  • Patent number: 6340960
    Abstract: Circuit and method for driving a plasma display panel, the method including the steps of (1) applying first scan pulses to a first driving block, which is any one of the driving blocks, in every given driving cycle starting from a first scan electrode line to (n)th scan electrode line in succession, and (2) applying second scan pulses each having a given application time difference from the application time of the first scan pulse to a second driving block adjacent to the first driving block starting from (m)th scan line to a first scan line in a reverse sequence to the first scan pulses, whereby preventing an occurrence of flicker because interfaces between driving blocks are continuous with respect to and providing a PDP having a resolution better than an HDTV because intervals of scan pulse application to adjacent lines are short.

  • Patent number: 6288693
    Abstract: Provided is a method of driving a plasma display panel, which is a sub-field driving method for the plasma display panel with scan and addressing drive signals, including the steps of: a) dividing scan lines of a field into at least two areas, and scanning the areas; b) displaying a sub-field by applying different address pulses to the respective areas during the scanning; and c) repeating the preceding steps to drive the sub-field, thereby displaying the field.

  • Patent number: 6198476
    Abstract: A method of and system for driving a plasma display panel (PDP), which is designed to increase the amount of data processed in unit time. The method includes the steps of dividing row electrodes into at least two groups, splitting the field, and applying driving pulses to each split field with a phase difference. Also, the present invention uses a lower bit preceding scanning method where the bits of a digital picture signal are aggregated by bits of a kind from the most significant bit to the least significant bit and divided into a plurality of pairs of upper and lower bits as (lower bit, upper bit), the lower bit in each pair of bits being successively scanned, followed by a scanning of the upper bit in each pair of bits. Thus, the efficiency of the AC PDP is enhanced with the reduction in the time needed to construct the field, and readily driving a field even when the amount of data to be scanned is increased.

  • Patent number: 5914563
    Abstract: It is the main objective of the present invention to provide a plasma display panel designed to use a common electronic device, wherein a large size screen of the plasma display panel is divided by maintaining a stable discharge state of each cell and decreasing the data amount of the operating circuits in which the divided screens are operated in parallel simultaneously. To accomplish the above objective, a plasma display panel is provided having a common electrode, a scanning electrode, and a data electrode being disposed between an upper substrate and a lower substrate. The common electrode is arranged parallel to the scanning electrode, and the data electrode is arranged perpendicular to the common electrode and the scanning electrode. A cell is at the intersection where the common electrode and the scanning electrode intersect with the data electrode. The data electrode is divided for the purpose of dividing the plasma display panel into plural screens.
