摘要： With the new plasma display panel technology new kinds of artifacts can occur in video pictures due to the principle that brightness control is done with a modulation of small lighting pulses in a number of periods called sub-fields. These artifacts are commonly described as ‘dynamic false contour effect’. A technique called bit line repeat coding has been developed for reducing the false contour effect. According to this technique sub-field coding is done with common (CSF) and normal sub-fields (SF) where for the common sub-fields (CSF) identical entries in the sub-field code words of two or more corresponding pixels on two or more pixel lines are used. In this specific sub-field coding method some cases will occur in which an error has to be made due to the reduced flexibility in encoding produced by the need to have the same code on common sub-fields (CSF). The general idea of the invention is now to put the coding failures on the higher video levels of the two or more pixels being grouped together. Further improvements concern picture content analysis and or motion detection for controlling the switching between different sub-field coding modes and a specific adapted dithering pattern for use with bit line repeat coding.

摘要： A method of driving a plasma display panel and an apparatus thereof wherein a switching frequency of a data drive IC is reduced to decrease power consumption required for an addressing operation. In the method and apparatus, a plurality of write sub-fields at which a writing data for turning on a cell is subject to a binary coding and a plurality of erase sub-fields for expressing a gray scale value while turning off a desired cell with respect to the cells having been turned on the previous sub-fields including said write sub-fields are established. An erase data having a logic value for turning off the cells is mapped on erase sub-fields, the number of which is smaller than that of said erase sub-fields. A data having a second logic value different from a logical value of said erase data is mapped onto the remaining erase sub-fields other than the erase sub-field on which said erase data has been mapped.

摘要： A display panel driving method sequentially writes pixel data of every display line into pixel cells on display lines belonging to a region other than a black display region on a screen, while the method stops writing pixel data into pixel cells on display lines belonging to the black display region or simultaneously sets the pixel cells into a non-light emitting cell state. Since a time spent for each pixel data writing process in one field is reduced, a light emission period (number of times) allocated to each light emission sustain process is increased, or the number of subfields is increased by the reduction in time, thereby making it possible to improve the quality of a displayed image.

摘要： A method for driving a plasma display panel is deviced to produce a high-quality image with an increased number of gradations. In each subfield, first and second picture element data write processes are executed for writing picture element data in each discharge cell belonging to first and second display areas of the plasma display panel. In addition, first and second light emission sustaining processes are executed for emitting discharge cells in the light emitting state out of the discharge cells belonging to the first and second display areas. In this process, in subfields with less weight among the subfields, the first light emission sustaining process is executed immediately after the completion of the first picture element data write process, the second picture element data write process is executed immediately after the completion of the first light emission sustaining process, and the second light emission sustaining process is executed immediately after the completion of the second picture element data write process.
