Example Embodiment

[0041] Hereinafter, the present invention will be further described in detail with reference to the examples and drawings, but the implementation of the present invention is not limited thereto.

[0042] Such as figure 2 As shown, a device for controlling the display time of a static picture includes:

[0043] The video code stream input module is used to receive the video code stream output by the video processing module of the plasma display panel and send it to the data extraction module and the pixel processing module; the video code stream includes display data, line synchronization signal stream, and field synchronization signal Flow, clock signal flow;

[0044] The data extraction module is used to remove the line blanking data and vertical blanking data in the display data according to the line synchronization signal flow and the field synchronization signal flow, extract a field of valid display data and encapsulate it into a display data frame, and send it simultaneousl...

Abstract

The invention discloses a device for controlling the displaying time of a static picture and an implementation method thereof. The device comprises a video stream input module, a data extraction module, a frame buffering module, a frame latching module, a comparison module, a control operation module, a pixel processing module and a video stream output module, and the device further comprises a communication module. The invention further discloses an implementation method for the device, which comprises the following steps: initializing the modules; carrying out the frame latching operation on a data-displaying frame; and judging whether the displaying data of the frame buffering module and the frame latching module are consistent, if so, judging whether the displaying time of the static picture exceeds the predetermined threshold, and carrying out the frame-inserting operation or pixel-shifting operation, and if not, re-latching the data frame. By accurately measuring the displaying time of the static picture and carrying out the corresponding avoiding operations, the invention can prevent a plasma display panel from displaying static pictures and high-brightness pictures for a long time, prolongs the service life of the plasma display panel, effectively reduces the remnant shade problems of the plasma display panel and greatly reduces the workload of development.

Description

technical field [0001] The invention relates to the technical field of plasma panel display screens, in particular to a device for controlling the display time of a static screen and its implementation method. Background technique [0002] At present, a plasma display panel has a wide range of applications, and is composed of a video processing module, a plasma display logic module, and a plasma display screen. The video input of the plasma display panel, such as composite video, composite video, digital video, and received wired and wireless video, etc., forms a video code after the video processing module performs operations such as sampling, digitization, video scaling, menu, and switching video sources. flow. [0003] The plasma display logic module is mainly responsible for digitizing the display data in the video code stream output by the video processing module to realize molecular field display. The processing operation of the display data mainly includes separatin...
