  • Patent number: 7046216
    Abstract: A plasma display panel that minimizes the power consumption required for driving the PDP is disclosed. A reset pulse of a ramp-down waveform supplied in a reset period goes down to a voltage level higher than a negative scan reference voltage, and is kept for a specified period. Also, a sustain pulse voltage level of a selective erase type sub-field is provided with a voltage level relatively higher than the sustain pulse provided from the selective write type sub-field, or a reset pulse of a ramp-up waveform that goes from a maximum voltage level of the ramp-up waveform down to a ground voltage level or more is supplied to a scan electrode as well as a selective erase scan pulse descends from a predetermined selective erase scan voltage level to the ground level or more. Therefore, the data driving voltage is minimized, and the display state is stabilized.

  • Patent number: 7042553
    Abstract: Disclosed herein is an apparatus for conveying substrates, which is capable of efficiently conveying large substrates and has a function to temporarily store the substrate in a buffer unit. The apparatus includes a substrate support unit, a conveying unit, and the buffer unit. The substrate support unit supports the substrate thereon. The conveying unit sequentially conveys the substrate support unit to a plurality of processing units. The buffer unit is provided at a predetermined portion of the conveying unit to move the substrate support unit upward away from the conveying unit in a vertical direction, thus temporarily storing the substrate support unit therein while spacing the substrate support unit apart from the conveying unit. The substrate conveying apparatus thus efficiently conveys the substrates, regardless of sizes of the substrates, while temporarily storing the substrates to buffer a difference in the processing time.
