Description
Technical field
The present invention relates to a kind of control technology that reduces the plasma display power consumption, especially a kind of low power consumption control technology of colored three electrode AC plasma display.
Background technology
The ultimate principle development that chromatic alternating-current plasma (AC-PDP) is based on gas discharge realizes showing by the ultraviolet excitation light-emitting phosphor that gas discharge sends.At present, three-electrode surface discharge type AC-PDP is the most competitive a kind of PDP type, mostly adopt addressing (ADS) technology of separating with demonstration to realize what gray scale showed for this AC-PDP, be about to a TV Field and be divided into successively luminous 10 (TSC-system formula) or 12 (pal mode) subfields, each subfield is by the preparatory stage, address period and maintenance phase form, just can realize that by suitable subfield combination 256 grades gray scale shows, be illustrated in figure 1 as the time span distribution situation in one of the TSC-system formula, the preparatory stage time span of each subfield approaches, the address period time consistency, the maintenance phase time span satisfies certain proportionate relationship.
The addressing mode of address period is divided into two kinds, line by line addressing: each subfield begins to the last delegation of addressing from the first row of PDP, the control signal waveform of the high pressure addressing chip of address period PDP as shown in Figure 2, each subfield address period high level only has one section, expression addressing all row; Interlacing addressing: the odd-numbered line of each addressing PDP of subfield elder generation, the even number line of addressing PDP again, address period PDP high pressure addressing chip controls signal waveform as shown in Figure 3, each subfield address period high level is divided into two sections, first paragraph represents the addressing of odd-numbered line, and second segment represents the addressing of even number line.
Addressing mode is different, and the data-signal of high pressure addressing chip output is also different, thereby causes the demonstration power consumption of PDP also different.Take display frame shown in Figure 4 as example, the data-signal high-low level change frequency that data-signal high-low level change frequency is compared when adopting line by line addressing when adopting the interlacing addressing is little, thereby the demonstration power consumption of interlacing addressing is less, and the load current of high pressure addressing chip is less simultaneously; Display frame shown in Figure 5, the data-signal high-low level change frequency that data-signal high-low level change frequency is compared when adopting the interlacing addressing when adopting line by line addressing is little, thereby the demonstration power consumption of addressing is less line by line, and the load current of high pressure addressing chip is less simultaneously.

Wherein the interlacing detection module for statistics every delegation's difference number, if the current behavior odd-numbered line then with the RGB data reading of line storage 1, and compares with the RGB data of current line; If the current behavior even number line, then with the RGB data reading of line storage 2, and with the RGB data of current line relatively; If the difference value Y2 after relatively is larger than threshold value T2 for the RGB data of some pixels, then counter S2 adds 1, and all satisfy the number of pixels B of this condition in the TV Field until count;
Wherein data are judged selection module selection output addressing mode and row difference number, receive the adjacent lines difference number A of the output of detection module line by line and the output of interlacing detection module behind the difference number B of delegation, A and B are compared, little such as line by line difference number A, then export line by line addressing indicator signal, row difference number C is defined as value A line by line, and is little such as the difference number B of interlacing, then export interlacing addressing indicator signal, row difference number C is defined as the value B of interlacing;
Wherein the row detection module is statistics adjacent columns difference number, with the RGB data of the RGB data of a pixel on the buffer memory and the current pixel difference value after relatively, if this difference value is larger than threshold value T3, then counter S3 adds 1, and all satisfy the number of pixels D of this condition in the TV Field until count;
Data processing module wherein, receiving data judge to select to compare behind the capable difference number C of module output and the row difference number D that the row detection module is exported, if C is larger than threshold value T4 for row difference number, and D is larger than threshold value T5 for row difference number, then to the processing that reduces by half of RDB data, be zero with half of full frame sub-pixel RGB data according to the staggered assignment of the odd even subfield in the odd even TV occasion.
Owing to having adopted 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 being statistics adjacent lines difference number line by line, the interlacing detection module is mainly used in as adding up every delegation's difference number, data are judged selection module selection output addressing mode and row difference number, the row detection module is statistics adjacent columns difference number, and data processing module is to the data processing that reduces by half.Whole control system can be by under the different display frame, can effectively reduce the demonstration power consumption of PDP, reduce the load current of high pressure addressing chip, under the prerequisite that does not affect display effect, further reduce the subfield data for the part special frame simultaneously, reduce power consumption and load current, thereby improve the reliability of PDP.The power-consumption control system of ion display of the present invention can be applied to control on the master chip of plasma display apparatus driving circuit, also can be applied to the product that other has similar principles, and is applied widely.
The power-consumption control system of ion display of the present invention, wherein data processing module is to the processing that reduces by half of RGB data, if C is larger than threshold value T4 for row difference number, and D is larger than threshold value T5 for row difference number, be zero with half of full frame sub-pixel RGB data according to the staggered assignment of the odd even subfield in the odd even TV occasion then, namely an interior odd number sub-pixel corresponding to odd number subfield of TV Field does not show, even sub-pixel normally shows, even sub-pixel corresponding to even number subfield do not show, the odd number sub-pixel normally shows; Even sub-pixel corresponding to odd number subfield in the next TV Field do not show, the odd number sub-pixel normally shows, odd number sub-pixel corresponding to even number subfield do not show, even sub-pixel normally shows; Use simultaneously other subfield to keep pulse weight look-up table and subfield Map Searching table.
Owing to having adopted above-mentioned control system, wherein data processing module is to the data processing that reduces by half, C is larger than threshold value T4 when row difference number, and D is larger than threshold value T5 for row difference number, the data-signal high-low level change frequency that the output of high pressure addressing chip is described is larger, current loading is larger, for not affecting the performance of addressing chip, be zero with half of full frame sub-pixel RGB data according to the staggered assignment of the odd even subfield in the odd even TV occasion then, allow half of full frame sub-pixel not show, thereby reduce the change frequency of data-signal high-low level, because the integrating function of human eye, display frame can not be affected substantially.Under the prerequisite that does not affect display effect, further reduce the subfield data for the part special frame, reduce power consumption and load current, thereby improve the reliability of PDP.
The power consumption control method of ion display of the present invention, realize by following steps:
Step 1, calculate the difference value Y1 of the same location of pixels corresponding data of adjacent lines, and with threshold value T1 relatively, if larger than threshold value T1, then count an effective difference value Y1, be labeled as A after add up the number of effective difference value Y1 of interior all row of a TV Field;
