Abstract

The invention further discloses other outline shape features of wing wiring based on an already submitted application 'narrow-bezel wiring achieving method in design of flat-panel display-wing wiring', and particularly discloses a method for achieving wing wiring of narrow-bezel wiring outlines through repeated feature shapes in the design of a flat-panel display. The outline shape features can be an arbitrary triangle (see the graph 1) or an arbitrary trapezoid (see the graph 2) or an arc (see the graph 3) or combination shapes of the triangle, the trapezoid and the arc (see the graph 4), all the corresponding and repeated wing-shaped or wing-similar unit bodies on adjacent connecting line outlines are utilized to form an exposure clearance in a surrounding mode, and then all the feature shapes of the narrow-bezel wiring are achieved based on the principle that the smooth and separated wiring outlines are produced after light penetrates through the clearance and is radiated.

Description

Realized the wing wiring method of narrow frame wiring profile by the character shape repeated in a kind of flat-panel monitor design

Technical field

Wing wiring (Wing wiring) is the wiring implementation method realizing narrow frame demand in FPD (flat-panel monitor design) field.The invention belongs to self routing design field in FPD instrument.

Background technology

The main flow that flat pannel display (FPD) has become future television is trend of the times, but still there is no strict definition in the world at present, general this thickness of displays is thinner, look just as a flat board, the kind of flat pannel display is a lot, divide by display medium and principle of work, have liquid crystal display (LCD), plasma display (PDP), electroluminance display (ELD), ORGANIC ELECTROLUMINESCENCE DISPLAYS (OLED), Field Emission Display (FED), Projection Display etc.

Self routing occupies very large workload in slab design, and demand that should be different, have again the wiring method that many kinds are different in reality, such as wait resistance wiring, fixed value resistance connects up, based on the side wiring on pel array, etc.A kind of important demand is wherein had to be exactly wiring for narrow frame.Narrow frame is frame by reducing screen thus makes screen reach maximization, and the volume of whole panel is also controlled simultaneously, allows you can experience larger screen at the panel of same area.The growing of narrow frame mobile phone is exactly an example.

According to the design requirement of narrow frame, make that wiring is compacter becomes natural wiring criterion.For this reason, the method for minimum space routing strategy, the width reducing cabling etc. can be adopted.For reducing the method for trace width, width is too little can cause open circuit in exposure is produced, and spacing is too narrow can cause short circuit in exposure is produced.So, the width of cabling infinitely can not be reduced in order to narrow frame.That is, we wish to reach the effect that reduces trace width and trace width can not be allowed infinitely to reduce to cause the danger of short circuit.

On the other hand, diffraction (Diffraction) is also called diffraction, is continued the phenomenon propagated after ripple runs into barrier or aperture by scattering.Diffraction phenomena is the endemism of ripple, and all ripples all diffraction phenomena can occur.If allow dull and stereotyped cabling have the wing shape profile of sawtooth like shape, by the effect of photoetching diffraction, the trace width of equal value that one is equivalent to position between zigzag fashion crest and the lowest point will be produced, thus both reached the demand of narrow frame, not be short-circuited again.Wing wiring method is exactly based on this principle.So wing wiring is arisen at the historic moment.

The cabling scenario adopted for adapting to narrow frame demand in general FPD design process draws the cabling with narrow frame profile by mode manually.Inefficiency, process is loaded down with trivial details.In process worse for the transition of cabling turning, the mode of hand drawn is not almost gone down, and except cannot accomplishing the seamlessly transitting of turning, the shape of turning transition also cannot adapt to the diffraction exposure-processed of follow-up link.

Applied for the patent of one section of autograph for " the narrow frame wiring implementation method-wing wiring in a kind of flat-panel monitor design " before.The present invention continues the wing wiring method being realized narrow frame wiring profile in openly a kind of flat-panel monitor design by the character shape repeated on its basis.

Summary of the invention

The present invention before the autograph of submit applications be on the basis of " the narrow frame wiring implementation method-wing wiring in the design of a kind of flat-panel monitor " patent, the other profile shape characteristic of openly wing wiring further, they are all to utilize on adjacent connection lines profile the corresponding wing that repeats or approximate wing cell cube with around formation arbitrary shape exposing clearance, when on the special process layer on the glass that light therethrough exposing clearance is irradiated to below mask, can produce smooth distribution profile, and the profile of every two adjacent groups line is separated.The wing elementary cell shape repeated by these realizes the narrow frame wiring effect be separated.

Wing wiring profile basic unit body shape facility is disclosed as arbitrary triangle (see Fig. 1), arbitrarily trapezoidal (see Fig. 2), circular arc (see Fig. 3) and their combined shaped (see Fig. 4) and all corresponding wing that repeats or approximate wing cell cubes of utilizing on adjacent connection lines profile with around formation arbitrary shape exposing clearance, and the principle then producing the distribution profile of smooth separation after light therethrough gap is irradiated realizes all character shapes that narrow frame connects up.

Accompanying drawing explanation

Fig. 1 wing wiring profile basic unit body is triangle

Fig. 2 wing wiring profile basic unit body is trapezoidal

Fig. 3 wing wiring profile basic unit body is circular arc

Fig. 4 wing wiring profile basic unit body is trapezoidal and leg-of-mutton combination

Concrete implementation step:

Before the autograph of submit applications be on the basis of the concrete implementation step of " the narrow frame wiring implementation method-wing wiring in the design of a kind of flat-panel monitor " patent, to the profile basic unit body shape facility that wing disclosed by the invention connects up, implementation step changes as follows:

1) the port figure of two groups of cablings is chosen, to carry out wing wiring between two groups of ports.

2) wing wiring profile basic unit body parameters for shape characteristic is set.

3) call wing wiring self routing application program preview distribution effect, if not good, return previous step and remodify distribution parameter value, preview again, until finally satisfaction.

4) distribution is generated: call wing wiring self routing application program, a key intelligence generates final wing wiring scheme.
