Abstract

Flat-panel displayers, especially liquid crystal displayers, are the first choice of modern electronic product displayers, and occupy larger and larger market. In the field of layout design of flat-panel displayers, when panel peripheral IC circuits and control circuits are drawn, due to the fact that the number of chip pins is large, a panel design engineer needs to draw coordinates of the pins by hand according to requirements, accuracy is poor, and efficiency is low. By means of a method for generating Teeth in a batch mode, pin Teeth in the layouts can be automatically generated according to text files, containing information like coordinates of the Teeth with the pins and others, provided by panel manufacturers, the generated Teeth also can automatically carry label information of each pin, in addition, according to the requirement of actual layout drawing, and the method further provides the option that whether the Teeth generated in the batch mode are directly connected with fake teeth composed of teeth with the same label or not and the option whether a wiring command is directly started for wiring or not.

Description

The method of Mass production Teeth a kind of

Technical field

This Mass production Teeth method is applied in EDA flat pannel display (FPD) device layout design.The invention belongs to flat-panel monitor design and eda tool layout design field.

Background technology

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

Since the nineties, along with the breakthrough of technology and the sharp increase of the market demand, flat pannel display (FPD) technology take liquid crystal display (LCD) as representative is emerged rapidly.Through research, competition, the development of two more than ten years, flat-panel monitor is got inside the character that one is playing, become the main product of new century display, most hotly competitive flat-panel monitor has 2. 3. 4. tft liquid crystal flat-panel monitor (TFT-LCD) of organic thin film electroluminescent device (OLED) of plasma panel display (PDP) of four strains 1. field-emission plane displays (FED) at present.

Liquid crystal display, or claim LCD(Liquid Crystal Display), be the display device of planar ultra-thin, it is made up of colour or the monochrome pixels of some, is positioned over light source or reflecting surface front.Liquid crystal display power consumption is very low, and therefore extremely slip-stick artist favors, and is applicable to use the electronic equipment of battery.Its cardinal principle is to produce point, line, surface with galvanism liquid crystal molecule to coordinate back fluorescent tube to form picture.

Liquid crystal flat panel display domain is mainly divided into liquid crystal pixel array (Array) and driving circuit (Driver) part, and driving circuit section comprises again IC and FPC chip drive circuit.In the time drawing the domain of this part, often there is no ready-made a large amount of chip pin (Pin is called Teeth herein) data, need manual drawing.Dull and stereotyped manufacturer can provide a received text file with IC Teeth and FPC Teeth information, and domain slip-stick artist needs manually information extraction from this file, and in layout editing instrument, draw manual location.

Summary of the invention

The present invention proposes the method for IC Teeth and FPC Teeth in a kind of Mass production liquid crystal flat panel display (FPD) design.This method by read the mode of text disposable, automatically in layout editing instrument, generate Teeth in large quantity.

Basic thought: the IC circuit and the FPC circuit that need to design control signal in flat-panel monitor design around liquid crystal pixel array.Port Teeth, represents the chip pin (Pin) in IC circuit or FPC circuit.Each Pin has the title (label) of a Pin according to electrical specification, be recorded in the text of IC and FPC in the mode of character string.This text can also record the coordinate of each Teeth in layout editing instrument.Layout editing instrument provides to browse and selects the interface of single IC tooth and FPC dental cast example (instance) and read this IC and the interface of FPC text.First user selects the instance of these two kinds of Teeth, then arranges according to the information in file and other some parameters, and automatic batch generates two kinds of Teeth.

In these two kinds of Teeth, the pin with identical Label has identical electrical specification, consider the needs of follow-up distribution between IC Teeth and FPC Teeth, the method for this Mass production tooth can also couple together adjacent pseudo-tooth for the tooth with identical Label (FakeTeeth) mode automatically.And a kind of option setting is provided, after the qualified Teeth of Mass production, automatically opens the follow-up distribution order of layout editing software.

Concrete implementation step:

The generation method that this batch tooth is described in conjunction with a concrete example, operating process step is as follows:

1) open EDA edit tool, IC tooth that cloth need to generate and the parameter of FPC tooth are set, as shown in Figure 1;

2) import the text with IC tooth information, file layout as shown in Figure 2;

3) import the text with FPC tooth information, file layout as shown in Figure 3;

4) browse and select as the instance of IC tooth as shown in Figure 4;

5) browse and select as the instance of FPC tooth as shown in Figure 5;

6) click and generate tooth button, Mass production IC and FPC tooth, and on the corresponding tooth generating automatically with label information, effect is as shown in Figure 6;

7) if need to generate pseudo-tooth, can arrange on interface and choose and generate pseudo-tooth at edit tool, to click and generate tooth button, Mass production is with IC and the FPC tooth of pseudo-tooth, and as shown in Figure 7, the single Teeth effect with Label of generation is as shown in Figure 8 for effect;

8) if need to directly carry out distribution operation after Mass production Teeth, can arrange on interface and choose and start distribution order at edit tool, click can start the distribution order in edit tool after generating tooth button automatically, can proceed distribution and operate

Claims

1. a method of Mass production Teeth, the principal character that relates to EDA layout tool is:
