The invention discloses a low power consumption control system of an ion displayer and a method thereof and belongs to the technical field of controlling plasma displayers. The low power consumption control system of the ion displayer comprises a row memorizer 1, a row memorizer 2, a row-by-row detection module, an interlaced detection module, a datum judging and selecting module, an array detection module and a datum processing module. The low power consumption control method of the ion displayer comprises the following steps: (1) calculating a row-by-row difference number A, an interlaced difference number B and an adjacency array difference number D, (2) comparing the A with the B and choosing the smaller value to be a row difference number C, and (3) halving the red, green, blue (RGB) data if the row difference number C is larger than a threshold value T4 and the adjacency array difference number D is larger than a threshold value T5. Due to the fact that the method that an addressing period adopts different addressing modes under different display frames is adopted, the low power consumption control system of the ion displayer and the method thereof has the advantages of effectively reducing the display power consumption of a plasma display panel (PDP) and reducing the load current of a high voltage addressing chip.
Description
technical field [0001] The invention relates to a control technology for reducing power consumption of a plasma display, in particular to a low power consumption control technology for a color three-electrode AC plasma display. Background technique [0002] Color alternating current plasma (AC-PDP) is developed based on the basic principle of gas discharge, and the ultraviolet light emitted by gas discharge excites phosphors to emit light to realize display. At present, the three-electrode surface discharge type AC-PDP is the most competitive type of PDP. For this kind of AC-PDP, addressing and display separation (ADS) technology is mostly used to realize grayscale display, that is, a TV field is divided into It is 10 (NTSC system) or 12 (PAL system) sub-fields that emit light successively. Each sub-field is composed of a preparation period, an addressing period and a maintenance period. A 256-level gray scale can be achieved through an appropriate combination of sub-fields ...
