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

A kind of resistance that waits in flat faced display design connects up implementation method-serpentine wire

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.

Specific implementation step：

Serpentine wire is by connecting up parameter setting and calling serpentine wire application program to complete the method for waiting resistance wiring. Its operating process step is as follows：

1）Select tooth：Select two groups of teeth for waiting resistance distribution to be supported.So-called tooth, that is, treat that wiring graph needs to connect with cabling The one end gone out or a part.

2）Parameter setting：The each parameter value needed for serpentine wire is set, major parameter item and implication are as described above.

3）Preview-modification parameter-preview, so repeatedly until determining final distribution effect：Call self routing application journey Sequence preview distribution effect, if not good, return previous step and remodifies distribution parameter value, preview again, until final satisfied.

4）Generate distribution：Self routing application program is called, what key intelligence generation was final waits resistance wiring scheme.
