Embodiment Construction

[0038] Certain example embodiments of the invention will now be described in more detail with reference to the accompanying drawings.

[0039] In the following description, the same reference numerals are used for the same elements even in different drawings. The matters defined in the specification, such as detailed construction and elements, are provided to assist in a comprehensive understanding of the present invention. Therefore, it is obvious that the present invention can be carried out without particularly defined matters. Also, well-known functions and constructions are not described in detail since they would obscure the invention with unnecessary detail.

[0040] figure 1 is a block diagram of a plasma display panel (PDP) according to an exemplary embodiment of the present invention.

[0041] The PDP includes a signal processor 10 , a display 30 and an afterimage preventing block 20 .

[0042] The signal processor 10 processes the input video signal using proces...

Abstract

An apparatus of preventing an afterimage of a plasma display panel (PDP) and a method thereof are provided, which includes selecting at least one sub-field to insert an afterimage preventive pattern, among sub-fields of a plurality of frames of a video signal to be displayed, inserting the afterimage preventive pattern to the selected sub-field, and displaying on a display, the frame containing the sub-field in which the afterimage preventive pattern is inserted.

Description

technical field [0001] Apparatus and methods according to the present invention relate to a plasma display panel and a method of preventing afterimage, more particularly, by inserting an afterimage preventing pattern in a sub-field, or otherwise inserting a pattern having an afterimage preventing Patterned subfields to prevent afterimages related to video signal playback. Background technique [0002] A plasma display panel (PDP) includes a plurality of fine phosphors. A PDP includes: two glass plates, each having an arrangement of transparent electrodes; and a gas injected between the glass plates. As a result of applying a voltage to the gas, radiation occurs, ultraviolet rays are generated, and thus the phosphor is excited and emits light. There are generally three phosphor cells: red (R), green (G) and blue (B) cells, and almost the entire color range is achievable. [0003] If a still image is displayed for a long period of time, the phosphors at the divisions of the...
