Abstract
FPD（FPD）The development of technology, the especially prevalence of In Cell touch screen designs technique, stern challenge is proposed for full panel design tool.With the increase and the increase of panel size of resolution ratio, the electric capacity that the high-precision electric capacity extracting method based on numerical analysis directly applies to full panel domain calculates very time-consuming, and speed cannot meet design requirement.This paper presents a kind of full panel domain electric capacity rapid extracting method based on array, using domain array features, by array area and non-array Division, non-array Division is extracted, array area array element is extracted and final capacitor combination computational methods accelerate the extraction of full panel domain electric capacity, is solved because full panel domain electric capacity extracted and excessively take or even infeasible problem caused by figure is complicated and scale is excessive.
Description
Technical field
Full panel domain electric capacity rapid extraction based on array is a kind of method that full panel electric capacity is extracted, the invention belongs to
EDA design fields.
Background technology
With FPD（FPD）The fast development of technology, the especially stream of In Cell touch screen designs technique
OK, the electric capacity for full panel domain is extracted and proposes very big challenge to FPD design tools.In order to improve computational accuracy, electric capacity is carried
Instrument is taken generally using the numerical analysis method solved based on field, speed is slow.And with the raising of resolution ratio, design size
Increase, the scale of full panel domain is increasing, while figure complexity also more and more higher.So for full panel domain
Electric capacity is extracted, and conventional method takes very much, and speed cannot meet design requirement.On the other hand, the computational accuracy of domain electric capacity
The overall performance of FPD panels is directly influenced, therefore carry out full panel domain fast and accurately electric capacity to extract is FPD design works
A vital technology in tool.This method is mainly based upon reusable array, it is proposed that a kind of quickly to full panel
The method that domain carries out electric capacity extraction.
In full panel design, it will usually use hierarchy type method for designing, i.e., will first be touched as unit pixel unit and unit
Screen unit is designed, and pixel cell and touch screen unit then are made into array.Domain can be formed by stacking by various exemplary arrays,
Although each exemplary array is array structure, all array superpositions can cause to lose array rule.Need by domain
Domain is processed as reason the domain of reusable array again（Only include and do not overlapped between two-layer hierarchical structure and example）.For so
Reusable array domain, it becomes possible to the feature repeated using figure in array on domain, large-scale full panel electric capacity is carried
Take and be converted into a small number of single repetitive patterns of calculating, then the intermediate result of calculating is combined obtains the electric capacity of final full panel and carry
Result is taken, calculating speed can be thus greatly improved.Set forth herein method will exactly enter for this reusable array domain
A kind of method that row flying capacitance is extracted.
The content of the invention
The present invention proposes a kind of full panel electric capacity rapid extracting method of reusable array domain for simple structure, this
The method of kind carries out subregion to the region shared by the gauze to be extracted first, is divided into array area and non-array area, secondly to non-battle array
Row area carries out division extraction, obtains intermediate result, and then array area is analyzed and extracted again, obtains intermediate result, finally
Two parts intermediate result is combined according to certain requirement, the final electric capacity result of current gauze is obtained.To explain in detail herein
State gauze subregion, the extraction of non-array Division, array area extraction, the method for combination producing final result.
Gauze partition method：All arrays and non-array example of gauze process are obtained first, and record gauze process
The index position (x, y) of array, is recorded as (0,0) for non-array example.Calculating so for the net capacitance can
To be divided into the part of array area and the part in non-array area.As shown in figure 1, gauze B is by non-array area 4,6,7 and array area
5, the index of array area is (0,1), (1,1), (2,1).
Non-array Division extracting method：For the non-array area that extracted gauze is passed through, carried out according to area size first
Divide, obtain the region that size properly ensures precision again, the region for putting forward gauze process then being chosen in all of dividing regions,
Electric capacity extraction is carried out successively, obtains intermediate result.As shown in Fig. 2 gauze B is in non-array area, 5 parts are divided into, are designated as 1,
2,3,4,5, wherein 1st, 3,5 area there are B gauzes to pass through, so needs are extracted, obtain intermediate result Cap1 (B, A), Cap1
(B, C), Cap3(B, A), Cap3(B, C), Cap5(B, C)。
Array area extracting method：For all of array element, if it belongs to certain array reality that composition puies forward gauze process
Example, then extract, and record intermediate result to it.As shown in figure 3, the array element X of the exemplary array that gauze B passes through, it
Inside gauze be m and n, the result extracted to it is CapX (m, n).
Combination producing final result method：The final capacitance of carried gauze is the non-array area and array area that the gauze passes through
Summation, non-thread barrier can directly add up, and the electric capacity for array area is, it is necessary to by the array element for finding it
The relation of the corresponding outside actual gauze of portion's gauze is obtained.As shown in Figure 4, although it is (0,1), (1,1), (2,1) to index
The array element of exemplary array is X, but the corresponding outside gauze of m and n in X be it is different, respectively Cap (B, D)=
CapX(m, n), Cap(B, E) = CapX(m, n), Cap(B, F) = CapX(m, n).So final electricity of gauze B
Holding result is：Cap(B, A) = Cap1(B, A) + Cap3(B, A), Cap(B, C) = Cap1(B, C) + Cap3
(B, C) + Cap5(B, C), Cap(B, D) = CapX(m, n), Cap(B, E) = CapX(m, n), Cap(B,
F) = CapX(m, n)。
By methods herein, the electric capacity of gauze B in full panel domain is extracted and is converted into the electric capacity in non-array region by we
Value and be converted into by the capacitance of the inside gauze of array element X corresponding outside gauze capacitance simple combination.Pass through
Non-array region division, reduces the calculating of inactive area, accelerates extraction rate；Calculated by a small number of array elements and simple
Capacitance corresponding conversion, reduce and the time loss that numerical method is extracted be used repeatedly, so as to greatly accelerate
The extraction of full panel domain electric capacity.
Brief description of the drawings：
Fig. 1 array areas and non-array area
Fig. 2 non-array Divisions
The inside gauze of Fig. 3 array elements X
The corresponding three different outside gauzes of Fig. 4 array elements X inside gauze
