Wherein data processing module, receive after data judge the row difference number D selecting the row difference number C of module output and row detection module to export and compare, if number C is larger than threshold value T4 for row difference, and row difference number D is larger than threshold value T5, then reducing by half process to RDB data, is zero by the half of full frame sub-pixel RGB data according to the assignment of interlocking of the odd even subfield in odd even TV occasion.
Owing to have employed above-mentioned control system, wherein line storage 1 and line storage 2 are the storage element of storage two row RGB data; Detection module is mainly used in as statistics adjacent lines difference number line by line, interlacing detection module is mainly used in as statistics is every a line difference number, data judge to select model choice to export addressing mode and row difference number, row detection module is statistics adjacent column difference number, and data processing module to reduce by half process to data.Whole control system is by under different display frame, effectively can reduce the display power consumption of PDP, reduce the load current of high pressure addressing chip, under the prerequisite not affecting display effect, reduce sub-fields data for part special frame further simultaneously, reduce power consumption and load current, thus improve the reliability of PDP.The power-consumption control system of ion display of the present invention, can be applied on the master chip of control plasma display apparatus driving circuit, also can be applied to the product that other has similar principles, applied widely.
The power-consumption control system of ion display of the present invention, wherein data processing module to reduce by half process to RGB data, if number C is larger than threshold value T4 for row difference, and row difference number D is larger than threshold value T5, be then zero by the half of full frame sub-pixel RGB data according to the assignment of interlocking of the odd even subfield in odd even TV occasion, odd number sub-pixel corresponding to the odd number subfield namely in a TV Field does not show, even sub-pixel normally shows, even sub-pixel corresponding to even number subfield does not show, and odd number sub-pixel normally shows; Even sub-pixel corresponding to the odd number subfield in next TV Field does not show, and odd number sub-pixel normally shows, and odd number sub-pixel corresponding to even number subfield does not show, and even sub-pixel normally shows; Use other subfield to maintain pulse weight look-up table and subfield Map Searching table simultaneously.
Owing to have employed above-mentioned control system, wherein data processing module to reduce by half process to data, when row difference number C is larger than threshold value T4, and row difference number D is larger than threshold value T5, illustrate that the data-signal low and high level change frequency that high pressure addressing chip exports is larger, current loading is larger, for not affecting the performance of addressing chip, be then zero by the half of full frame sub-pixel RGB data according to the assignment of interlocking of the odd even subfield in odd even TV occasion, the half of full frame sub-pixel is allowed not show, thus reduce the change frequency of data-signal low and high level, due to the integrating function of human eye, display frame can not be affected substantially.Under the prerequisite not affecting display effect, reduce sub-fields data for part special frame further, reduce power consumption and load current, thus improve the reliability of PDP.
The power consumption control method of ion display of the present invention, is realized by following steps:
Step 1, calculate the difference value Y1 of the same location of pixels corresponding data of adjacent lines, and compare with threshold value T1, if larger than threshold value T1, then count an effective difference value Y1, after adding up the number of effective difference value Y1 of all row in a TV Field, be labeled as A;
