Abstract

Pattern arrangement simulation drilling method is flat-panel monitor（FPD）Design the method that figure is punched in the quick generation in eda tool field.This method obtains a series of sides as its sense of current, and the figure is divided into several regions by its sense of current by specifying the starting of former panel figure to terminate side.In each area, two groups of equidistant figures are passed through（Rectangle, trapezoidal or other figures）Being uniformly distributed on former panel figure and square crossing, one group parallel to sense of current side, one group, perpendicular to sense of current side, realizes the equivalent effect of punching.Profile, internal bore profile and the frame glue region contour of former panel figure are by a circle polygon covering with this two groups of equidistant figures of envelope.This solves the spine problem that common polygon with holes is produced when doing reduction operation.

Description

A kind of pattern arrangement simulates drilling method

Technical field

Pattern arrangement simulation drilling method is flat-panel monitor（FPD）Design the quick generation punching figure in eda tool field The method of shape.The invention belongs to flat-panel monitor design and EDA design tools field.

Background technology

FPD industry is the foundation stone of the industries such as tablet personal computer booming now, TV, smart mobile phone, production production Product mainly have liquid crystal panel, plasma panel and oled panel etc..At present, China has become the center of world's FPD industries.It is flat Plate is shown（FPD）In the world still without strict definition, general this thickness of displays is relatively thin, it appears that just as a flat Plate.The species of FPD is a lot, by display medium and operation principle point, have liquid crystal display, FED, Projection Display, Plasma is shown, electroluminance display, ORGANIC ELECTROLUMINESCENCE DISPLAYS etc..Flat-panel monitor and traditional CRT（Cathode-ray tube） Compare, there is thin, light, small power consumption, radiation is low, do not flash, be conducive to health.

Liquid crystal display panel abbreviation LCD, is the critical component of LCDs.Its general principle is in two pieces of conductions Filling liquid crystal material between glass substrate, liquid crystal material therein can stop or change light when being changed using external electrical field The characteristic of line realizes display.Electric field is formed when conducting glass substrate is powered up and down, when voltage changes, internal liquid crystal molecule Arrangement situation changes therewith, and liquid crystal molecule shows different shading-transmittings under different angles；In two electro-conductive glass Colored filter on substrate plus three-primary colours can show coloured image.

During the wires design of liquid crystal panel, some polygonal shapes are often created.If polygon is located at frame glue In region, then need to punch on these polygons, to ensure the dutycycle in frame glue region, it is ensured that frame glue is dried solidification.

General punching order is after generation punching figure, and air exercise hole pattern does reduction operation and problem occurs, it can change Become the profile of original figure, as shown in figure 1, the left side is original punching figure, the right is that air exercise hole pattern is done after reduction operation As a result.This paper presents a kind of method of pattern arrangement simulation punching, diminution punching figure produced problem is solved, effect is such as Shown in Fig. 2.

The content of the invention

The present invention proposes a kind of figure distribution simulation drilling method, and English is Seal Slot, and this method is defeated according to user The parameter in the hole entered automatically generates punching figure.

The present invention obtains a series of sides as its sense of current, and press by specifying the starting of former panel figure to terminate side The figure is divided into several regions by its sense of current.In each area, two groups of equidistant figures are passed through（Rectangle, ladder Shape or other figures）Being uniformly distributed on former panel figure and square crossing, one group parallel to sense of current side, one group hangs down Directly in sense of current side, the equivalent effect of punching is realized.The profile of former panel figure, internal bore profile and frame glue region contour are equal By a circle polygon covering with this two groups of equidistant figures of envelope.Reduced this solves common polygon with holes The spine problem produced during operation.

The figure distribution simulation drilling method of the present invention provides the parameter setting interface in hole.As shown in Figure 3.

After parameter setting is finished, that specifies the figure that is perforated plays initial line and termination side, Apply buttons is clicked on, in domain Punching figure will be automatically created.

The present invention proposes the parameter of the shape in a set of description hole.Make introductions all round below：

1）Path Width, represent path width；

2）Slot Max Width, represent the width in hole；

3）Slot Max Length, represent the length in hole；

4）Result Layer, represent the process layer of generation punching figure；

5）Seal Layer, represent the region punching only covered in this process layer；

6）Reference Edge（left）, represent that the sense of current is playing the left side of initial line；

7）Reference Edge（right）, represent that the sense of current is playing the right of initial line；

8）Reference Edge（up）, represent that the sense of current is playing the top of initial line；

9）Reference Edge（down）, represent that the sense of current is playing the following of initial line；

10）Current Edge Length >, represent that length will be ignored less than the electric current side of this value；

11）Start, an initial line for selection object；

12）End, selects the termination side of object；

13）Start/End/Match Count, represent to have selected the quantity of initial line respectively, terminate the quantity on side and pass through Play initial line, terminate the quantity that side determines punching object.

Specific implementation step：

Illustrate Seal Slot automatic generation methods with reference to a specific example, operating process step is as follows：

1）Start Seal Slot orders in AetherFPD instruments, as shown in figure 4, inputting following join in dialog box Number：

Path Width are set to 40；

Slot Max Width are set to 40；

Slot Max Length are set to 80；

Result Layer are set to GATE；

Reference Edge are set to left and up；

Seal Layer and Current Edge Length choice boxs are not chosen；

2）Start buttons are clicked on, as shown in figure 5, mouse frame selects an initial line for object；

3）End buttons are clicked on, as shown in fig. 6, mouse frame selects an initial line for object；

4）Apply buttons are clicked on, figure is punched in generation, as shown in Figure 7.
