Abstract
A flicker-eliminating method and apparatus for a plasma display panel that is capable of eliminating a flicker phenomenon caused by a different maximum light-emission time. In the method and apparatus, at least two modes in which at least one of said brightness weighting value and the number of said sub-fields are different from each other are established. The sub-field given by the maximum brightness weighting value is arranged at an initial part of the frame in each of said modes.
Claims6
In a method of driving a plasma display panel in which an image of one frame is divided into a plurality of sub-fields each given by a brightness weighting values for its display, a flicker-eliminating method comprising steps of:
- setting at least two modes in which at least one of said brightness weighting value and the number of said sub-fields are different from each other;
- and
- arranging said sub-field given by the maximum brightness weighting value at an initial part of the frame in each of said modes.
In a driving apparatus for a plasma display panel in which an image of one frame is divided into a plurality of sub-fields each given by a brightness weighting values for its display, a flicker-eliminating apparatus comprising:
- a sub-field mapping unit for mapping an input data using at least two modes in which at least one of said brightness weighting value and the number of said sub-fields are different from each other and said sub-field given by the maximum brightness weighting value is arranged at an initial part of the frame;
- and
- said plasma display panel for displaying a data supplied from the sub-field mapping unit.
