a connection link mechanism can be stably achieved.
