Fig. 3 shows a son mapping table of first exemplary embodiment according to the present invention.
Suppose in Fig. 3 in order to be easy to explanation, a field has 14 sons (SF1-SF14) and is used to express 512 gray level ranks, and the luminance weights of given the first to the 14 son (SF1-SF14) is respectively 1,2,3,4,6,9,13,19,28,41,62,85,108,131.Also supposition is arranged this 14 weights with incremental order, and the weight of given first son SF1 is 1, and the weight of given the 14 a son SF14 is 31.When expressing gray level 335, can arrive these 14 sons (SF1-SF14) by mapping (enum) data " 00110110101101 ".Here, ' 0 ' representative this discharge cell in corresponding son field is not luminous, and ' 1 ' representative this discharge cell in corresponding sub is luminous.
In addition, the 13 a son SF13 has weight limit for input gray grade 314,315 for example.Thereby when the 13 a son SF13 had weight limit, sub-field data maker 250 had been ignored the data corresponding to first a son SF1.That is, use the second to the 13 son (SF2-SF13) to express input gray grade 314,315 with gray level 314.
In addition, the 14 a son SF14 has weight limit for input gray grade 335,336,337,338 for example.Thereby when the 14 a son SF14 had weight limit, sub-field data maker 250 had been ignored the data corresponding to a SF1, second a son SF2.That is, use the 3rd to the 14 son (SF3-SF14) to express input gray grade 335,336,337,338 with gray level 335.
Summarize speech, in first exemplary embodiment of the present invention, with amounting to M sub-field in N the son (expression input image data of M＜N).In this case, when expressing input image data, corresponding to first the data (wherein, K＞M) can be left in the basket and be disabled to (K-M) son according to the high son to K of using in order of luminance weights.Therefore, can use M son field to express view data, this compares the number that has reduced addressing period with the situation of using N son field to express gray level, has reduced the energy consumption in the addressing period thus.
High when K is expressed view data when using, it is invalid to the data of (K-M) son field to make corresponding to first, but highly express view data representative to K son and express the situation of relative high grade grey level because use, thus when ignoring the data of hanging down weight materially affect gray level not.Thereby, according to first exemplary embodiment of the present invention, be used to express gray level or reduce the profile noise increase the son of number allow mapping and use one a little, prevented that like this energy consumption that is caused by the addressing period that has increased number from increasing.
As mentioned above, the son field that can ignore low weight.In other words, in the present invention's first exemplary embodiment, when using the son field of high weight, distribute to corresponding sub with ' 0 '.But, suppose that the first sub-field data that lists the discharge cell that provides at first row first is valid data ' 1 ', and the first sub-field data that the discharge cell that provides is provided at second row first is an invalid data ' 0 ', then in the addressing period of the first son field, carry out blocked operation applying the discharge cell of addressing voltage, and carry out another blocked operation to apply the discharge cell of non-addressing voltage to second row, first row to first row, first row.Thereby invalid data can produce switching, and because switch energy loss can take place.
To a kind of method that is used to reduce the energy loss that is caused by invalid data be described with reference to figure 4, Fig. 5, Fig. 6, Fig. 7.
Fig. 4 shows the process flow diagram of the invalid data disposal route of second exemplary embodiment according to the present invention, and the hypothesis that Fig. 5 carries out scan operation based on order on column direction shows the valid data of being determined by Fig. 4 method.With reference to figure 4 and Fig. 5, use description to handle method at first sub invalid data of the discharge cell (that is, by i Y electrode Yi and j the discharge cell that addressing electrode Aj forms) that i is capable and j lists.Term " just before (just before) " and " just after (just after) " represent on the temporal meaning " just exist ... before " and " just exist ... afterwards ", term " ... (before) before " and " ... (after) afterwards " comprise respectively and " just existing ... before " and " just exist ... more preceding stage and the time stage after going up afterwards " and on the representative time.
As shown in Figure 4, in order to handle first sub invalid data of the discharge cell that lists at the capable j of i, in step S410, whether the data of the first sub-field of the discharge cell that (i+1) row j that sub-field data maker 250 is determined just to be scanned the discharge cell that the capable j of i lists after list (" just after " discharge cell) are valid data.
When the data of first son of " just after " discharge cell are effective, in step S420, sub-field data maker 250 is put up with in the data of first son (" just before " discharge cell) of the discharge cell that (i-1) row j that is scanned before the discharge cell that the capable j of i lists the lists data with the first sub-field of " just after " discharge cell and is compared.When the data of first son of the data of first son of " just before " discharge cell and " just after " discharge cell were consistent, the data that sub-field data maker 250 is arranged on data and " just before " of the first sub-field of the discharge cell that the capable j of i lists and " just after " discharge cell were identical.Promptly, as shown in Figure 5, at step S431, the invalid data of the first son field of the discharge cell that the capable j of i lists when the data of first son of the data of first son of " just before " discharge cell and " just after " discharge cell are given as ' 0 ' is set to valid data ' 0 '; And in step S432, the invalid data of the first son field of the discharge cell that the capable j of i lists when the data of first son of the data of first son of " just before " discharge cell and " just after " discharge cell are given as ' 1 ' is set to valid data ' 1 '.Thereby, because " just before " and " just after " discharge cell is consistent with the address data (sub-field data) of the first sub-field of the discharge cell that lists at the capable j of i, thus switching do not produced, thus can eliminate the energy loss that causes by switching.
As shown in Figure 5, in step S433, when the data of first son of the data of first son of " just before " discharge cell and " just after " discharge cell were inconsistent, it was valid data that the original invalid data of first son of the discharge cell that sub-field data maker 250 will list at the capable j of i is expressed.In this example, switch, so when expressing invalid data, do not produce switching with raw data because between two contiguous valid data, produce.Promptly can not have to express raw data under the situation of switch cost.
When the data of first son of " just after " discharge cell when being not effective, in step S440 and S410, sub-field data maker 250 orders determine whether the data of the first son field of discharge cell (" afterwards " discharge cell) of scanning the discharge cell that (i+1) row j lists after are effective.Thereby sub-field data maker 250 determines whether the data of first son of " afterwards " discharge cell of listing at (i+2) row j are effective.If for not, then sub-field data maker 250 determines whether the data of first son of " afterwards " discharge cell of listing at (i+3) row j are effective.Can repeat this processing up to finding " afterwards " discharge cell with valid data.When the processing by S440 and S410 find (i+k) row and j list after the data of the first son field of discharge cell when being effective, at step S420, sub-field data maker 250 is compared the data of first son of " just before " discharge cell with the data at first son of (i+k) row and " afterwards " discharge cell of listing of j, and is arranged on the valid data of the first sub-field of the discharge cell that the capable j of i lists then by above-mentioned treatment S 431, S432, S433 according to comparative result.
The method of the invalid data of the first son field that is used to handle the discharge cell that lists at the capable j of i has been described with reference to figure 4, and also can be according to the invalid data of the first and second son fields of handling the discharge cell that lists at the capable j of i with reference to figure 4 described methods.
View data is mapped on the son, and compares in proper order so that valid data to be set thus according to the data of the method for describing with reference to figure 4 and Fig. 5 with invalid data and " just before " and " just after " discharge cell.Summarize speech, when adopting first to k to shine upon view data corresponding to discharge cell, then handle as invalid data to (K-M) sub-field data first.In this case, first each invalid data in (K-M) sub-field data is to determine by the corresponding sub-field data that has the discharge cell of initial valid data among " just before " discharge cell and " just after " discharge cell.Thereby, according to second exemplary embodiment of the present invention, do not ignore invalid data but the data of invalid data and " just before " and " just after " discharge cell are compared with the minimizing energy consumption.
Fig. 6 and Fig. 7 show the invalid data disposal route of carrying out supposition the 3rd exemplary embodiment according to the present invention of scan operation based on order on column direction respectively.The method of the invalid data of the first son field that is used to handle the discharge cell that lists at the capable j of i will be described with reference to figure 6.
When the data of first son of " just before " discharge cell when being given as " 0 ", the invalid data ' 0 ' that sub-field data maker 250 maintains the discharge cell that the capable j of i lists is valid data ' 0 '.Because " just before " discharge cell is consistent with first sub address data (sub-field data) of the discharge cell that the capable j of i lists, so not owing to invalid data switches, and since address data be given as ' so 0 ' do not have the address discharge generation.
When the data of first son of " just before " discharge cell when being given as ' 1 ', the valid data ' 1 ' that sub-field data maker 250 maintains the discharge cell that the capable j of i lists are valid data ' 1 '.Can as given, express raw data, thereby can not take place by the energy loss that switching causes.
When the data of first son of " just before " discharge cell when being given as ' 0 ', the invalid data ' 1 ' of the discharge cell that sub-field data maker 250 will list at the capable j of i is treated to valid data ' 0 '.Then can eliminate by the energy loss of switching and address discharge causes.
When the data of first son of " just before " discharge cell when being given as ' 1 ', the invalid data ' 0 ' that sub-field data maker 250 maintains the discharge cell that the capable j of i lists is valid data ' 0 '.In this case, the energy loss that is caused by switching takes place, so but owing to do not provide address discharge can eliminate the energy loss that is caused by address discharge.In a similar fashion, view data is mapped on the son field, and the data of invalid data with " just before " discharge cell are compared in proper order.
With reference to figure 7, use description to handle the method for first and second sub invalid data of the discharge cell that lists at the capable j of i.
That is, will be applied to the first and second son fields with reference to the method that figure 6 provides.For example, when the data of first and second sons of " just before " discharge cell are given as ' 01 ' and the data of first and second sons of discharge cell to be processed when being given as ' 00 ' as invalid data, invalid data is set to ' 00 ' as described in reference to Figure 6.When the data of first and second sons of " just before " discharge cell are given as ' 11 ' and the data of first and second sons of discharge cell to be processed when being given as ' 10 ' as invalid data, invalid data is set to ' 10 '.
According to the 3rd exemplary embodiment of the present invention, do not ignore invalid data, but its data with " just before " discharge cell are compared to reduce energy consumption.
Very clear for a person skilled in the art, can carry out various modifications and change to the present invention under the conditions without departing from the spirit and scope of the present invention.Thereby, this invention is intended to cover those and fall into claims and interior modification of the present invention and the change of equivalent scope thereof.
