Abstract
The invention discloses a method for achieving equal-resistance snakelike wiring in flat-panel display design. According to the method, three wiring shape schemes, namely, rectangular snakelike wiring, trapezoidal snakelike wiring and triangular snakelike wiring, are provided according to different shapes of basic units for wiring; the basic units are rectangular, trapezoidal and triangular respectively, please see the Figure 1, the Figure 2 and the Figure 3. The wiring method is named as 'snakelike wiring' based on the fact that the wiring shape seems like a snake. By means of the method, the snakelike wiring shape can be controlled through various variable parameters, including the snakelike pattern (Pattern), the notch size (Notch), the amplitude mode (Equal Amplitude), the maximum resistance deviation between adjacent wires (Max Inter-deviation) and the maximum/minimum resistance ratio (Res. Max/Min), and the parameters guarantee the snakelike wiring shape and the snakelike wiring effect and play an important role in the method.
Description
Technical field
Serpentine wire (Snake wirings) is the automatic cloth for the resistance requirement such as realizing in FPD (flat faced display design) field
Line method.The invention belongs to self routing design field in FPD instruments.
Background technology
Self routing is the important component part of FPD design fields.According to different demands, different cabling scenarios are needed
To support, such as fixed value resistance wiring, the side coiling on pel array and wait resistance wiring etc..Its medium resistance is connected up
A kind of modal wiring needs.Resistance(Resistance, is generally represented with " R ")It is elements most used in all circuits
One of.In physicss, size of the conductor to electric current inhibition is represented with resistance.The resistance of conductor is bigger, represents conductor
It is bigger to the inhibition of electric current.Different conductors, resistance are typically different, and resistance is a kind of characteristic of conductor itself.Set in FPD
Meter field, waits resistance, and resistance difference is maintained in a tolerable limit in other words, shows can flat circuits excellent
Performance.
In FPD routing fields, a wide cabling (Path), its resistance value is directly proportional to the length of Path, with width
It is inversely proportional to, proportionality coefficient is determined by physical attributes such as square resistance rates, is additionally slightly caused resistance slight by what cabling turned round
The impact of reduction, is quantified with turning resistivity.Then on the premise of trace width is constant, by it is less to original resistance not
Same cabling, increases its track lengths to varying degrees, to increase its resistance value, so as to reach the resistance such as a plurality of cabling.
The content of the invention
The present invention such as is automatically obtained at the wiring method-serpentine wire that resistance is connected up in disclose a kind of design of panel.According to walking
The difference of the shape of the basic unit body of line, the present invention propose that three kinds are matched somebody with somebody wire shaped scheme:Rectangle serpentine wire, trapezoidal snakelike cloth
Line and triangle type serpentine wiring, its unit shape is rectangle, trapezoidal and triangle respectively, sees accompanying drawing 1, Fig. 2, Fig. 3.Snakelike cloth
Line with wire shaped like snakelike and name.The present invention further supports the shape that snakelike cabling is controlled with various variable parameters, it
Be:Between serpentine pattern (Pattern), groove size (Notch), amplitude modes (Equal Amplitude), adjacent traces most
Big resistance difference (Max Inter-deviation), maximum/minimum resistance ratio (Res. Max/Min), these parameter determinations
The shape and effect of serpentine wire, is the important component part of the present invention.
Basic thought:Resistance R is the important attribute of physical device, in FPD routing fields, a wide cabling
(Path) resistance value is directly proportional to the length of cabling, is inversely proportional to its width.Proportionality coefficient is belonged to by physics such as square resistance rates
Property determine, additionally slightly caused resistance slightly to reduce to be affected by what cabling turned round, this is affected with the quantization of turning resistivity.
In most of FPD wires designs, it is ensured that the resistance such as batch distribution can be that flat circuits show more excellent performance.Non-serpentine cloth
Even if line on the premise of each cabling is wide it cannot be guaranteed that track lengths are equal, so as to cause resistance unequal.Serpentine wire
Ultimate principle is exactly in the case where ensureing that trace width is consistent, by the serpentine sector body for adding bending winding in cabling
Element to increase the length of small resistance value cabling, so as to increase its resistance value, be finally reached the purpose of the resistance such as each cabling.Serpentiss
Shape cell cube is divided into rectangle, trapezoidal, 3 kinds of triangle with its shape difference, refers to accompanying drawing 1, Fig. 2, Fig. 3.
Furthermore, it is possible to the setting for passing through parameter value reach regulation it is snakelike walk nemaline effect, its major parameter and implication
It is as follows:
1. serpentine pattern (Pattern):According to the difference of elementary cell shape, serpentine pattern be divided into rectangle, it is trapezoidal, three
Angular 3 kinds, refer to accompanying drawing 1, Fig. 2, Fig. 3.
2. groove size (Notch):Represent size of the basic unit body groove in short transverse.
3. amplitude modes (Equal Amplitude):It is divided into one end (Single) and two ends (Dual) both of which, respectively
Refer in one end of cabling or two ends insertion basic unit body to construct serpentine pattern.
4. maximum resistance poor (Max Inter-deviation), maximum/minimum resistance ratio (Res. between adjacent traces
Max/Min):The two parameters illustrate the degrees of tolerance to resistance difference.It is so-called to wait resistance, it is not that absolute resistance is equal, only
Can accomplish to allow resistance difference in certain tolerance.
