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
Snakelike wiring (Snake wiring) is the automatic wiring method of realizing constant resistance requirement in FPD (flat-panel monitor design) field.The invention belongs to self routing design field in FPD instrument.
Background technology
Self routing is the important component part of FPD design field.According to different demands, need different cabling scenarios to support, such as fixed value resistance wiring, side coiling and constant resistance wiring etc. on pel array.Its medium resistance wiring is modal a kind of distribution demand.Resistance (Resistance represents with " R " conventionally) is to use one of maximum element in all circuit.In physics, represent the size of conductor to electric current inhibition with resistance.The resistance of conductor is larger, represents that conductor is larger to the inhibition of electric current.Different conductors, resistance is generally different, and resistance is a specific character of conductor itself.At FPD design field, constant resistance, resistance difference remains in a tolerable limit in other words, can make flat circuits show good performance.
At FPD routing field, a wide cabling (Path), its resistance value is directly proportional to the length of Path, be inversely proportional to width, scale-up factor is determined by physical attributes such as square resistance rates, slightly be subject in addition the impact that resistance reduces slightly that causes that cabling turns round, quantize by turning resistivity.So under the constant prerequisite of trace width, by the different cablings less to original resistance, increasing in varying degrees its track lengths, to increase its resistance value, thereby reaching many cabling constant resistances.
Summary of the invention
The present invention discloses the wiring method-snakelike wiring that automatically realizes constant resistance wiring in a kind of panel designs.According to the difference of the shape of the basic unit body of cabling, the present invention proposes three kinds of distribution shape schemes: the snakelike wiring of rectangle, trapezoidal snakelike wiring and the snakelike wiring of triangle, its cell cube shape is respectively rectangle, trapezoidal and triangle, sees accompanying drawing 1, Fig. 2, Fig. 3.Snakelike wiring with distribution shape like snakelike and name.The present invention further supports the shape with the snakelike cabling of multiple variable parameter control, they are: maximum resistance poor (Max Inter-deviation), maximum/minimum resistance ratio (Res. Max/Min) between serpentine pattern (Pattern), groove size (Notch), amplitude pattern (Equal Amplitude), adjacent traces, these parameters have been determined shape and the effect of snakelike wiring, are important component parts of the present invention.
basic thought: resistance R is the important property of physical device, at FPD routing field, the resistance value of a wide cabling (Path) is directly proportional to the length of cabling, is inversely proportional to its width.Scale-up factor determines by physical attributes such as square resistance rates, is slightly subject in addition the impact that resistance reduces slightly that causes that cabling turns round, and this impact quantizes by turning resistivity.In most of FPD wires design, guarantee that distribution constant resistance can be that flat circuits shows better performance in batches.Even if non-snakelike wiring can not guarantee that under the wide prerequisite of each cabling track lengths equates, thereby causes resistance unequal.The ultimate principle of snakelike wiring is exactly in the situation that guaranteeing that trace width is consistent, by adding the element of the bending snakelike cell cube being wound around to increase the length of small resistor value cabling in cabling, thereby increase its resistance value, finally reach the object of each cabling constant resistance.Snakelike cell cube is divided into 3 kinds, rectangle, trapezoidal, triangle with its shape difference, refers to accompanying drawing 1, Fig. 2, Fig. 3.
In addition, can by the setting of parameter value reach regulate snakelike walk nemaline effect, its major parameter and implication are as follows:
1. serpentine pattern (Pattern): according to the difference of elementary cell shape, serpentine pattern is divided into 3 kinds, rectangle, trapezoidal, triangle, refers to accompanying drawing 1, Fig. 2, Fig. 3.
2. groove size (Notch): represent the size of basic unit body groove in short transverse.
3. amplitude pattern (Equal Amplitude): be divided into one end (Single) and two ends (Dual) two kinds of patterns, refer to respectively insert basic unit body with structure serpentine pattern at one end or the two ends of cabling.
4. maximum resistance poor (Max Inter-deviation), maximum/minimum resistance ratio (Res. Max/Min) between adjacent traces: these two Parametric Representations the degrees of tolerance to resistance difference.So-called constant resistance is not that absolute resistance equates, as long as can accomplish to allow resistance difference in certain tolerance.
